Abstract: A video pass-through computing system includes a head-mounted display device including a display, a camera configured to image a physical scene according to an exposure timing, and an augmented reality control circuit configured to receive a virtual image pixel stream and composite the camera image pixel stream with the virtual image pixel stream to generate a display image pixel stream output to the display, and if a corresponding pixel of the camera image pixel stream is not in temporal synchronization with a pixel of the virtual image pixel stream adjust the exposure timing of the camera.

Abstract: An augmented reality display device includes a near-eye display configured to present imagery to a user eye. A camera is configured to capture light from a real-world environment and produce output useable to contribute to the imagery presented to the user eye via the near-eye display. The camera includes an aperture configured to receive the light from the real-world environment and an image sensor configured to respond to the light received from the real-world environment by generating sensor output signals useable to produce images on the near-eye display depicting the real-world environment. One or more optical elements provide an optical path for light from the aperture to the image sensor, the optical path having a length that is within a threshold of a distance between the user eye and the aperture of the camera.

Abstract: Edits on a content item, such as a document, are divided into microtasks. The microtasks associated with a document can be automatically identified based on a workflow or can be identified by a user associated with the content item or an administrator. At a later time, the user can complete the microtasks for a content item using an application associated with their smart phone or tablet. The application may present the microtasks in a game-like environment where the user can compete with other users based on metrics such as number of microtasks completed in a day or fastest completion time. In addition, the user can earn rewards such as badges, coupons, or credits by completing microtasks. In this way, users can use time that would have been wasted playing games to complete their content items, while still experiencing some of the fun and competition associated with the games.

Abstract: A first image is provided to a projector, which is configured to project the first image on a projection screen. A captured first image is received from a camera configured to capture the projected first image and an occluding object between the projector and the projection screen. A key including a difference between the captured first image and the first image is generated. A second image is modified according to the key to generate a new second image. The new second image is provided to the projector, which is further configured to project the new second image.

Abstract: Technologies are described herein for providing sterilization of a touchscreen or other tactile input surface of a user input device. A self-sterilizing user input device includes a touchscreen for receiving tactile user input and an ultraviolet (UV) light source that emits UV light onto a touchscreen at a sterilization wavelength. A controller selectively activates and deactivates the UV light source according to whether a user is at or near the user input device. According to one aspect, the user input device includes a backlight to illuminate the touchscreen. The UV light source is positioned with the backlight to provide the UV light from a rear side of the touchscreen.

Abstract: A method of providing a seamless data communication experience across a presence aware device and an additional presence aware device is disclosed. A data communication experience may be transferred from a presence aware device to an additional presence aware device when a user selects to switch to an additional presence aware device or leaves the presence of the presence aware device.
