In particular embodiments, a computing system may divide at least a portion of a physical space surrounding a user into a plurality of three-dimensional (3D) regions, wherein each of the 3D regions is associated with an area of a plurality of areas in a plane. The system may generate estimated locations of features of objects in the portion of the physical space. Based on the estimated locations, the system may determine an occupancy state of each of the plurality of 3D regions. Then based on the occupancy states of the plurality of 3D regions, the system may determine that one or more of the plurality of areas have respective airspaces that are likely unoccupied by objects.

Systems, methods, and media for detecting object-free space

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.

Systems and methods for detecting objects within the boundary of a defined space while in artificial reality

In one embodiment for generating passthrough, a computing system may access images of an environment captured by cameras of a device worn by a user. The system may generate, based on the images, depth measurements of objects in the environment. The system may generate a mesh covering a field of view of the user and then update the mesh based on the depth measurements to represent a contour of the objects in the environment. The system may determine a first viewpoint of a first eye of the user and render a first output image based on the first viewpoint and the updated mesh. The system may then display the first output image on a first display of the device, the first display being configured to be viewed by the first eye of the user.

Systems, methods, and media for generating visualization of physical environment in artificial reality

In one embodiment, a method includes generating a plurality of spatial points based on depth measurements of physical objects within a physical space surrounding a user and determining, based on the spatial points, a location at which a physical object is likely to exist. The method then renders, based on the location of the physical object, a virtual space representing the physical space. This virtual space may include a virtual object representing the physical object. The method displays the virtual space to the user, and, while displaying the virtual space, receives input from the user indicating a boundary of a subspace within the virtual space, and detects that at least a portion of the virtual object is within the subspace. Finally, the method updates the virtual space to indicate that the portion of the virtual object is within the subspace.
