Abstract: A see-through head-mounted display (HMD) device, e.g., in the form of glasses, provides view an augmented reality image including text, such as in an electronic book or magazine, word processing document, email, karaoke, teleprompter or other public speaking assistance application. The presentation of text and/or graphics can be adjusted based on sensor inputs indicating a gaze direction, focal distance and/or biological metric of the user. A current state of the text can be bookmarked when the user looks away from the image and subsequently resumed from the bookmarked state. A forward facing camera can adjust the text if a real word object passes in front of it, or adjust the appearance of the text based on a color of pattern of a real world background object. In a public speaking or karaoke application, information can be displayed regarding a level of interest of the audience and names of audience members.

Abstract: Techniques are provided for displaying electronic communications using a head mounted display (HMD). Each electronic communication may be displayed to represent a physical object that indentifies it as a specific type or nature of electronic communication. Therefore, the user is able to process the electronic communications more efficiently. In some aspects, computer vision allows a user to interact with the representation of the physical objects. One embodiment includes accessing electronic communications, and determining physical objects that are representative of at least a subset of the electronic communications. A head mounted display (HMD) is instructed how to display a representation of the physical objects in this embodiment.

Abstract: Techniques are provided for viewing windows for video streams. A video stream from a video capture device is accessed. Data that describes movement or position of a person is accessed. A viewing window is placed in the video stream based on the data that describes movement or position of the person. The viewing window is provided to a display device in accordance with the placement of the viewing window in the video stream. Motion sensors can detect motion of the person carrying the video capture device in order to dampen the motion such that the video on the remote display does not suffer from motion artifacts. Sensors can also track the eye gaze of either the person carrying the mobile video capture device or the remote display device to enable control of the spatial region of the video stream shown at the display device.
