Abstract: A gaze tracking system comprising a first camera operable to capture images of a user within an environment, a second camera, having a smaller field of view than the first camera, operable to capture images of at least one of the user's eyes, an eye identification unit operable to identify a location of at least one of the user's eyes from images captured by the first camera, a camera control unit operable to modify the position and/or orientation of the second camera in dependence upon the detected location of the at least one of the user's eyes, so as to cause the second camera to be able to capture images of at least one of the user's eyes, and a gaze direction identification unit operable to identify a gaze direction of the user from images captured by the second camera.

Abstract: A method includes: rendering a field of view of a virtual environment for a first user of a head mounted display, rendering a view of the virtual environment outside the field of view of the first user at a lower resolution, outputting the rendered field of view for display to the first user, and recording the combined render as a video for subsequent viewing by a second user. A corresponding method includes requesting to download or stream the video from a remote source, receiving the download or stream of the video from the remote source, and outputting at least part of the stream or video for display to a second user wearing a head mounted display.

Abstract: A method of video recording comprises the steps of: rendering a field of view of a virtual environment for a first user of a head mounted display at a first resolution, rendering a view of the virtual environment outside the field of view of the first user at a second lower resolution than the first resolution, outputting the rendered field of view for display to the first user, and recording the combined render as a video for subsequent viewing by a second user; meanwhile a corresponding method of video playback comprises requesting to download or stream the video from a remote source, receiving the download or stream of the video from the remote source, and outputting at least part of the stream or video for display to a second user wearing a head mounted display, wherein the step of outputting the stream of video comprises detecting the field of view of the second user wearing the head mounted display, and providing the corresponding portion of the recorded stream or video for output to the head mounted display of the second user.
