Three-Dimensional Tracking of a User Control Device in a Volume Using Position Sensing

摘要

Tracking objects presented within a stereo three-dimensional (3D) scene. The user control device may include one or more visually indicated points for at least one tracking sensor to track. The user control device may also include other position determining devices, for example, an accelerometer and/or gyroscope. Precise 3D coordinates of the stylus may be determined based on location information from the tracking sensor(s) and additional information from the other position determining devices. A stereo 3D scene may be updated to reflect the determined coordinates

主权项

1. A system, comprising:
a display configured to display a stereoscopic three-dimensional (3D) scene within a virtual space; a user control device configured to manipulate objects within the stereoscopic 3D scene, wherein the user control device includes one or more position sensors, and at least one visually detectable point; at least one tracking sensor configured to track the at least one visually detectable point in a physical space; and a processing subsystem configured to:
provide the stereoscopic 3D scene to the display;receive first location information for the at least one visually detectable point from the at least one tracking sensor;receive second location information from the one or more position sensors of the user control device;determine a position and an orientation of the user control device based on the first and second location information; andprovide an updated stereoscopic 3D scene to the display based on the determined position and orientation of the user control device in the physical space, wherein the updated 3D stereoscopic scene in the virtual space correlates to the physical space.
