Abstract:
The technology disclosed relates to simplifying updating of a predictive model using clustering observed points. In particular, it relates to observing a set of points in 3D sensory space, determining surface normal directions from the points, clustering the points by their surface normal directions and adjacency, accessing a predictive model of a hand, refining positions of segments of the predictive model, matching the clusters of the points to the segments, and using the matched clusters to refine the positions of the matched segments. It also relates to distinguishing between alternative motions between two observed locations of a control object in a 3D sensory space by accessing first and second positions of a segment of a predictive model of a control object such that motion between the first position and the second position was at least partially occluded from observation in a 3D sensory space.

Claim (Index 15):
A system enabling simplifying updating of a predictive model using clustering observed points, comprising:\n at least one camera oriented towards a field of view; a gesture database comprising a series of electronically stored records, each of the records relating a predictive model of a hand; and\n an image analyzer coupled to the camera and the database and configured to: \n observe a set of points in a three-dimensional (3D) sensory space using at least one image captured by the camera; \n determine surface normal directions from the points; \n cluster the points by their surface normal directions and adjacency; \n access a particular predictive model of the hand; \n match the clusters of the points to segments of the predictive model; and \n use the matched clusters to refine positions of matched segments.
