Abstract: In a system having a user-portable display device, a method includes maintaining a lightfield data structure representing at least a portion of a four-dimensional (4D) lightfield for a three-dimensional (3D) world in association with a first pose of the user-portable display device relative to the 3D world. The method further includes determining a second pose of the user-portable display device relative to the 3D world, the second pose comprising an updated pose of the user-portable display device. The method additionally includes generating a display frame from the lightfield data structure based on the second pose, the display frame representing a field of view of the 3D world from the second pose.

Abstract: In a system for teleporting and scaling in a virtual reality environment, a user may teleport from a first virtual location, being experienced at a first scale, to a second virtual location, to be experienced at a second scale. The user may select the new, second virtual location and the new, second scale with a single external input via a handheld electronic device so that, upon release of a triggering action of the electronic device, the user may teleport to the newly selected second virtual location at the newly selected scale.

Abstract: A technique may include determining a cumulative movement of an input controller in a physical environment, determining a scaling factor based on the cumulative movement of the input controller in the physical environment, determining a current movement of the input controller in the physical environment for a time period, and registering, in a virtual environment, only a portion of the current movement of the input controller based on the scaling factor.
