initial evaluation of a bare-hand interaction technique for large displays using a webcam
dTouch is a novel 3D pointing system that allows interaction with large displays from the use of a single webcam. An initial evaluation demonstrating the feasibility of our pointing technique is presented. We compared our prototype with a popular 2D pointing technique, used in the EyeToy game for the PlayStation console, in a usability study. Result shows that the two techniques are comparable, each with its pros and cons. We concluded that it is possible to use our technique and a webcam to allow interaction with large displays. With further development, our technique can serve as a basis for the design of the next generation interactive monocular vision systems, due to the added flexibility to the user's location.
