The extended desktop system for real world computing using camera images

In recent years, many studies on supporting human works in the real world have been done by using augmented reality (AR) technologies. At the same time, many studies on supporting human works on computers have been done by using the computer desktop environment. By combining these technologies, we can build an environment supporting human works both in the real world and on computers. Based on this consideration, we propose an extended desktop environment by integrating conventional desktop environments with AR technologies. In our implemented system, a user can use the real space through images captured by a CCD camera equipped with a computer. In addition, the user can put icons virtually into the real space and use external hardware such as a printer through the picture provided by the camera images.
