Abstract: The disclosed computer-implemented method may include comprising identifying, within a real-world environment, a position of a user relative to a safety boundary. The position of the user is identified by a head-mounted display system comprising a display device. The display device is configured to at least partially obscure visibility of the real-world environment to the user. The method may further include selecting, based on the position of the user, at least a portion of a model of the real-world environment, rendering the portion of the model of the real-world environment, and displaying the rendered portion of the model of the real-world environment via the display device as a notification of the position of the user relative to the safety boundary. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: An apparatus may include a projector that switches from emitting monochromatic light of a first color to emitting monochromatic light of a second color that is different from the first color. The apparatus may also include one or more variable-pitch diffraction gratings that diffract monochromatic light emitted from the projector. The apparatus may further include a controller that changes a pitch of at least one of the one or more variable-pitch diffraction gratings from a first pitch used when the projector is emitting monochromatic light of the first color to a second pitch used when the projector is emitting monochromatic light of the second color.

Abstract: In one embodiment, a computing system may access a first image and a second image of at least a common portion of an environment while a light emission with a predetermined emission pattern is projected by a projector. The first and second images are respectively captured by a first and a second detector that are respectively separated from the projector by a first and a second distance. The system may determine that a first portion of the first image corresponds to a second portion of the second image. The system may compute, using triangulation, a first depth value associated with the first portion and a second depth value associated with the second portion. The system may determine that the first and second depth values match in accordance with one or more predetermined criteria, and generate a depth map of the environment based on at least one of the depth values.

Abstract: A fluidic-device valve having a valve guide with a guide wall surrounding a central axis. The guide wall may include a first guide section, a second guide section, and an interior surface that defines a valve cavity extending longitudinally along the central axis. The valve may also include a valve member disposed within the valve cavity, and the valve member may extend longitudinally along the central axis between a first end and a second end of the valve member. The valve member may be movable within the valve cavity in a first axial direction along the central axis to position a fluid conduit defined by the valve member at a first location by increasing a pressure applied to the second end of the valve member by a pressure source coupled to the second guide section. Various other apparatuses, systems, and methods are also disclosed.

Abstract: In one embodiment, a method includes displaying a horizontal screen visible to a user through a display, determining a horizontal distance between a position of the user and the horizontal screen, determining a vertical distance between a controller associated with the user and the horizontal screen, creating an interaction screen, where the interaction screen and the horizontal screen intersect in a closest point, where the interaction screen is tilted toward the user from the horizontal screen by an angle, detecting a first event that a ray cast from a virtual representation of the controller hits a first point on the interaction screen, translating the first event to a second event that the ray cast hits a second point on the horizontal screen, and displaying a curved line from the controller to the second point on the horizontal screen that is visible to the user through the display.

Abstract: The disclosed special-purpose hardware device may include an image signal processor that receives, from a camera device of a head-mounted-display system, image frames of a physical environment. The special-purpose hardware device may also include a positional tracking component that (1) stores at least a portion of the image frames in a cache of the special-purpose hardware device that has a faster access speed than a main memory of the special-purpose hardware device, (2) tracks, based on the portion of the image frames stored in the cache, a change in the position of the head-mounted display system within the physical environment, and (3) stores the change in the position of the head-mounted-display system in the main memory for use in generating one or more augmented-reality frames. The special-purpose hardware device may further include a frame-output interface that feeds the augmented-reality frames to a display device of the head-mounted-display system.
