Abstract:
1. A system comprising: a spatial input subsystem that includes at least one sensing device that detects 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, including a processor, communicatively coupled to the spatial input subsystem and that authenticates the plurality of users by identifying a plurality of user identities-based on physical characteristics of the plurality of hands of the plurality of users, the plurality of user identities corresponding to the plurality of users, executes a multi-user shared display session that provides the plurality of authenticated users with concurrent control of a display on the display screen, and controls how at least one resource associated with the display is shared between the plurality of authenticated users during the multi-user shared display session, wherein: the at least one resource associated with the display comprises a screen space of the display screen; and the shared display subsystem controls how the screen space of the display screen is shared between the plurality of authenticated users by dividing the screen space of the display screen into a plurality of non-overlapping screen zones, and granting, based on a shared session heuristic that specifies a set of screen space allocation rules governing how the screen space is allocated among the authenticated users, each authenticated user within the plurality of authenticated users control of a different screen zone within the plurality of non-overlapping screen zones.
