  • Publication number: 20150370111
    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.

  • Publication number: 20150350635
    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.

  • Patent number: 9201568
    Abstract: Tracking objects presented within a stereo three-dimensional (3D) scene. The user control device may include one or more visually indicated points for at least one tracking sensor to track. The user control device may also include other position determining devices, for example, an accelerometer and/or gyroscope. Precise 3D coordinates of the stylus may be determined based on location information from the tracking sensor(s) and additional information from the other position determining devices. A stereo 3D scene may be updated to reflect the determined coordinates.

  • Patent number: 9189188
    Abstract: Communication systems and methods for enhancing communications between users featuring a central service which formats messages into a printer-friendly format. The format of the delivered message is based on preference settings established by the recipient or an authorized agent of the recipient. The messages are delivered to a device, such as a printer. Messages can be sent to the service in any format and can include text, photographs, URLs, and/or a variety of file types. The messages are then parsed by the service and formatted for delivery to the device.

  • Patent number: 9123171
    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.
