This application is based on, and claims the benefit of priority to, Applicant's co-pending U.S. Provisional Patent Application Ser. No. 60/163,996 (filed on Oct. 27, 1999), Ser. No. 60/164,656 (filed on Nov. 4, 1999), Ser. No. 60/164,597 (filed on Nov. 10, 1999), Ser. No. 60/169,149 (filed on Dec. 6, 1999), Ser. No. 60/194,767 (filed on Apr. 3, 2000), Ser. No. 60/208,619 (filed on Jun. 1, 2000), Ser. No. 60/220,578 (filed on Jul. 25, 2000). The entire disclosure of all of the above-mentioned applications are hereby incorporated by reference herein as fully as if set forth in their entirety.
This invention relates to keypad, finger, hand, speech, lips, face and other detection systems, and more specifically to a keypad (e.g. standard telephone keypad), having a finger pad recognition device which may be used in combination with the above-mentioned recognition systems, in order that full text and functions input can be provided in a natural, easy and quick manner.
Miniaturization has been a key component to recent technological advancement, enabling production of many devices that would otherwise be impracticable for reasons of size alone. Thus, we now have desktop computers that are more powerful and much smaller than their ancestor mainframes. Also, digital clocks, video games and common appliances farther illustrate the profit of miniaturization. In fact, the very essence of, for example, portable computers and cellular phones is their size as a primary feature.
Yet, primarily because of human constraints, there are many obstacles to the growth of miniaturization in several areas. For example, it may be desirable to have a portable computer that fits in one's wallet, but such a computer would not be useable without a large input device that enables human interaction with the computer. In other words, complex miniature computers and devices, such as cellular phones (now, also used for the Internet, email, m-commerce, SMS (Short Massage Services), etc.), notebooks and PDAs, require keyboards, numeric pads or other input devices to allow the user to enter a phone number, send e-mail or transcribe a letter, etc. Thus, as advanced as miniaturization technology may get, there are other human factors involved that prevent certain devices from realizing a truly miniature state.
As is well known, the key feature for a successful technological product, is its easily manipulations. For above-mentioned instruments and similar devices, a quickly, easily and most importantly, naturally, full text and function entry system is vital.
The telephone-type keypad, that people are familiar with, is the most common input device for small electronic and telecommunications instruments. It is integrated in many electronic devices such as mobile and wired telephones, PDAs, notebooks, laptops, faxes, remote controllers of TVs or other electronic devices, cameras, etc. This keypad usually has twelve keys, while the number of characters and functions keys used for writing texts or messages may be seven times this number. For example a computer keyboard has more than eighty keys, while some of those keys are used for two characters, symbols, or functions.
Because the telephone keypad has an insufficient number of keys (e.g. mobile phone keypad), each key of a standard telephone keypad contains a group of characters and usually one number. Usage of the Internet or even entering a short message, engages a lot of complexity for the consumer.
Proposals have been put forward to solve this fundamental man-machine-interface problem of how to quickly and easily enter text and functions using small communication devices.
One solution is to provide multiple presses of a single key for selecting a letter or symbol among those represented by a key. This system is currently used in most mobile phone keypads. This is a time consuming method and it frustrates the user.
To improve that system, word disambiguating software products are developed. A dictionary database and language model are used to scan and present possible words according to keys pressed. Later the user selects the desired word among presented possibilities. Such approach engages a lot of problems such as out-of-vocabulary words or obliging the user to concentrate for selecting a desired word. In addition, entering numbers or single characters are again time consuming procedures.
External miniaturized keyboards are also produced to overcome the problem but they oblige the user to carry two different instruments, interfering with the basic idea of small electronic products, which is their easy portability.
One recent technology that has attempted to overcome such limitations is voice/speech-recognition technology. Voice recognition is the process of recognizing one or more voice patterns from an individual's voice as a corresponding computer input command, word, or function. For example, rather than typing a letter on a keyboard a user speaks that letter, wherein the recognition device associates the voice pattern of that letter with the corresponding computer input character of that letter. Thus, individuals may operate devices in this manner without an input device since the user's voice provides all of the input. Unfortunately, considering the many complex aspects of an individual's voice, there is yet a recognition device that can accurately recognize voice patterns at a sufficient level where input devices can be completely replaced.
Additionally, several letters such as "B" and "P", or "D" and "T", can easily be confused by a speech engine. This is not necessarily a shortcoming of the engine as these letters can easily be confused by the humans as well. Hereafter, a list of some of the problems and disadvantages concerning voice/speech recognition systems;
Moreover, notwithstanding the miniaturization issue, portable and other electronic devices have many security and efficiency problems. For example, an individual who misplaces or loses a cellular phone must rush to disconnect his or her communications service before a thief or other person uses the phone to generate unauthorized charges. One known method for preventing such unauthorized use is to lock the cellular phone or other device with a code system. Although, effective in many cases, this system is painstaking and inefficient for the true owner, who must activate the phone via a lengthy process before dialing. Similarly, there is no simple method for preventing unauthorized use of many electronic devices without first locking the device with a code system or other time consuming and inefficient process.
Therefore, what is needed is a technology that resolves the human constraint Dilemma mentioned above, so that miniaturization can continue to realize its true potential. Furthermore, such a technology should also provide means for a more secure and efficient mechanism that can prevent unauthorized use of devices, among other things, as compared with the prior art. In addition, a technology that improves the reliability of voice recognition technology is desirable as well. What is needed, is preferably, a character-by character data entry method, using familiar input devices with limited number of keys (e.g. telephone keypad), wherein each key contains a group of characters, symbols and commands existing on computer keyboards or similar devices, combined with some of other recognition systems such as finger, voice, speech, lip, eye, face, etc., to enable the identification of individual characters from individual key entry actions.
A fingerprint detection device is provided, comprising one or more electronic pads that are configured to recognize pattern differences in each of a user's fingers. Such patterns relate to finger characteristics (such as size, shape, color, etc.), of entire fingers or portions of them. The patterns also relate to other information such as characteristics of the surface of the fingertips (fingerprint, size, shape), nails (shape, size, brilliance), etc. Such pattern differences can in turn be utilized communicatively so that human input can be transmitted to an electronic device via the process of touching one's fingers to the fingerprint detection device. Thus, an individual can use one's fingers in conjunction with a fingerprint detection device in order to input a phone number to a phone device, enter characters to a computer, trigger various macros or functions with a PDA, etc.
