PREDICTIVE INFORMATION FOR FREE SPACE GESTURE CONTROL AND COMMUNICATION

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.
