Claim 0:
1. A non-transitory computer readable medium comprising computer readable code executable by one or more processors to:
obtain image data for a finger and a target surface;
identify a touch region on the target surface where the finger makes contact with the target surface;
determine a directional 3D ray consistent with a pointing direction of the finger in the image data;
estimate a target region based on a point in space at which the directional 3D ray passes through the target surface, wherein the point in space is determined based on an estimated depth of the target surface, and wherein the target region is different from the touch region;
determine a touch status based on the estimated depth of the target surface; and
trigger an event based on the touch status, wherein the event is based on the target region.
