Abstract: A method of interacting with an artificial-reality (AR) content at an AR headset that includes cameras and displays is described. The method includes, while the AR headset has a first position within a physical environment that includes an object, if a distance of the object is within a threshold collision distance from the AR headset, presenting a meshed representation of the object. The meshed representation is displayed at first respective locations on the displays such that the meshed representation is viewable within the artificial reality. After the AR headset moves to a second position with a different distance, and if the different distance is within the threshold collision distance from the AR headset, moving the meshed representation of the object to second respective locations within the artificial reality. The second respective locations correspond to the position of the object in the physical environment.

Abstract: A system generates a plurality of spatial points based on depth measurements of physical objects. The system determines, based on the plurality of spatial points, an occupancy score for each voxel within a plurality of voxels. The system identifies, based on a gaze of the user, a first set of occupied voxels that are in a field of view of the user and a second set of occupied voxels that are outside the field of view of the user. The system updates the occupancy scores of the first set of occupied voxels by temporally decaying one or more of the plurality of spatial points within the first set of occupied voxels. The system maintains the occupancy scores of the second set of occupied voxels. The system detects intrusions in a predefined subspace within a physical space based on the updated occupancy scores of the first set of occupied voxels.

Abstract: A mixed reality (MR) simulation system includes a console and a head mounted device (HMD). The MR system captures stereoscopic images from a real-world environment using outward-facing stereoscopic cameras mounted to the HMD. The MR system preprocesses the stereoscopic images to maximize contrast and then extracts a set of features from those images, including edges or corners, among others. For each feature, the MR system generates one or more two-dimensional (2D) polylines. Then, the MR system triangulates between 2D polylines found in right side images and corresponding 2D polylines found in left side images to generate a set of 3D polylines. The MR system interpolates between 3D vertices included in the 3D polylines or extrapolates additional 3D vertices, thereby generating a geometric reconstruction of the real-world environment. The MR system may map textures derived from the real-world environment onto the geometric representation faster than the geometric reconstruction is updated.
