Malik, Shahzad, Ranjan, Abhishek and Balakrishnan, Ravin (2005): Interacting with large displays from a distance with vision-tracked multi-finger gestural input. In: Proceedings of the 2005 ACM Symposium on User Interface Software and Technology 2005. pp. 43-52.

We explore the idea of using vision-based hand tracking over a constrained tabletop surface area to perform multi-finger and whole-hand gestural interactions with large displays from a distance. We develop bimanual techniques to support a variety of asymmetric and symmetric interactions, including fast targeting and navigation to all parts of a large display from the comfort of a desk and chair, as well as techniques that exploit the ability of the vision-based hand tracking system to provide multi-finger identification and full 2D hand segmentation. We also posit a design that allows for handling multiple concurrent users.

Malik, Shahzad and Laszlo, Joe (2004): Visual touchpad: a two-handed gestural input device. In: Proceedings of the 2004 International Conference on Multimodal Interfaces 2004. pp. 289-296.

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.