Initially, the fingerprint detection device must be programmed or 'taught' so that it maps a particular finger with a corresponding symbol or function, such as a number, letter, macro or other activity. Thus, for example, one can use this method to map a distinct number to each of one's fingers (e.g. the numbers 0 to 9 comprise 10 Arabic digits, which may correspond to each one of a person's ten fingers) and then be able to dial phone numbers solely with one's hands and a fingerpad. This saves space, by requiring only one pad as opposed to many numeric keys.
Notably, more than one symbol or function can be mapped to each finger. For example, the fingerprint detection device is configured, according to one embodiment of the invention, to interpret a double tap with a particular finger to correspond to one number, while at the same time a single tap with the same finger can correspond to another number.
Illustratively, using an index finger with one tap can correspond to the number '2' and the same finger used with two taps can correspond to the number '7.' In turn, all ten Arabic digits can be inputted with one hand and one fingerprint pad. Similarly, one can expand on this method to input letters, symbols or other functions.
In alternative embodiments, each finger is mapped to a different symbol or function based on the location of the finger, such as a different corner of the electronic pad. Thus, a tap in the upper right hand corner of the electronic pad will be interpreted differently than the lower right hand corner, etc. Also, more than one pad can be provided, if desired, to accomplish the same purpose.
One main advantage of this fingerprint detection device is its size. Rather than having a large numeric keypad for a phone, one can use a smaller fingerprint pad, using the methods discussed above. Similarly, computer keyboards can be replaced or modified, as well as PDA input devices, etc.
According to one embodiment, the fingerprint detection device is configured to distinguish between fingers based on their fingerprints. As such, this provides the user with a security advantage since the fingerpad would only operate based on a particular finger and is rendered useless in the hands of an unauthorized user.
According to yet another embodiment, the finger detection device detects biological differences between characteristics of fingers via a method other than fingerprint detection. These biological differences include, size, shape, position, temperature, etc. Thus, for example, the finger detection device can be configured to quickly distinguish one finger from another based on its size and shape. This process avoids the lengthy and complex task of scanning a full or partial fingerprint. It is understood that for finger print or finger biological recognition, different detection systems and devices such as sensitive touchpads of any kind, touch screens, thermal, optical or other recognition means may be used.
According to yet another embodiment of the invention, the detection device is configured to accept multiple forms of input to enhance accuracy and ease of use. For example, the detection device can be configured as both a finger detection and voice-recognition device, wherein the detection device identifies a corresponding character or function based on input from both an individual's finger and voice patterns.
Not only does this method enhance accuracy, but it also enables individuals to more easily and quickly input distinct characters, words, and/or functions. Illustratively, without this method, an individual who wishes to use his or her fingers to input alphanumeric characters must assign three or more letters or symbols to each finger since there are many more letters and numbers than human fingers. It is thereafter not sufficient to merely tap one's finger when entering a character since the input device still needs to distinguish between the several characters assigned to that finger. Thus, providing multiple forms of input resolves this problem. As an individual places one's finger on the detection pad he or she may also speak the desired letter or function. The voice of the individual enables the detection device to distinguish between the many characters assigned to a particular finger. In addition, the limitations of voice recognition are avoided since the finger detection device narrows down the voice-recognition to one of a few letters or symbols rather than a much larger scope. For example, by using this system combined with telephone keypad character arrangement, letters "B" and "P" will not be misrecognized by the voice recognition engine, since they are separately located on two different groups (e.g. keys) 2, and 7. The same is true for the letters "D" and "T", which are located on the keys 3, and 8, respectively.
It is understood that the above-described embodiment can be configured to utilize voice-recognition with any of the finger detection devices described herein. For example, voice 6) recognition can be combined to operate with fingerprint detection. Further, voice recognition can also be combined to operate with finger detection based on biological characteristics other than fingerprints. It can also be configured to operate with the optical scanning devices, described herein, etc.
The above description sets forth rather broadly the more important features of the present invention in order that the detailed description thereof that follows may be understood, and in order that the present contributions to the art may be better appreciated. Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for the purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims.
In the drawings in which like reference characters denote similar elements throughout the several views:
With initial reference to
Fingerprint detection interface 100 further comprises, according to one embodiment of the invention, a display screen 122, an indicator light 124, command buttons 128–136, switches 138, and wireless communications means 126. Briefly, an individual using a plurality of fingers, such as fingers 102–120, touches fingerprint detection pad 126 in order to provide an input signal, whereas fingerprint detection device 100 in turn transmits that signal via communications means 126 to another device, such as a phone or computer. The type of input signal provided is based on a combination of factors, including, which finger or portion of a finger is used and what motion is done with that finger. For example, an individual can double tap his or her right thumb to provide one signal and swipe his or her left index finger to provide another signal. The method and use of such fingerprint detection will be described in more detail below. Thus, the fingerprint detection device can be used in place of a more bulky computer keyboard, phone numeric pad, or any other input device.
With continued reference to
In addition, indicator light 124 can be configured to flash and/or beep to indicate the operation of the fingerprint device. Thus, an individual can use the fingerprint pad without viewing the display screen, and the indicator light will flash or beep as the fingerprint detection mechanism for each finger is completed. This signals the individual user with an indication so that he or she may continue to another finger or signal.
As mentioned above, command buttons 128–136 provide several useful functions. For example, command buttons 128 and 130 can be used to initiate or program the device. Understandably, the fingerprint detection device must be programmed or 'taught' so that it maps a particular fingerprint with a corresponding symbol or function, such as a number, letter, macro or other activity. Thus, command buttons 128 and 130 can function as record and select buttons so that one or more symbols or functions can be selected and mapped with a particular fingerprint. Furthermore, command buttons 132 and 134 can be used to respectively clear and transmit the information in a buffer or on the display screen. Similarly, command button 136 can instruct the fingerprint device to bypass a buffer system and directly transmit all information to the corresponding device, such as a phone. Of course, in one embodiment, there may be no command buttons, wherein the entire functionality of the system is accomplished via the fingerprint pad.
In addition, switches 138 provide additional functions such as a power on/off switch, detection mode switch, individual user switch, etc. For example, the fingerprint device can be designed to map the fingerprints of more than one individual. For efficiency purposes, one of the switches can be configured to indicate which individual is using the finerprint device, reducing the processing time of the device by limiting the number of fingerprints that have to be matched. Moreover, a detection mode switch can be utilized to indicate the primary use, such as whether the fingerprints should be interpreted as numbers, letters, functions, etc. Thus, when typing a letter, the switch can instruct the device to map single finger taps to commons letters, whereas when dialing a phone number, the switch can instruct the device to map single finger taps to numbers, etc.
