Abstract: Examples are disclosed herein that relate to receiving virtual reality input. An example provides a head-mounted display device comprising a sensor system, a display, a logic machine, and a storage machine holding instructions executable by the logic machine. The instructions are executable to execute a 3D virtual reality experience on the head-mounted display device, track, via the sensor system, a touch-sensitive input device, render, on the display, in a 3D location in the 3D virtual reality experience based on the tracking of the touch-sensitive input device, a user interface, receive, via a touch sensor of the touch-sensitive input device, a user input, and, in response to receiving the user input, control the 3D virtual reality experience to thereby vary visual content being rendered on the display.

Abstract: An HMD device is configured to vertically adjust the ground plane of a rendered virtual reality environment that has varying elevations to match the flat real world floor so that the device user can move around to navigate and explore the environment and always be properly located on the virtual ground and not be above it or underneath it. Rather than continuously adjust the virtual reality ground plane, which can introduce cognitive dissonance discomfort to the user, when the user is not engaged in some form of locomotion (e.g., walking), the HMD device establishes a threshold radius around the user within which virtual ground plane adjustment is not performed. The user can make movements within the threshold radius without the HMD device shifting the virtual terrain. When the user moves past the threshold radius, the device will perform an adjustment as needed to match the ground plane of the virtual reality environment to the real world floor.

Abstract: An electronic device displays a field of view of a camera with a view of a three-dimensional space and updates the field of view based on changes detected by the camera. While a measurement-point-creation indicator is over a determined anchor point in the field of view, the device changes a visual appearance of the indicator to indicate that a measurement point will be added at the anchor point if a touch input meets first criteria. In response to a touch input that meets the first criteria, a measurement point is added at the anchor point if the indicator is over the anchor point, and at a location away from the anchor point if not. In response to movement of the camera changing the field of view, if the field of view does not include a feature to which measurement points can be added, the measurement-point-creation indicator ceases to be displayed.

Abstract: Systems and methods for localization for mobile devices are described. Some implementations may include accessing motion data captured using one or more motion sensors; determining, based on the motion data, a coarse localization, wherein the coarse localization includes a first estimate of position; obtaining one or more feature point maps, wherein the feature point maps are associated with a position of the coarse localization; accessing images captured using one or more image sensors; determining, based on the images, a fine localization pose by localizing into a feature point map of the one or more feature point maps, wherein the fine localization pose includes a second estimate of position and an estimate of orientation; generating, based on the fine localization pose, a virtual object image including a view of a virtual object; and displaying the virtual object image.

Abstract: A method includes obtaining first pass-through image data characterized by a first pose. The method includes obtaining respective pixel characterization vectors for pixels in the first pass-through image data. The method includes identifying a feature of an object within the first pass-through image data in accordance with a determination that pixel characterization vectors for the feature satisfy a feature confidence threshold. The method includes displaying the first pass-through image data and an AR display marker that corresponds to the feature. The method includes obtaining second pass-through image data characterized by a second pose. The method includes transforming the AR display marker to a position associated with the second pose in order to track the feature. The method includes displaying the second pass-through image data and maintaining display of the AR display marker that corresponds to the feature of the object based on the transformation.

Abstract: An HMD device with a see-through display and depth sensing capability is configured to selectively dim or fade out a display of a virtual reality environment to enable a user to see the real world without obstruction by the virtual world when a distance between the user and a real world object is determined to be less than a threshold distance. The current height of the user's head (i.e., the distance from head to ground) may be utilized when performing the dimming/fading so that different threshold distances can be used depending on whether the user is standing or seated.

Abstract: Tracking a user head position detects a change to a new head position and, in response, a remote camera is instructed to move to a next camera position. A camera image frame, having an indication of camera position, is received from the camera. Upon the camera position not aligning with the next camera position, an assembled image frame is formed, using image data from past views, and rendered to appear to the user as if the camera moved in 1:1 alignment with the user's head to the next camera position.

Abstract: An application running on a computing platform that employs three-dimensional (3D) modeling is extended using a virtual viewport into which 3D holograms are rendered by a mixed-reality head mounted display (HMD) device. The HMD device user can position the viewport to be rendered next to a real world 2D monitor and use it as a natural extension of the 3D modeling application. For example, the user can interact with modeled objects in mixed-reality and move objects between the monitor and the viewport. The 3D modeling application and HMD device are configured to exchange scene data for modeled objects (such as geometry, lighting, rotation, scale) and user interface parameters (such as mouse and keyboard inputs). The HMD device implements head tracking to determine where the user is looking so that user inputs are appropriately directed to the monitor or viewport.
