  • Patent number: 9134556
    Abstract: A voltage may be provided to a liquid crystal addressable element as part of a liquid crystal device. The provided voltage may be reduced from a driven state to a relaxed state in a time period greater than 1 ?s. The reduction may further be performed in less than 20 ms. The liquid crystal device may be a polarization switch, which in some embodiments may be a multi-segment polarization switch. In one embodiment, pulses of limited duration of a light source may be provided to the polarization switch. The manner of voltage reduction may reduce optical bounce of the liquid crystal device and may allow one or more of the pulses of the light source to be shifted later in time.

    Abstract: 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.

  • Patent number: 9106903
    Abstract: In some embodiments, a system for tracking with reference to a three-dimensional display system may include a display device, an image processor, a surface including at least three emitters, at least two sensors, a processor. The display device may image, during use, a first stereo three-dimensional image. The surface may be positionable, during use, with reference to the display device. At least two of the sensors may detect, during use, light received from at least three of the emitters as light blobs. The processor may correlate, during use, the assessed referenced position of the detected light blobs such that a first position/orientation of the surface is assessed. The image processor may generate, during use, the first stereo three-dimensional image using the assessed first position/orientation of the surface with reference to the display.

  • Publication number: 20150160491
    Abstract: 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.

  • Publication number: 20140313295
    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.

  • Publication number: 20140317575
    Abstract: Systems and methods for digitally drawing on virtual 3D object surfaces using a 3D display system. A 3D drawing mode may be enabled and a display screen of the system may correspond to a zero parallax plane of a 3D scene that may present a plurality of surfaces at non-zero parallax planes. User input may be received at a location on the display screen, and in response, a surface may be specified, rendered, and displayed at the zero parallax plane. Further, additional user input on the display screen may be received specifying drawing motion across the rendered and displayed surface. The drawing motion may start at the location and continue across a boundary between the surface and another contiguous surface. Accordingly, in response to the drawing motion crossing the boundary, the contiguous surface may be rendered and displayed at the zero parallax plane along with results of the drawing motion.

  • Publication number: 20130271575
    Abstract: System and method for controlling an imaging microscopy system (IMS). A control module may be coupled to an IMS configured to capture an image of a specified region of a specimen based on a specified perspective by controlling the specimen's position and/or orientation relative to an image capture subsystem of the IMS corresponding to the specified perspective. A 6 DOF tracker may detect position and/or orientation of a 6 DOF object with respect to a display of the IMS corresponding to a perspective for image capture of the specimen, and send indicative information thereof to the control module, which may determine the specified perspective based on the information, and may determine the specified region of the specimen for image capture based on the specified perspective. The control module may send information indicating the specified region and perspective to the IMS, thereby controlling capture of the image by the IMS.
