Zooming Touch Panel


Information devices with a touch panel are often seen in our life, but a touch panel is difficult to operate precisely as well as it is unsanitary.

We developed a touch panel with new interface, which measures three dimensional position of the finger near the panel using two cameras, displays a cursor on the panel, and zooms the screen according to the finger depth.
