Researchers from the National Taiwan University have unveiled the i-m-Top a rear-projection, interactive, dual-resolution tabletop system, which can turn the top of an ordinary desk into a 120×80cm touchscreen display. According to the researchers at the university’s Graduate Institute of Networking and Multimedia, the system makes use of infrared sensors to detect the motions or movements of the user’s hands to enable interactive functions. This runs with two rear projectors, one for blanket coverage of the entire tabletop, and the other one for a According Yi-Ping Hung, director of the graduate institute, this system has taken 4 years to develop and will provide a much cheaper solution for touch screen displays. Its target audience are professional workshops and high-level executives. Hung said the institute may

Scientists at Microsoft Corporation’s lab in the UK have developed a prototype interactive touch-screen that can see and recognize one’s hand movements and anything near its surface. The screen acts as a two-handed touch interface and a crude infrared camera. Users can operate the display with both hands, in a similar manner to the display in the film Minority Report, say its developers. However, the screen can also recognise particular hand gestures as well as objects placed within a centimetre of its surface, they say. “It can sense much more than fingers, and is essentially a low resolution scanner and camera,” said lead researcher Shahram Izadi, adding that the screen can even communicate wirelessly with other devices nearby using the same infrared technology it uses
