摘要： 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

摘要： Systems and methods for capturing a two dimensional (2D) image of a portion of a three dimensional (3D) scene may include a computer rendering a 3D scene on a display from a user's point of view (POV). A camera mode may be activated in response to user input and a POV of a camera may be determined. The POV of the camera may be specified by position and orientation of a user input device coupled to the computer, and may be independent of the user's POV. A 2D frame of the 3D scene based on the POV of the camera may be determined and the 2D image based on the 2D frame may be captured in response to user input. The 2D image may be stored locally or on a server of a network.

摘要： 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 μs. 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.

摘要： Systems and methods for implementing methods for user selection of a virtual object in a virtual scene. A user input may be received via a user input device. The user input may be an attempt to select a virtual object from a plurality of virtual objects rendered in a virtual scene on a display of a display system. A position and orientation of the user input device may be determined in response to the first user input. A probability the user input may select each virtual object may be calculated via a probability model. Based on the position and orientation of the user input device, a ray-cast procedure and a sphere-cast procedure may be performed to determine the virtual object being selected. The probability of selection may also be considered in determining the virtual object. A virtual beam may be rendered from the user input device to the virtual object.

摘要： Systems and methods for enhancing trackability of a passive stylus. A six degree of freedom (6DoF) location and orientation of a passive stylus may be tracked by a tracking system via a retroreflector system disposed on the passive stylus. Additionally, characteristic movements of one of a user's finger, hand, and/or wrist may be recognized by the tracking system. The passive stylus may useable to interact with a virtual 3D scene being displayed via a 3D display. A user input via the passive stylus may be determined based on the tracked 6DoF location and orientation of the passive stylus and/or the recognized characteristic movements. The retroreflector system may include multiple patterns of retroreflectors and one of the patterns may be a spiral pattern of retroreflectors disposed along a longitudinal axis of the passive stylus.
