Shape trace gesturing
First Claim
Patent Images
1. A data-holding subsystem holding instructions executable by a logic subsystem to:
- render an interactive interface for display on a display device;
receive a virtual skeleton including a plurality of joints, the virtual skeleton providing a machine readable representation of a human observed with a depth camera; and
identify a two-handed gesture as one of a plurality of different recognizable two-handed action selection gestures, each of the different recognizable two-handed action selection gestures including two different hands tracing different portions of a same traced shape, each traced shape being associated with a different action executable within the interactive interface.

Abstract
Gestures of a computer user are observed with a depth camera. A trace gesture of the computer user is identified and an action performable within an interactive interface is selected based on the shape of the trace gesture.

13. A method of executing a spell-casting game on a computing system, the method comprising:
-
identifying a two-handed gesture of a game player as one of a plurality of different recognizable two-handed gestures, each of the different recognizable two-handed gestures including two different hands tracing different portions of a same traceable shape, each traceable shape being associated with a different spell castable within the spell-casting game by a player character controlled by gestures of the game player; and responsive to identifying a conclusion of the two-handed gesture, casting the spell associated with the traceable shape within the spell-casting game. - View Dependent Claims (14, 15, 16)

17. An entertainment system, comprising:
-
a peripheral input to receive depth images from a depth camera; a display output to output an interactive interface to a display device; a logic subsystem operatively connectable to the depth camera via the peripheral input and to the display device via the display output; a data-holding subsystem holding instructions executable by the logic subsystem to; receive from the depth camera one or more depth images of a world space scene including a computer user; model the computer user with a virtual skeleton including a plurality of joints; recognize a two-dimensional projection of a path of a left hand joint of the virtual skeleton and a path of a right hand joint of the virtual skeleton tracing different portions of a same traced shape onto a tracing plane; translate the two-dimensional projection as a selected one of a plurality of different two-handed action selection gestures, each two-handed action selection gesture associated with a different action performable within the interactive interface; and responsive to identifying completion of the selected two-handed action selection gesture, perform within the interactive interface the action associated with the selected two-handed action selection gesture.
