摘要: Systems and methods for implementing methods for cloud-based rendering of interactive augmented reality (AR) and/or virtual reality (VR) experiences. A client device may initiate execution of a content application on a server and provide information associated with the content application to the server. The client device may initialize, while awaiting a notification from the server, local systems associated with the content application and, upon receipt of the notification, provide, to the server, information associated with the local systems. Further, the client device may receive, from the server, data associated with the content application and render an AR/VR scene based on the received data. The data may be based, at least in part, on the information associated with the local system. The providing and receiving may be performed periodically, e.g., at a rate to sustain a comfortable viewing environment of the AR/VR scene by a user of the client device.

摘要: Systems and methods for providing an electrical waveform to a pi-cell polarization switch. The electrical waveform may reduce/limit ion accumulation in and/or light leakage associated with the polarization switch. The electrical waveform may include multiple segments, e.g., a first segment may drive the polarization switch to a first polarization state and may be defined by a first portion having a first voltage level and a first polarity and a second portion having the first voltage level and a second polarity opposite the first polarity and a second segment, occurring after the first segment, that may drive the polarization switch to the second polarization state. The second segment may be defined by a second voltage level having the first polarity. An absolute value of the first voltage level may be greater than an absolute value of the second voltage level.

摘要: 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.

摘要: Systems and methods for calibrating a three dimensional (3D) stereoscopic display system may include rendering a virtual model on a display of a 3D stereoscopic display system that may include a substantially horizontal display. The virtual model may be geometrically similar to a physical object placed at a location on the display. A vertex of the virtual model may be adjusted in response to user input. The adjustment may be such that the vertex of the virtual model is substantially coincident with a corresponding vertex of the physical object.

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: 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.