It is understood that the fingerprint device as shown is but one embodiment of the invention and is not limited as such. In an alternative embodiment, the fingerprint device can be incorporated as part of a computer or telephone, rather than a separate external device. In addition, any technology aside for wireless communication can be used.
With reference to
Illustratively, tapping once with a finger corresponding to identification number 212 may produce the number '0,' whereas the same finger with a double tap may produce the number '6.' In turn, all ten Arabic digits can be inputted with one hand and one fingerprint pad, by only using single and double taps. Similarly, one can expand on this method to input letters, symbols or other functions, such as by using glide motion 210, etc.
Of course, the mapping table can be instructed to only map one of several fingers, entirely or partially, as needed. Similarly, the mapping table can assign the same function or symbol to multiple fingers or the same finger on corresponding hands, etc.
Notably, the mapping table of

Similarly, with reference to
It is understood that the fingerprint detection device described above and herein can be configured to operate in one of many environments. For example, individual fingers can be mapped to musical notes, wherein an individual can play music by tapping his or her fingers on a fingerprint pad. According to this embodiment, seven fingers can be assigned to seven different notes or more, and different pads or different portions of one finger or one pad can be assigned to a higher or lower tone, etc.
In yet another embodiment the fingerprint device can be configured to scan only a minimal portion of one's finger, rather than the entire finger. In this embodiment, the device is not necessarily concerned with security measures, but with distinguishing one finger from the other finger or one portion of a finger from another portion of same finger or another finger. Therefore, only the minimum amount of scanning is needed, just enough to know which finger or portion of it is being used. Of course, the device can be configured to scan more or less depending on the priorities of security vs. speed.
In yet another embodiment of the invention, a device can be configured to scan for biological differences among an individual's fingers, other than fingerprints. These biological differences include, size, shape, position, temperature, etc. Thus, for example, the fingerprint detection device can be configured to quickly distinguish one finger from another based on its size and shape, etc. This process avoids the lengthy and complex task of scanning a full or partial fingerprint.
According to one embodiment, this process of scanning for biological differences is only concerned with distinguishing between fingers of one person. Thus, the fingerprint detection device only needs to decipher the shape and/or size of a finger to distinguish a thumb or a portion of a thumb from an index finger or a portion of an index finger, for example, from among five fingers of a hand or the ten fingers of two hands. This is a simpler and quicker task than having to distinguish the thumb of one person from the thumb of another. This process may be accomplished via a database of multiple thumbs, index fingers, etc. As a person touches the fingerprint pad, the detection device matches that finger with the many 'template' fingers in the database. A finger that matches most nearly to a thumb, for example, would be categorized as a thumb, etc. Of course, individuals may program or "teach" the system to recognize their individual fingers more efficiently.
With reference to
Thus, individuals can dial phone numbers or enter characters via the scanning device without touching a pad. In fact, an individual's fingers can be configured to operate as a remote control, wherein the scanning device would be connected to a device, such as a television. For example, an individual can signal with finger 704 to indicate that the volume of a television should be increased. Similarly, another finger can manipulate the channel control of a television. Indeed, the remote scanning device can be situated within any one or more of electronic appliances, light switches, water and bathroom fixtures, etc. In order to avoid unwanted activation of the detection device, an individual can point or signal with the desired finger so that the detection device knows that is should commence scanning.
With continued reference to
It is understood that the above-mentioned embodiments are only examples of many methods that can be used to detect and identify a finger, or different portions of a finger, via the system of this invention. For example, nail detection can be used according to one embodiment of this invention, wherein different fingers are identified based on differing nail structure, size or appearance.
It is understood that in order to enhance the security of the device, the scanning device, according to one embodiment of the invention, can be programmed or taught to better recognize the image of an individual's finger. One such programming method involves the scanning of each of an individual's fingers from several angles so as to generate a 3-dimensional computer image of the scanned fingers. This process enables the fingerprint detection device to better detect a finger or portions of it, regardless of whether it is positioned straight or sideways, etc., since it is a complete image of all angles of the finger. In addition, according to one embodiment, each finger can be assigned to a
Another method of indication the direction of a finger, according to one embodiment, is to first position the finger normally, for regular scanning and/or detection. Then, the finger can betwitched to the side or upwards, to indicate a different input command, etc.
Furthermore, according to another embodiment, multiple fingers can be used together in addition to them being used separately. For example, an index finger can correspond to one letter or number, a thumb can correspond to another, and both a thumb an index finger used together can correspond to yet another character, number, etc.
According to another embodiment, the scanning device can be used in conjunction with a pad. Thus, the scanning of an individual's fingers begin before the pad is touched, but the complete scan is not executed until the finger touches the pad. This feature may be desirable for those who want the assurance that accidental finger motions will not activate the detection device. Furthermore, it is more comfortable to some, when there is a pad or other platform to rest one's fingers as he or she is dialing a phone number, for example. It is understood that the scanning could be made by the pad (e.g. sensitive pad of all kind) itself, creating two or three dimensional images. The images may be assigned to different symbols or functions. For example, touching the pad with a finger in upward position (e.g. tip) can correspond to a function or character and touching the pad with the same finger or another finger in regular position (e.g. flat) may correspond to another function or number.
According to yet another embodiment of the invention, the detection device is configured to accept multiple forms of input to enhance accuracy and ease of use. For example, the detection device can be configured as both a finger detection and voice-recognition device, wherein the detection device identifies a corresponding character or function based on input from both, an individual's finger and voice patterns.
Not only does this method enhance accuracy, but it also enables individuals to more easily and quickly input distinct characters, and/or functions. Illustratively, without this method, an individual who wishes to use his or her fingers to input alphanumeric characters must assign three or more letters or symbols to each finger since there are many more letters and numbers than human fingers. It is thereafter not sufficient to merely tap one's finger when entering a character since the input device still needs to distinguish between the several characters assigned to that finger. Thus, providing multiple forms of input resolves this problem.
As an individual places one's finger on the detection pad, he or she may also speak the desired letter or function. The voice of the individual enables the detection device to distinguish between the many characters assigned to a particular finger. In addition, the limitations of voice recognition are avoided since the finger detection device narrows down the voice-recognition to one of a few letters or symbols rather than a much larger scope.
