Touchscreen technology may be one of the newer ways of interacting with a personal computer, but researchers at MIT (Massachusetts Institute of Technology) are already working on new ways of interactivity including gestural computing.
The technology is reminiscent of what was used by Tom Cruise in the movie Minority Report in which nothing more then hand motions was used to manipulate onscreen objects. Known as BiDi (for Bi-Directional), the display screens essentially have digital cameras and optical sensors behind the screen which can recognize not only movement but also depth which is great as it allows objects to be manipulated “in and out” of the screen. Although the new screens are continually toggling between image capture and image display, to the user, it appears as though only the image is viewable.
This is cool technology and if you’re interested in learning more about it as well as its future direction, be sure to check out the MIT website.
