Abstract: Spatial audio is rendered at a companion device or server connected to a wearable device, where the spatial audio is rendered based on a first pose estimate of the wearable device that is estimated at the companion device or server. The rendered spatial audio is then transmitted to the wearable device. The rendered spatial audio is refined at the wearable device based on a second pose estimate of the wearable device that is estimated at the wearable device. The refined spatial audio is then provided for playback via speakers of the wearable device.

Abstract: A method for depth sensor aided estimation of virtual reality environment boundaries includes generating depth data at a depth sensor of an electronic device based on a local environment proximate the electronic device. A set of initial boundary data is estimated based on the depth data, wherein the set of initial boundary data defines an exterior boundary of a virtual bounded floor plan. The virtual bounded floor plan is generated based at least in part on the set of initial boundary data. Additionally, a relative pose of the electronic device within the virtual bounded floor plan is determined and a collision warning is displayed on a display of the electronic device based on the relative pose.