Furthermore, using multiple forms of input is beneficial from a processing perspective as well. Even if only one function or character is assigned to each finger, using voice recognition, for example, eases the burden of the finger detection device by providing direction as to how to process the finger. Thus, a detection device can utilize information from both the voice and finger recognition devices to converge on an accurate detection result more quickly and with more accuracy.
With reference to
Illustratively, one method of providing input via detection device 800 is to first have a finger, such as finger 808, scanned by optical device 802. It is understood that in an alternative embodiment voice recognition or another form of scanning can be conducted first. Thereafter, in response to the recognition device, display screen 806 displays the one or more letters, symbols or functions associated with that finger. For example, finger 808 may be associated with the number 2, the letters A, B and C, and the symbol @. It is understood that the method of this embodiment can be configured to operate without display 806. Now, the individual, such as individual 810, has several options. One option is to tap finger 808 one or more times to indicate which of the four characters or symbols to select. Another option may be to hold finger 808 in place until the desired character or symbol flashes or provides another indication. Another option may be to use voice-recognition, as described above. According to this option, individual 810 provides a voice sample, corresponding to the desired character or symbol, and detection device 800 selects that symbol via voice recognition device 804.
This process overcomes many of the limitations of finger and voice detection technologies. By having two forms of input, such as both voice and finger patterns, the device is better able to isolate and identify the corresponding character or function, etc. For example, since the voice recognition device is only required to select from a small list of characters and/or symbols the limitations of inaccurate voice recognition is mostly avoided.
In fact, according to one embodiment of the invention, one of the forms of input can be via a numeric keypad or other standard input device, such as a telephone keypad. With reference to
It is understood that the above-described embodiment can further be configured to utilize voice-recognition with any of the finger detection devices described herein. For example, voice recognition can be combined to operate with fingerprint detection. Further, voice recognition can also be combined to operate with finger detection based on biological characteristics other than fingerprints. Voice recognition can also be configured to operate with any other device, such as eye direction recognition system, in addition to the optical scanning device described in
Notably, according to one embodiment of the invention, a finger detection device can be configured to assign all commonly used symbols and characters among the ten fingers of an individual's hand. Illustratively,
According to yet another embodiment, the finger pad detection device of this invention can be configured to operate as a keyboard. Illustratively, with reference to
With reference to
Indeed, with reference to center finger pad section 1104 there are no keys, but rather a flat pad. When a typist initially places his or her fingers on the center pad the detection device calibrates the location of the keys based on the location of the person's corresponding fingers. Thus, a typist can have the letters 'Q,' 'A,' and 'Z' assigned to his or her left pinky. Upon calibration, the location of the typist's pinky will correspond to the letter 'A' and the location below or above the letter 'A' will correspond respectively to the letters 'Z' and 'Q' when that area is touched by the left pinky. Similarly, the left pointer finger can be assigned to multiple letters, such as 'F,' 'G,' "T,' 'V' and so forth. The center finger pad uses finger detection and calibration location to determine dynamically which key is being pressed. According to one embodiment, the finger pad keyboard re-calibrates the position of the keys each time an individual removes his or her hand from the keyboard.
According to one embodiment of the invention, perimeter finger pad sections 1106–1114 correspond to various functions. For example, touching pad section 1108 with one's right pinky can correspond to the 'shift' key on a traditional keyboard. Similarly finger pad section 1110 can correspond to the space bar key of a traditional keyboard when touched with one's thumb. Alternatively, according to one embodiment, touching any of the finger pad sections with one's thumb can correspond to the space bar key.
According to yet another embodiment of the invention, center finger pad section 1104 can be configured to operate simultaneously as a display screen or video output device. Thus, both the monitor and keyboard of a computer, for example, can be integrated as one device. This is possible because the keys are replaced with finger detection pads, providing a flat or nearly flat surface for a display image.
In an alternative embodiment, the above mentioned integrated display screen can be configured to provide one or more displays corresponding to the use of the finger pad keyboard. For example, each time the keyboard calibrates itself based on the position of the typist's fingers the integrated display screen can display images of the corresponding keys in their calibrated location. In addition, the displayed images can highlight when pressed to indicate to the typist that a particular letter or command was detected. In addition, the integrated display can be configured to change its appearance based on different languages or arrangements of letters etc.
According to yet another embodiment of the invention, the finger pad detection device of this invention can be configured to operate as an enhanced keypad. Illustratively, with reference to
According to one embodiment of this invention, a finger detection keypad is provided (
According to one embodiment, the above mentioned finger detection keypad can be configured such that when a key is pressed the corresponding number is output by default. In order to output one of the corresponding letters one may use a particular assigned finger. Thus, a particular middle finger can be assigned to the middle letter of a keypad key, such as 'B' or 'E,' etc. Similarly a right finger to a right key letter and so on. All other fingers or a non-detected or assigned finger can correspond to the default number.
With reference to
Keypad 1300 comprises a plurality of keys, such as key 1320, and a plurality of command buttons, including Alpha button 1308, PC command button 1310, Power button 1312, Send/End button 1314, Menu button 1316, and Execute button 1318. Briefly, these command buttons are configured to perform tasks such as switching the display mode, operating a menu structure, turning on or off the power, etc.
Command buttons 1308 and 1310, when employed, select one of several different configurations. For example, with continued reference to
Thus, many characters, numbers and symbols can be selected via the enhanced keypad 1300 without having to add any extra keys. As a further illustration, if a user wishes to select the letter '0,' for example, he or she first selects the Alpha 2 configuration 1304 via command button 1308. Thereafter, the user selects key 1320, which corresponds to the key with the desired symbol. Since this selection is still ambiguous, the user then provides another form of input. This other form of input can be voice recognition, lip recognition, or finger detection etc. For example, the user may pronounce or speak the letter '0' as he or she presses key 1320 to make that selection. If the user did not provide one of the above-mentioned inputs then the key would default to a particular symbol or function, such as the upward facing arrow function.
It is noted that, according to one embodiment, not every character, function, or symbol is available at the press of one key. For example, rarely used symbols or functions can be assigned to multiple buttons. Illustratively, if the symbol '>' was rarely used, for example, it could be assigned to two keys rather than one. Thus, in order to select the '>' symbol, the user must then simultaneously press the two assigned keys. This is advantageous for those desiring a less cluttered keypad, etc. In addition, using such a technique enables the configuration of an even smaller enhanced keypad.
