摘要： Techniques are disclosed relating to the transmission of data based on a polarization of a light signal. In some embodiments, data may include 3D video data for viewing by a user. Systems for transmitting data may include a display device and a device for switching the polarization of a video source. Systems for receiving data may include eyewear configured to present images with orthogonal polarization to each eye. In some embodiments, the rate of switching of the polarization switcher may introduce a distortion to the optical data. A Pi-cell device may be used in some embodiments to reduce distortion based on switching speed. In some embodiments, polarization switchers may introduce a distortion based on the frequency of transmitted light. In some embodiments, optical elements including in the transmitting or receiving devices may be configured to reduce distortions based on frequency.

摘要： In some embodiments, a system and/or method may operate a liquid crystal device. The method may include increasing a voltage provided to a driven level to a liquid crystal addressable element of the liquid crystal device. Said increasing may be performed over a time period greater than 1 ms. The liquid crystal addressable element may be in a driven state at the driven level. The method may include reducing the provided voltage to a relaxed level. The liquid crystal addressable element may be in a relaxed state at the relaxed level. Said increasing the voltage over the time period to the driven level may result in a reduced acoustical noise associated with the provided voltage. In some embodiments, the liquid crystal device may include a three-dimensional (3D) display.

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.

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.

摘要： System and method for video processing. At least one overdrive (OD) look-up table (LUT) is provided, where the at least one OD LUT is dependent on input video levels and at least one parameter indicative of at least one attribute of the system or a user of the system. Video levels for a plurality of pixels for an image are received, as well as the at least one parameter. Overdriven video levels are generated via the at least one OD LUT based on the video levels and the at least one parameter. The overdriven video levels are provided to a display device for display of the image. The reception of video levels and at least one parameter, the generation of overdriven video levels, and the provision of overdriven video levels, may be repeated one or more times in an iterative manner to display a sequence of images.

摘要： Systems and methods for calibrating a three dimensional (3D) stereoscopic display system may include rendering a virtual object on a display of a 3D stereoscopic display system that may include a substantially horizontal display. The virtual object may be geometrically similar to a physical object placed at a location on the display. At least one dimension of the virtual object may be adjusted in response to user input. The adjustment may be such that the at least one dimension of the virtual object is approximately the same as a corresponding at least one dimension of the physical object.
