This paper presents the Visual Touchpad, a low-cost vision-based input device that allows for fluid two-handed interactions with desktop PCs, laptops, public kiosks, or large wall displays. Two downward-pointing cameras are attached above a planar surface, and a stereo hand tracking system provides the 3D positions of a user's fingertips on and above the plane. Thus the planar surface can be used as a multi-point touch-sensitive device, but with the added ability to also detect hand gestures hovering above the surface. Additionally, the hand tracker not only provides positional information for the fingertips but also finger orientations. A variety of one and two-handed multi-finger gestural interaction techniques are then presented that exploit the affordances of the hand tracker. Further, by segmenting the hand regions from the video images and then augmenting them transparently into a graphical interface, our system provides a compelling direct manipulation experience without the need for more expensive tabletop displays or touch-screens, and with significantly less self-occlusion.
