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.

Abstract: An HMD adjusts adjusting depth information based on detected motion of the system. The HMD includes a depth camera that collects depth data for objects in the local environment of the HMD. The HMD further includes an inertial measurement unit (IMU) including non-visual motion sensors such as one or more accelerometers, gyroscopes, and the like. The HMD adjusts the received depth information based on motion data provided by the IMU, thereby improving the accuracy of the depth information, and in turn reducing visual artifacts that can result from inaccuracies in the depth information.

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