A method performed by an electronic device for requesting tiles relating to a viewport of an ongoing omnidirectional video stream is provided. The ongoing omnidirectional video stream is provided by a server to be displayed to a user of the electronic device. The electronic device predicts for an impending time period, a future head gaze of the user in relation to a current head gaze of the user, based on: A current head gaze relative to a position of shoulders of the user, a limitation of the head gaze of the user bounded by the shoulders position of the user, and a current eye gaze and eye movements of the user. The electronic device then sends a request to the server. The request requests tiles relating to the viewport for the impending time period, selected based on the predicted future head gaze of the user.

Provided is a method for realizing 3D image display, comprising: detecting a posture change of a 3D display device, wherein the 3D display device comprises a multi-viewpoint 3D display screen, the multi-viewpoint 3D display screen comprises a plurality of composite pixels and a plurality of spherical gratings covering the plurality of composite pixels, each composite pixel of the plurality of composite pixels comprises a plurality of composite subpixels, and each composite subpixel of the plurality of composite subpixels comprises a plurality of subpixels corresponding to a plurality of viewpoints; and when detecting the posture change of the 3D display device, adjusting a display orientation of a displayed 3D image so that the 3D image is kept in an initial display orientation before the posture change of the 3D display device. A 3D display device, a computer-readable storage medium, and a computer program product are further provided.

An object of the present invention is to obtain calibration data more easily in a VR (Virtual Reality) device. a user wearing a pair of VR goggles visually recognizes overlapped marker images displayed in the 360-degree VR space, and a stationary state is detected when the images for right and left eyes are overlapped, and when the stationary state satisfies a predetermined condition set in advance, one of the plurality of marker images displayed on the display in this state, which is at the center, is set as a marker image for calibration setting, calibration data of the interpupillary distance based on the marker image for calibration setting having been set is acquired, and the acquired calibration data is set as calibration data used for subsequent reproduction of images.

Systems and methods for using peripheral vision in virtual, augmented, and mixed reality (collectively referred to as “xR”) applications are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: render an object in a peripheral field-of-view of a user; detect at least one of: the user's eye movement, or the user's head rotation; and determine whether to re-render the object based upon the detection.
