摘要: Various concepts for media content streaming are described. Some allow for streaming spatial scene content in a spatially unequal manner so that the visible quality for the user is increased, or the processing complexity or used bandwidth at the streaming retrieval site is decreased. Others allow for streaming spatial scene content in a manner enlarging the applicability to further application scenarios.

摘要: An electronic device is provided that includes at least one image sensor for acquiring a video feed and one or more displays for presenting a passthrough video feed to a user. The electronic device can include a hierarchical failure detection scheme for detecting critical failures on the device. The hierarchical failure detection scheme may include monitoring a condition of a first subsystem with a second subsystem, monitoring a condition of the second subsystem with a third subsystem, monitoring a condition of the third subsystem with a fourth subsystem, and so on. The displays can operate in a first video passthrough mode or a second video passthrough mode based on the condition of the first subsystem as monitored by the second subsystem, the condition of the second subsystem as monitored by the third subsystem, and/or the condition of the third subsystem as monitored by the fourth subsystem.

摘要: Examples are disclosed that relate to providing image data to a user in a defined space of a surrounding environment from a perspective of the user. One example provides a computing system, comprising a logic subsystem, and a storage subsystem comprising instructions executable by the logic subsystem to obtain information regarding a pose of a user within a defined space, based upon the pose of the user, determine a portion of an environment surrounding the defined space toward which the user is looking, obtain image data representing the portion of the environment from a perspective of the user, and provide the image data for display via a display device within the defined space.

摘要: An autostereoscopic display system includes a transmissive display panel including a backlight having an array of backlight pixels, a selectively-selectively-transmissive display pixel matrix having a first side facing the backlight and an opposing second side, the selectively-transmissive display pixel matrix comprising an array of display pixels, a first lenticular array disposed between the backlight and the first side of the selectively-transmissive display pixel matrix, and a second lenticular array disposed facing the second side of the selectively-transmissive display pixel matrix. The backlight is configured to separately activate different subsets of the backlight pixels such that light emitted from an activated subset of backlight pixels and transmitted through the first lenticular array, the selectively-transmissive display pixel matrix, and the second lenticular array is emitted by the display panel as display light in a corresponding separate direction relative to the display panel.
