OBJECT TRACKING SYSTEM AND METHOD

摘要

User interface apparatus for a computer system, comprises: a touch surface having an internal face and a touch face; cameras placed about said touch face and arranged to image the touch face including the surface itself and a volume extending outwardly from the surface on the touch face; and an illumination unit that illuminates the touch side. The illumination unit illuminates separately a) a relatively thin first volume close to the touch surface for touch control—the touch volume, and b) a relatively deep second volume extending away from the first volume for three-dimensional hand or body gesture control— the depth volume, the separate illuminating providing for separate imaging by the cameras of the touch and depth volumes.

1. User interface apparatus for a computer system, comprising:
a touch surface having an internal side and a touch side; a plurality of cameras placed about said touch surface and arranged to image said touch side; and an illumination unit configured to illuminate said touch side of said touch surface, said illumination unit configured to illuminate separately a) a relatively thin first volume close to said touch surface for touch control of said user interface, and b) a relatively deep second volume extending away from said first volume for three-dimensional hand or body gesture control of said user interface, said separate illuminating providing for separate imaging by said cameras of said first volume and said second volume.
