Abstract
A hand of a user may be detected in free space, where a plurality of surface points are determined and include a center area surface point and at least two surface points of the plurality of surface points located on a periphery of the surface of the hand. A curve extending through the plurality of surface points may be determined based on a position of a curvature. The plurality of surface points are processed to determine if the plurality of surface points of the detected hand are arranged in at least one of a substantially concave area relative to the sensor, and/or a substantially convex area relative to the sensor. The detected hand may be identified as a palm or back of the hand based on the processing of the plurality of surface points.