Notably, enhanced keypad 1300 can be configured according to one of several embodiments. According to one embodiment, as illustrated, all characters from each of the configurations are simultaneously visible on the keypad. When selecting a configuration, the characters corresponding to that configuration illuminate, providing an indication of available characters or symbols to the user. According to another embodiment of the invention, only the characters or symbols corresponding to a selected configuration are shown. Thus, keypad 1300 may have a display similar in appearance to configurations 1302, 1304 or 1306, etc.
It is understood that the various forms of input described above can be combined, according to one embodiment, for added efficiency. For example, enhanced keypad 1300 can detect both voice and lip movement to more quickly isolate the desired symbol. Similarly, lip recognition can be used in conjunction with finger detection (e.g. tip, flat), and so forth.
Lip recognition is particularly useful in public locations with high noise volume. Rather than possibly confusing a voice recognition device, an optical sensor can be provided, such as optical sensor 1428 (

It is understood that the keypad surface maybe covered by a one-piece detecting pad, covering keypad keys, or itself constituting keypad keys. The detecting pad may also be made from a plurality of smaller pads, each pad covering a different key of the keypad or itself constituting a keypad key. It must be noted that the keypad may be constituted from a one-piece sensitive pad, theoretically divided by lines in for example 12 squares, each square being defined as a specific key, according to it location on the keypad.
According to one embodiment, a calibration step, using any of described finger recognition methods, can be used to assign individual fingers, or positions of fingers (e.g. tip, flat) on the pad, to various configurations. This step may involve pressing one, two or more fingers against finger pad 1408, or any one, two or more of the keypad keys, to provide the keypad with data for future detection. It is noted, that according to one embodiment, detecting between two fingers, may be a simple task of isolating the larger or smaller finger, wherein two differently sized fingers are used. This is true for finger portions such as finger's tip and finger flat portions by which the pad is touched. Naturally, alternative embodiments may utilize more sophisticated finger print or finger shape detection means, such as the detection means described above.
According to another embodiment of the invention, finger pad 1408 may be configured as a finger pad input device, similar to the embodiments discussed above. Thus, one may assign characters, symbols or functions to one's fingers and provide input to the system without the need to press the keypad keys (e.g. pointing fingers to keypad keys). Voice and lip recognition can also be employed with the finger pad 1408 to provide added functionality. Similarly, finger pad 1408, in one embodiment, may be excluded from the keypad device 1400 altogether.
With reference to
Notably, one reason for configuring the device, which according to one embodiment separates numbers and letters, is that users typically don't use both letters and numbers simultaneously when typing. In addition, to limit the passing from one mode to another, some characters frequently used in both modes, may be provided on more than one side (e.g. numeric side and alpha side). For example the symbol "−" is provided in key 1407 in numeric configuration and in key 1409 in alpha configuration. In
With continued reference to
Similarly, according to one embodiment, the user can actually speak the desired letter, character or function, rather than provide its location on the key. In addition, a thumb, or other finger, according to one embodiment can be used to correspond to PC or computer functions also provided to the enhanced keypad. It is understood that, according to one embodiment, only one finger, a portion of a finger or a position of that finger, rather than three fingers, is needed to represent the letters on the input device.
As shown in
To other buttons such as 1455, where no letter is assigned to the key, usually three alpha symbols are provided. They are located on top left, middle left and bottom left, on the key. The default may still be the middle left character. It will be selected as described for buttons containing letters. To select on of the other characters or functions, the user may speak for example, the word "UP", for the top left character, or the word "DOWN", for the bottom left one.
Characters and functions in numeric mode are arranged on the right side of the keypad keys. Each key may usually have up to three characters, one in the top right, one in the middle right and one in the bottom right. Numbers from 0 to 9, and other symbols on a standard telephone keypad such as, "*" and "#", may occupy their habitual locations on the keys. They can for example, be placed in the middle right locations on the keys (e.g. 1454). To choose a number or a numeric character, the user first selects the numeric mode with numeric assigned finger as described for alpha mode. If the user does not use any additional recognition means, then the system selects the default character in the middle right position of the key (e.g. "1" on the key 1455). To select the numeric character on the top right or bottom right of the key, the user can use additional recognition means such as voice, by speaking, for example, its location on the key, by using, for example, the words "UP", or "DOWN".
Other functions such as PC commands, may be located on different keys of the keypad, for example, bottom center of the keys (e.g. 1458). To select a command such as a PC command, the user can, for example, press a button by a finger or a portion of a finger that commands are assigned to. If more than one command is assigned to a key, then an additional recognition system as voice such as "UP", "DOWN", can be added to finer recognition system.
The above-mentioned embodiment is a user-friendly system. It has many advantages such as:
It is noted, that according to one embodiment, if the recognition device of this invention does not satisfactorily output the desired letter, number or symbol, the user may select a 'backspace' or error notification key. This key may be 'Bk' key 1458 or perhaps an error notification button, such as button 1460, for example. Thereafter, the input device will provide an alternative selection, which may or may not correspond to the originally intended selection, wherein the user may again select the 'backspace' key, and so forth. According to one embodiment, the 'backspace' key simply removes the previous selection without providing an alternative selection. Rather, the input device may, according to one embodiment, remember the previous selection so that the same error will not be repeated. According to one embodiment of the invention, a spelling checker can be provided to enhance the detection based on the correct spelling of a typed word, etc. For example, if a user is typing a word and the detection device is having difficulty identifying one of the corresponding letters, the letter which completes a correctly spelled word will be chosen according to one embodiment. For this purpose the system may contain a database of words and functions of one or more languages in its memory.

With reference to
According to another embodiment of this invention, enhanced keypad device can alternatively be provided with light sensors or pressure sensing means for finger detection, among other things. Illustratively, with reference to
Light sensors 1502 operate by employing detection in two ways. First, the sensors detect the location of the finger on the keypad, and second they determine the particular size and/or shape of the finger being used. The location of the finger is determined based on intersecting X and Y coordinates of the bi-directional light sensing rays. For example, light sensors can be projected both horizontally and vertically. The horizontal and vertical rays that sense a blocking object, such as a finger, are activated. Thus, the location of the finger is the same location where the activated horizontal and vertical light sensors intersect on the two dimensional pad of the keypad.
The size and/or shape of the particular finger being used is determined based on the number of activated light sensors. A wider or larger finger will naturally activate more sensors, wherein the light sensors are configured with sufficient sensitivity or resolution. Thus, based on a size or shape determination, the particular finger used can be isolated. Once the location and precise finger is identified, such a keypad or input device can operate in a similar fashion to one of the embodiments described above.
