Abstract
Techniques for detecting a hand of a user and a pose of the hand are described herein. In some instances, as a user interacts with a computing system through various hand signals, the hand of the user and pose of the hand (e.g., position and orientation) may be detected. To detect a hand, a point set may be analyzed to identify local extremum points (e.g., peaks and valleys) along an outer boundary of the point set. The local extremum points may then be used to identify a potential hand segment including one or more potential finger segments and/or a potential palm segment. When the potential hand segment satisfies one or more criteria, a hand may be detected. To detect a hand pose, an observed pose of the hand segment may be compared to one or more hand pose models.
