Operations in a Three Dimensional Display System

摘要

System and method for invoking 2D and 3D operational modes of a 3D pointing device in a 3D presentation system. A 3D stereoscopic scene and a 2-dimensional (2D) scene are displayed concurrently via at least one stereoscopic display device. A current cursor position is determined based on a 6 degree of freedom 3D pointing device. The cursor is displayed concurrent with the 3D stereoscopic scene and the 2D scene, where the cursor operates in a 2D mode in response being inside a specified volume, where, in the 2D mode, the cursor is usable to interact with the 2D scene, and where the cursor operates in a 3D mode in response to being outside the specified volume, where, in the 3D mode, the cursor is usable to interact with the 3D stereoscopic scene.

主权项

1. A non-transitory computer accessible memory medium that stores program instructions executable by a processor to implement:
display a 3-dimensional (3D) stereoscopic scene via at least one stereoscopic display device; display a 2-dimensional (2D) scene via the at least one stereoscopic display device concurrent with display of the 3D stereoscopic scene, wherein the entire 2D scene is displayed at zero parallax; determine a current position of a cursor with respect to the at least one stereoscopic display device based on a position of a 6 degree of freedom (6DOF) 3D pointing device with respect to the at least one stereoscopic display device; and display the cursor via the at least one stereoscopic display device concurrent with display of the 3D stereoscopic scene and the 2D scene; wherein the cursor operates in a 2D mode in response to the current position being inside a specified volume proximate to the at least one stereoscopic display device, wherein the specified volume is bounded by a plane parallel to a screen of the at least one stereoscopic display device, wherein the specified volume is on the screen side of the plane, and wherein, in the 2D mode, the cursor is usable to interact with the 2D scene; and wherein the cursor operates in a 3D mode in response to the current position being outside the specified volume proximate to the at least one stereoscopic display device, wherein, in the 3D mode, the cursor is usable to interact with the 3D stereoscopic scene.
