Abstract: A method, computer readable medium, and system are disclosed for redirecting a user's movement through a physical space while the user views a virtual environment. A temporary visual suppression event is detected when a user's eyes move relative to the user's head while viewing a virtual scene displayed on a display device, an orientation of the virtual scene relative to the user is modified to direct the user to physically move along a planned path through a virtual environment corresponding to the virtual scene, and the virtual scene is displayed on the display device according to the modified orientation.

Abstract: A method, computer readable medium, and system are disclosed for computing a path for a user to move along within a physical space while viewing a virtual environment in a virtual reality system. A path for a user to physically move along through a virtual environment is determined based on waypoints and at least one characteristic of the physical environment within which the user is positioned, position data for the user is received indicating whether and how much a current path taken by the user has deviated from the path, and an updated path is computed through the virtual environment based on the waypoints and the at least one characteristic of the physical environment.

Abstract: A method, computer readable medium, and system are disclosed for adjusting an angular sampling rate during rendering. The method includes the steps of determining a location of a gaze within a displayed scene, and adjusting, during a rendering of the scene, an angular sampling rate used to render at least a portion of the scene, based on the location of the gaze within the displayed scene.
