1. A method of determining a gesture performed by the at least a portion of a hand in three dimensional (3D) sensory space, the method comprising:
determining a variance between a point on a set of observation information based on an image captured at time t1 and a corresponding point on at least one of a set of 3D capsules fitted to another set of observation information based on an image captured at time t0 by:
pairing point sets from points on a surface of the observation information with points on the 3D capsules, wherein normal vectors to points on the set of observation information are parallel to normal vectors to points on the 3D capsules; and
determining the variance comprising a reduced root mean squared deviation (RMSD) of distances between paired point sets; and
responsive to the variance, adjusting the 3D capsules; and
determining a gesture performed by the at least a portion of a hand based on the 3D capsules as adjusted; and
providing the gesture determined.
