Abstract: The disclosure provides methods and systems for warning a user of a head mounted display that the user approaches an edge of field of view of a camera or one or more tangible obstacles. The warning includes presenting audio and/or displayable messages to the user, or moving the display(s) of the head mounted displays away of the user's eyes. The determination that the user approaches the edge of scene or a tangible obstacle is made by dynamically tracking motions of the users through analysis of images and/or depth data obtained from image sensor(s) and/or depth sensor(s) secured to either the head mounted display, arranged outside of the scene and not secured to the head mounted display, or a combination of both.

Abstract: Methods and systems for presenting an object on to a screen of a head mounted display (HMD) include receiving an image of a real-world environment in proximity of a user wearing the HMD. The image is received from one or more forward facing cameras of the HMD and processed for rendering on a screen of the HMD by a processor within the HMD. A gaze direction of the user wearing the HMD, is detected using one or more gaze detecting cameras of the HMD that are directed toward one or each eye of the user. Images captured by the forward facing cameras are analyzed to identify an object captured in the real-world environment that is in line with the gaze direction of the user, wherein the image of the object is rendered at a first virtual distance that causes the object to appear out-of-focus when presented to the user. A signal is generated to adjust a zoom factor for lens of the one or more forward facing cameras so as to cause the object to be brought into focus.

The computing system processes image data captured of the HMD when worn by a user. The image data includes at least one of the set of LEDs of the front unit and at least one of the set of LEDs of the rear section to identify the separation distance for a current adjustment of the connector.

Abstract: Gaze tracking data may representing a user's gaze with respect to one or more images transmitted to a user are analyzed to determine one or more regions of interest. Compression of the one or more transmitted images is adjusted so that fewer bits are needed to transmit data for portions of an image outside the one or more regions interest than for portions of the image within the one or more regions of interest.

Abstract: Gaze tracking data representing a viewer's gaze with respect to one or more images presented to the viewer is used to generate foveated image data representing one or more foveated images characterized by a higher level of detail within one or more regions of interest and a lower level of detail outside the regions of interest. The image data for portions outside the one or more regions of interest is selectively filtered to reduce visual artifacts due to contrast resulting from the lower level of detail before compositing foveated images for presentation.

Abstract: Foveated rendering based on user gaze tracking may be adjusted to account for the realities of human vision. Gaze tracking error and state parameters may be determined from gaze tracking data representing a user's gaze with respect to one or more images presented to a user. Adjusted foveation data representing an adjusted size and/or shape of one or more regions of interest in one or more images to be subsequently presented to a user may be generated based on the one or more gaze tracking error or state parameters. Foveated image data representing one or more foveated images may be generated with the adjusted foveation data. The foveated images are characterized by level of detail within the one or more regions of interest and lower level of detail outside the one or more regions of interest. The foveated images may then be presented to the user.
