Patent ID: 8811719

Claim:
A system comprising: at least one device processor, and including a machine readable storage device storing executable instructions, the executable instructions configured, when executed, to cause the at least one device processor to: initiate access to a database including a plurality of database objects, each database object associated with a respective one of a plurality of predefined three-dimensional (3-D) models, each of the 3-D models simulating an appearance of a corresponding one of a plurality of predetermined 3-D items; receive 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; generate an integrated 3-D model based on incrementally aggregating temporally sequential 3-D representations of the 3-D positioning of the at least one hand in accordance with the received 3-D spatial image data, selecting portions of the received 3-D spatial image data for aggregation based on comparing a threshold time value with numbers of instances of time spent by the at least one hand within a plurality of 3-D regions during the free-form movements; and select at least one of the predetermined 3-D items, based on accessing the database and determining at least one of the database objects that is associated with at least one of the predefined 3-D models that matches the integrated 3-D model.
