Assignee: ULTRAHAPTICS IP TWO LIMITED
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 20:
21. A non-transitory computer readable storage medium impressed with computer program instructions to determine a gesture performed by the at least a portion of a hand in three dimensional (3D) sensory space, which instructions, when executed on a processor, implement actions 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 as an output, the gesture as determined.
