Abstract: In one general aspect, a method can include triggering display of a virtual environment in a head mounted display (HMD) device operating in a physical environment, triggering display of a first virtual object representing a second virtual object, the first virtual object having a size smaller than a size of the second virtual object, receiving an indication of an interaction of a user with the first virtual object, the user having a first size larger than the size of the first virtual object, and triggering an interaction with the second virtual object in response to an interaction with the first virtual object, the user having a second size larger than the first size when interacting with the second virtual object.

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: 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.
