  • System and method for interactive 360 video playback based on user location
    Patent number: 11137825
    Abstract: A Head-Mounted Display, HMD, apparatus for recording a video and playing back the video to a viewer in a Virtual Reality, VR, environment. A geographical area is recorded with an omnidirectional video recording camera by dividing the geographical area into a plurality of area portions and recording in separate video sections, each of the area portions while moving the camera in different directions. Time points in each video section are associated with virtual locations of the viewer. At a time point providing the viewer with a choice of directions to proceed, the system receives the viewer's choice and presents to the viewer, a video section corresponding to the virtual location of the viewer and desired direction of movement. The viewer's choice may be indicated by detecting a direction of the viewer's field of view or by receiving from the viewer, a response to a banner notification.
