Abstract: A depth camera assembly (DCA) includes a direct time of flight system for determining depth information for a local area. The DCA includes an illumination source, a camera, and a controller. The illumination source projects light (e.g., pulse of light) into the local area. The camera detects reflections of the projected light from objects in the local area. Using an internal gating selection procedure, the controller selects a gate window that is likely to be associated with reflection of a pulse of light from an object. The selected gate may be used for depth determination. The internal gating selection procedures may be achieved through external target location and selection or through internal self-selection.

Abstract: Implementations can provide a virtual separate space with respect to a virtual venue hosting a virtual reality (VR) experience, such as a concert, a sports game, a meeting, etc., e.g., to replicate the feeling of a side conversation to discuss the VR experience. Some implementations can create a more intimate experience for users viewing a VR experience by providing a quiet, curated space that can be customized, e.g., by changing the look of users' avatars and their virtual environment, without their interactions being observed by others viewing the VR experience at the virtual venue. The virtual separate space can include a moderated version of the VR experience, such as a smaller version of the VR experience with the sounds of the VR experience muffled. Thus, users within the virtual separate space can step away from the VR experience to enter a more controlled environment, while still enjoying the VR experience.
