Patent ID: 8522308

Claim:
A system comprising: a spatial input subsystem configured to detect hand gestures made by a plurality of hands of a plurality of users within a physical user space associated with a display screen; and a shared display subsystem communicatively coupled to the spatial input subsystem and configured to authenticate the plurality of users by identifying a plurality of user identities based on characteristics of the plurality of hands, the plurality of user identities corresponding to the plurality of users, create associations between the plurality of hands and the plurality of user identities, track a continuity of each hand within the plurality of hands to ensure that the associations between the plurality of hands and the plurality of user identities remain accurate, execute a multi-user shared display session that provides the plurality of authenticated users with concurrent control of a display on the display screen through the detected hand gestures, and control, based on a shared session heuristic, how at least one resource associated with the display is shared between the plurality of authenticated users during the multi-user shared display session.
