Inferring spatial object descriptions from spatial gestures

A method comprising:

• receiving three-dimensional (3-D) spatial image data associated with at least one arm motion of an actor based on free-form movements of at least one hand of the actor, based on natural gesture motions of the at least one hand;
• determining, via at least one device processor, a plurality of sequential 3-D spatial representations that each include 3-D spatial map data corresponding to a 3-D posture and position of the at least one hand at sequential instances of time during the free-form movements, based on the received 3-D spatial image data;
• and
• generating, via at least one device processor, an integrated 3-D model based on incrementally integrating the 3-D spatial map data included in the determined sequential 3-D spatial representations and comparing a threshold time value with model time values indicating numbers of instances of time spent by the at least one hand occupying a plurality of 3-D spatial regions during the free-form movements.

A computer program product that includes a machine readable storage device tangibly embodying executable instructions that, when executed, cause at least one device processor to:

• receive three-dimensional (3-D) spatial image data associated with at least one arm motion of an actor based on free-form movements of at least one hand of the actor, based on natural gesture motions of the at least one hand;
• determine a plurality of sequential 3-D spatial representations that each include 3-D spatial map data corresponding to a 3-D posture and position of the at least one hand at sequential instances of time during the free-form movements, based on the received 3-D spatial image data;
• and
• generate, via a spatial object processor, an integrated 3-D model based on incrementally integrating the 3-D spatial map data included in the determined sequential 3-D spatial representations and comparing a threshold time value with model time values indicating numbers of instances of time spent by the at least one hand occupying a plurality of 3-D spatial regions during the free-form movements.
