A braille writing training device with voice feedback

A device incorporating both voice feedback and tactile sensation has been developed to help blind children practice the use of a Braille stylus. A microcomputer and voice-synthesis LSI are used to give voice feedback, and a switch under each hole representing a Braille dot is used to give tactile feedback when the stylus is inserted in a hole. A switch is pressed by the user to hear the voice feedback. A one-cell prototype was used to gather feedback from potential users. Four improvements were identified from this feedback and applied to a six-cell version of the device. Testing of the six-cell device by six school children revealed that, although the device received positive scores for four aspects, further improvements are necessary.