Pressure sensing means 1504 are also able to detect the location of the finger and the particular type of finger used. The location is determined based on the pressure mechanism. Namely, the location with the sensed pressure is the location where the finger is pressing. Moreover, a very sensitive pressure sensing device can also determine the precise size of a finger based on the precise area that the pressure is sensed. Similar to the light sensor, differently sized fingers can be detected in such a fashion. Notably, such very sensitive pressure sensing devices are available in the art. For example, U.S. Pat. No. 5,952,585 to Trantzas et al, titled Portable Pressure Sensing Apparatus . . . . describes such a device and is hereby incorporated by reference into this application. Such system can operate in a similar fashion to one of the embodiments described above. It is understood that pressure sensing pad and light sensing means can be used in conjunction, first system determining the location of the finger to determine, for example, the key presses, and second system measuring the finger size, to determine which finger was used.
It is noted that according to one embodiment of the invention, the above described light and pressure sensing means can be configured to operate with other forms of input or detection as well. For example, voice or lip detection can be incorporated for added functionality or accuracy.
According to one embodiment of the invention, the devices utilizing the above described light sensors and/or pressure sensing means are configured without keys, buttons, or similar input signal tools. Indeed, with continued reference to
With reference to
It is understood that the input and recognition devices described herein can be configured with a variety of tools and/or surfaces. For example, according to one embodiment, an input device can be provided with keys, while according to another a touch sensitive display screen is utilized, etc. Similarly, any recognition device can be incorporated, including camera and optical detection, laser detection, and rayon detection. Notably, regardless of the surface, according to one embodiment each of the keys or surface locations can be customized by the user to correspond to different functions, letters, symbols, etc. Should the surface be of a technology that cannot dynamically display the user changes, an overlay can be provided to provide via paper or other material a key imagery that corresponds to the user customization.
With reference to
Referring to
As previously mentioned, characters, functions, symbols, or combination of them can be assigned to scanned portions, positions, or motions of one or more fingers. For example, to two different positions or portions of a finger on a sensitive pad, two group of one or more characters, functions, or symbols can be assigned. The scanning system can be made by thermal, pressure, optical, or any other recognition means.
This method can be used for selecting different group of characters in the enhanced keypad 1400. According to another embodiment of the invention, instead of using different fingers to select different configurations, different portions of a finger can be used to select different configurations. For example, tip portion 1422 a of finger 1422 can be assigned to one certain function and the flat portion 1422 b of finger 1422 can be assigned to a different function. Furthermore, the keys or the buttons of the keypad are configured such that various portions of the user's fingers can be detected. Thus, a user can select the alpha configuration by pressing one of the buttons or keys of the keypad with the tip portion 1422 a and, likewise the user can select the numeric configuration, with the flat portion 1422 b of the same finger.
This system will allow more flexibility and can multiply the assignment possibilities for a user. For example, by pressing a key of the keypad with flat portion 1422 b of finger 1422, a user can select the alpha configuration. He can also select the numeric configuration by pressing a key of the keypad by tip portion 1422 a of the same finger 1422 or another tip portion of another finger, for example 1424. The commands could be selected for example by pressing a button by the thumb, a portion of a finger or both of them.
According to one preferred embodiment of the invention, as mentioned before, by combining keys of a keypad, finger recognition systems, voice/speech recognition systems and arrangements of characters, symbols and functions (hereafter symbols) on the keys of the keypad (e.g. telephone keypad), a user can achieve to isolate one of those symbols by pressing on, or pointing to, a button only one time. As explained in more detail hereinafter, other isolating means as a click system for the keypad keys can be added to above-mentioned combinations.
It is understood that in some embodiments, selecting a symbol may not require all of the above-mentioned character/function selection means—such as voice or finger position or finger shape or fingerprint—but only some or even one of them. For example the combination of above-mentioned means of selecting a symbol may be different for each keypad or a key of a keypad. Thus, for different keypads different arrangements of symbols on the keys may be provided. As such, a key may contain only one or two symbols requiring, for example, one of the selection means to select the desired symbol.
As mentioned before, in the embodiments that employ voice or speech recognition, for choosing a letter, the user pushes a button with the finger or a portion a finger that alpha characters are assigned to, and in the same time he only has to speak the letter desired by him. For all other symbols in alpha configuration he may not have to speak. A symbol shall be selected by default by only pressing the key without speaking. In the numeric configuration the user usually has three possibilities per key. If he does not use his voice the default symbol will automatically be selected. For other numeric symbols on the key, he can use his voice to say for example "up", or "down" or any other voice signal he desires (these voice signals and combinations of assignments to different fingerprints could previously been taught to the machine by one or more users). Preferably, numbers or other numeric symbols used frequently may be used as default choices. In this case the user will rarely use his voice to select a numeric symbol.
The above embodiment permits the user to easily, quickly and naturally enter texts and functions through the telephone keypad.
In still another embodiment of the invention, the keys of the keypad are made from click sensitive pads. A click sensitive pad is configured to respond to two levels of finger pressure. A light pressure generates one response and a heavier pressure generates another response while indicating to the user by means of a click. The click system can be combined with any other recognition system and specially with the ones described before. For example in
The above-mentioned system is also useful to make selection of symbols without using a user's voice. A group of symbols are available on a key. A user can assign to each finger a number of those symbols. A specific motion of a finger on the key or the portion of the finger by which the key is pressed, may select the symbol desired by a user. For example in
Instead of finger portion by which the button is pressed, a click system can be added to the key. In this case, for example after a user selects a column 2412 by a corresponding finger, he can push it with his finger in any position or portion. He can select the letter "X", by pressing the button slightly. If he desires to select the "+" symbol, he must press the button with more pressure to click the button.
In still another embodiment of the invention,
To ease the user's input of the symbols of a key, they may be arranged in different rows on that key. In the example of
A middle row contains, for example, two symbols. For choosing one of those symbols different methods can be used. Left side symbol can be assigned to the tip portion of a finger and the right side to the tip portion of another finger both touches without clicking the button. Voice inputs as "left" or "right" can also be used to select one of the symbols combined with the pressing of the button by any finger in, for example, upward (e.g. tip) position.
Lower row comprises two more characters. To select a symbol of this row, the user may use the same system as the second row but with adding a click of the button by pushing it stronger. It is appreciated to those skilled in the art that many variations of the combinations of the selection means can be employed without departing from the present invention.
