摘要
Techniques are described for projecting content onto a display surface and for analyzing the hand of a user that is placed over the display surface, such as when the user is making a command gesture. Based on the location and known shape of the display surface, a surface depth map is calculated corresponding to the display surface. Points of the calculated surface depth map are then subtracted from respective points an observed depth map to produce a foreground depth map corresponding to the user hand. The hand may be further characterized and tracked based on the foreground depth map.
