Non-linear navigation of a three dimensional stereoscopic display

Abstract

Systems and methods for navigating a 3D stereoscopic scene displayed via a 3D stereoscopic display system using user head tracking. A reference POV including a reference user head position and a reference user head orientation may be established. The user head POV may be tracked, including monitoring user head positional displacements and user head angular rotations relative to the reference POV. In response to the tracking, a camera POV used to render the 3D stereoscopic scene may be adjusted based on a non-linear mapping between changes in the camera POV and the user head positional displacements and user head angular rotations relative to the reference POV. The non-linear mapping may include a mapping of user head positional displacements relative to the reference POV to translational movements in the camera POV and a mapping of user head angular rotations relative to the reference POV to rotations in the camera POV.