With reference to
Thus, many of the benefits of the present invention can be employed to provide an improved keypad system that is versatile, compact and user friendly. As mentioned before, using a finger recognition system for entering symbols through the telephone-type keypad or selecting a configuration of symbols (e.g. alpha, numeric, function), a user can use his fingerprints or finger characteristics according to at least the following principles separately or combined;
It is understood that the fingerprint recognition usage can be applied to the fingers of both hands. In addition, voice, lip and other recognition systems may be combined with finger recognition systems mentioned above.
As mentioned before, for speaking silently, for example the letters, a microphone could be arranged in front of the user's mouth. Another solution is to provide a commercially available microphone in user's ear permitting to input his voice through vibration of his ear bone.
The above mentioned systems of input may be integrated in many devices such as mobile and fix telephones, PDAs, computers, laptops, remote controllers of TVs or other electronic devices, faxes, etc. In addition, independent input devices according to systems described before may be manufactured separately and be used as external input devices for above mentioned products.
The system may include one or more databases of words in different languages. A predictive word recognition system may also be combined with the system to make the entry of a word possible before entering it entirely. This system may allow an automatic selection of the desired word by the machine, mostly before ending to enter it entirely even without the need of the user interference. This is possible, because by selecting individually a character or a symbol through this system (e.g. character by character), and the very small numbers of selection of corresponding words for keys pressed, it will be easy to determine the desired word before finishing to enter it entirely.
Even if the user enters a wrong letter of a word or the machine fails to identify a given letter, since in most cases other letters of the word are entered correctly, the predictive word recognition system can automatically correct the wrong letter.
It is understood that instead of speaking a letter the user can speak a word while pressing the corresponding buttons. In this case the databases mentioned before will be used to select the desired letter by a word recognition system. The end of a word can be determined by many symbols or functions such as ".", ";", space, enter command, etc.
It is also understood that the sensitive keypad can be made either from one pad which is combined with all the keys, or a plurality of separate smaller pads combined with each key (e.g. twelve separate pads for twelve keys of a keypad).
According to yet another embodiment of the invention, one or more of the above-mentioned devices, such as finger pad detection device 800 or enhanced keypad 1400, can be configured to operate with a miniature display screen or communication/computer card. Such a screen or card could comprise a flexible plastic LCD or similar device for the display. It is understood, of course, that the above mentioned input devices can be employed to operate with other devices, in addition to the miniature display screen or communication/computer card described herein. For example, enhanced keypad 1400 can be configured as part of a wrist watch phone, a computer, a PDA device, etc. It is also understood that such LCD may also be used for any device that needs to have an LCD, such as mobile phones. The communication between them may be wireless.
With reference to
Furthermore, multi sectioned LCD pad 1600 comprises a hinge portion 1616 for folding, the pad in half to the size of a credit card, for example. It is noted that, according to another embodiment, LCD pad can be extended outward and inward rather than folded, etc. Notably, according to one embodiment, the entire hinge portion of hinge 1616 is situated on the rear portion of pad 1600 so that the front LCD portion 1602 appears flat for enhanced image visibility, etc. With continued reference to
According to one embodiment, rear enhanced keypad portion 1612 operates in the same manner as keypad 1500 (
According to one embodiment of the invention, LCD pad 1600 can operate as a PDA, a wrist watch PDA, a computer, an interactive newspaper, etc. Illustratively, LCD pad 1600 can be attached to (or telecommunicate with) a miniature computer device for an added LCD display screen, as well as added input means via enhanced keypad 1612, for example. Alternatively, the card may be employed as a PDA for use while simultaneously positioned on one's wrist as a watch.
Alternatively, the card may be employed as a functional LCD display to add on to telephones, cellular phones or other devices, such that interaction with the device via the LCD pad is possible. For example, when dialing a computer automated system via a phone, LCD pad 1600 can be configured to display any computer menus or other automated selections on the LCD. This avoids the hassle of pressing numerous phone keys in order to get the desired selection or location. Moreover, LCD pad 1600 can provide added voice messaging and other computerized features to a phone or other communication device.
It is understood that LCD device of
In yet another embodiment external LCDs may be available in many places, such as offices or restaurants. Carriers of, for example, mobile phones with LCD size limitations, can use this available external LCDs found everywhere. In one embodiment, the user may enter a secret code, known by his phone, in the external LCD to permit communications between that LCD and his phone. After usage the user decodes the external LCD. This system limits the communication to only desired LCD and avoids the connection with other LCDs available nearby.
With reference to
Large LCD panel 1700 can be folded to approximately a forth of its size via folding hinges 1706 and 1708. Notably, view 1702 illustrates large LCD panel 1700 in a half-folded view. Furthermore, view 1704 illustrates LCD panel 1700 in a fully folded view. It is understood that large LCD panel 1700 can be configured with more or less hinge mechanisms to further increase or decrease the size and compactness of the device.
According to one embodiment of the invention, LCD panel 1700 can be configured to operate as a digital newspaper. Thus, individuals can use LCD panel 1700 to download digitized news from one or more news sources and thereafter read the news or other desired information. Such a device is advantageous since news can be continuously updated throughout the day and the format and content of the news can be customized by the user.
For example, one user may program the LCD panel 1700 to only download sports news from three particular sources. Another user can only view local news, and so forth. It is understood that LCD panel 1700 can display information in addition to the information traditionally provided by newspapers. Indeed, a digital environment provides means for features that are unavailable with the traditional newspaper format. According to one embodiment of the invention, the above-described downloading, uploading and updating is accomplished via the Internet. Similarly, according to one embodiment, any of the devices described herein can be configured to upload or download data via the Internet.
According to one embodiment, LCD panel 1700 is provided to users at various download stations. Rather than waiting a possibly extended period to download the desired news. Kiosks, or similar sites, can be introduced, wherein individuals pick up and drop off their LCD panel devices for faster downloading. Such locations can have bandwidth or other technology not available to the average user. According to one embodiment, such LCD panel device can be the property of a news corporation, wherein individuals borrow or rent the devices for digital news. Such embodiments enable the majority of downloading to occur at the Kiosk and minimal, non-intensive downloading can occur through other means, such as wireless technology, to update the news, if needed, while the LCD panel is in the user's possession.
