Gestural object selection

摘要

A posture for a user is derived and used in conjunction with a known physical location of a tangible object or a presented virtual object to determine when the user selects at least a portion of the object. The derived posture comprises a model having a user origin and a gestural terminus, from which a designation vector intersecting with the selected object is determined. The designation vector may extend from a user origin of the dominant eye through a gestural terminus comprising a tip of an outstretched finger. For example, the user may point to a chair in the room to select the physical chair, or point to a picture of a chair presented via a display device to select the picture.

1. A system comprising:
a processor; a projector coupled to the processor and configured to generate structured light within an environment; a camera coupled to the processor and configured to capture at least a portion of the structured light within the environment; memory, accessible by the processor; a spatial analysis module stored in the memory and configured to generate spatial data about one or more objects within the environment; and a tracking and control module stored in the memory and configured to:
identify an object within the environment as a user based at least in part upon the spatial data;derive a posture of the user based at least in part upon the spatial data;determine a physical location of a user origin associated with the user relative to the posture of the user;determine a location of a gestural terminus of the user based at least in part on the posture of the user;determine a designation vector based at least in part upon the physical location of the user origin and the location of the gestural terminus, a magnitude of the designation vector being proportionate to a distance between the physical location of the user origin and the location of the gestural terminus;determine a portion of a representation of a second object that corresponds to the designation vector; anddesignate the portion of the representation of the second object as a selection made by the user.
