Non-linear navigation of a three dimensional stereoscopic display

摘要

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.

1. A method for navigating a three dimensional (3D) stereoscopic scene displayed via a 3D stereoscopic display system, the method comprising:
enabling a user head tracking navigational mode of the 3D stereoscopic display system; establishing a reference point of view (POV), wherein the reference POV comprises a reference user head position and a reference user head orientation; tracking user head POV, wherein said tracking monitors user head positional displacements and user head angular rotations relative to the reference POV; and adjusting, in response to said tracking, a camera POV used to render the 3D stereoscopic scene, wherein said adjusting is 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, and wherein the non-linear mapping comprises:
a mapping of user head positional displacements relative to the reference POV to translational movements in the camera POV; anda mapping of user head angular rotations relative to the reference POV to rotations in the camera POV.