This system and method has many advantages. Kiosks may permanently be updated with the last versions of any news agency's information and other publications. A user may possess a card (hereafter "Newscard"). The LCD device, (hereafter "Newslcd"), can be borrowed from a kiosk using Newscard. It may be returned to that kiosk or any other kiosk as well. Newscard will be updated to show that its owner has a Newslcd with him. The user can ask the kiosk owner to provide him with a copy of any publication he desires. Since the publication is only required to be locally copied, the procedure will be practically instantaneous.
For payment, the user either uses his Newscard or another payment system. If the user uses his Newscard, he may receive a monthly statement for all publications he has purchased during that period. If the user does not want to carry the Newslcd permanently, he simply can deposit it in the nearest kiosk and his Newslcd will be updated accordingly, showing that he does not possess a Newslcd. The Newslcd may contain a floppy disk accommodation, permitting the user to remove the diskette containing his publications. At any moment the usr can access to another kiosk to borrow another Newslcd. It must be noted that the diskette maybe of any kind and it could be the property of any party. Newslcd, may be a large flexible, for example plastic, LCD. It may comprise a reduced keypad for functions such as "next page", or zoom.
According to one embodiment, the large LCD panel can be designed without hinges, such that no folding is possible. Such a device may comprise plastic LCD technology, as mentioned above, for added flexibility.
It is noted that, according to one embodiment of the invention, large LCD pad 1700 can also be a fully operational computer or similar device. For example, the LCD display portion can operate both as a display screen and as an input device. Notably, the input device of

With reference to
Keypad device 2002 or display screen 2004 can also be provided with a camera 2006, microphone 2010, and earpiece 2008, in order to employ the recognition methods described above. According to one embodiment of the invention, for example, voice recognition can be employed. Illustratively, one type of voice recognition may operate while the user is typing characters or words into the keypad device and simultaneously speaking those words to be interpreted via voice recognition. The accuracy of the recognition is improved since the user is also typing all or part of the words being spoken. According to one embodiment, a space or period key, or any other symbol, can be added to the keypad to signal the start of a new word. It is also understood, that the voice recognition described above can be employed via lip, face, or other forms of recognition as well. Thus, according to one embodiment, a user can use lip recognition to pronounce entire words as well.
With reference to
At step 3304 the system determines which mode of operation has been selected, based on the finger pressed. If Alphabet mode is selected the system goes to step 3306 to begin the alphabet procedure as illustrated in
As illustrated in
If the voice or lip indication at step 3322 is not a pronouncement of an alphabet but a predefined command, such as "UP" or "DOWN" the system assigns the character that is located on the upper or lower portion of the button. For example, if the user pronounces "UP" in combination with button 1455 in
At step 3322, if the system does not hear a sound or recognize the movement of the lip or other facial expression, but a button is pressed by the user, the system goes to step 3334 and selects a corresponding default character symbol or function. For example, with reference to
If the numeric mode has been selected by the user, the system goes to step 3350 as illustrated in
For example, if button 1454 is pressed in combination with the utterance of the word "UP" the system at step 3356 selects the corresponding "%" sign. If however, the system does not recognize a sound or does not hear a predefined sound it goes to step 3364 and returns to step 3300. If on the other hand, no word is uttered the system goes to step 3358 and the default character is selected. For example numeral "2" in
Finally, if the user selects a command procedure the system goes to step 3370, and at step 3372 detects whether the user has uttered a word or moved his/her lips or other facial indication indicating a predefined signal, such as uttering the word "UP" or "DOWN," or a not predefined word, as described previously. The system at step 3376 in response to the combination of the uttered predefined word and pressing a button selects a corresponding command or function. If however, the system does not recognize a sound or does not hear a predefined word it goes to step 3380 and returns to step 3300. If no word is uttered or no lip or facial expression movement has been recognized, the system goes to step 3378 and selects a default "command". The system then exits at step 3380 and goes back to step 3300 for the next action by the user.
Thus, while there have been shown and described and pointed out fundamental novel features of the invention as applied to alternative embodiments thereof, it will be understood that various omissions and substitutions and changes in the form and details of the disclosed invention may be made by those skilled in the art without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto. It is to be understood that the drawings are not necessarily drawn to scale, but that they are merely conceptual in nature.

That's an oxymoron...LOL
Nah. It's pretty much stating the obvious. I thought the guy was serious that's why I bothered to post about it. Apparently he was making a joke. Maybe that's his cover up. Heh heh
Will someone please get discoweasel a taco?
a fish taco of the verical type, ill have one as well
uh... I'll comment to say no comment -_-
What?? Don't be a pansy lol you know I'm just having fun. Are you keeping that trophy safe? Ha
I am still desiring a taco . . .
Make your own taco Lol. Or ask Caleb to share his taco trophy with you.
When I was a kid (maybe 10 or 12), I was playing another kid and he thought that if he could put me in checkmate the turn after I did then it was a stalemate!
LOLLLL... that is just too funny. It makes us all feel a little smarter I guess? Well I hope you taught him the correct way to play :)
Yes now go make your move. It's been your turn for hours now lol
Haha, you really think I was serious, don't you. And yes, the trophy is virtually protected.
Yes I thought you were serious, haven't we had this discussion already. lol.
I saw someone say this on chess.com. I thought it was funny: "It seems like when I put my opponent in checkmate, they lose; but when they do it to me, I lose."
I have theory. It is mine and mine alone. No one elses. My theory is that dinosaurs are very small at the head end, get very large towards the middle and then get very small towards the tail end again
In blitz it would be a stalemate if nobody realizes the check/checkamte in the beginning then the move after the other opponent checkmates and stops the clock, but then you see that that was an illegal move, so then it's a draw...
Very smart!! I've never thought of it that way! I mean, who would ever think that!?!? That man/woman must be a true genius!!!!

Jason, the front desk manager, went far beyond what we expected to ensure we had a great stay ! He is a HUGE assett to this great hotel !

Nice hotel, but some hiccups along the wayPosted Jul 14, 2016
The staff was prompt and friendly at check-in. However, as I got to my room, I quickly realized that it had not been cleaned. I called down to the front desk, and they said they would send someone up right away, but the room had still not been cleaned even after I returned from dinner. Fortunately, after I complained to the front desk again, they gave me a new room and comped breakfast for me. Overall, it was a nice hotel, but I was disappointed that it took them so long to resolve the situation with my dirty room.

Room was clean and comfortable. The drain in the shower didn't drain well, and I felt for the cost and how nice the hotel is they would offer more tv channels. I would say there again though. thank you
