Abstract: A system for identifying an AR tag and determining a location for a virtual object within an augmented reality environment corresponding with the AR tag is described. In some environments, the location of a virtual object corresponding with a particular AR tag may be determined by identifying a predefined object, determining an orientation and a scale of the predefined object relative to a head-mounted display device (HMD) based on a model of the predefined object, and inferring the location of the virtual object based on the orientation and the scale of the predefined object. In some cases, an identification of the particular AR tag corresponding with the virtual object may be acquired by aggregating and analyzing individual identity determinations from a plurality of HMDs within an augmented reality environment.

Abstract: Techniques are provided for rendering, in a see-through, near-eye mixed reality display, a virtual object within a virtual hole, window or cutout. The virtual hole, window or cutout may appear to be within some real world physical object such as a book, table, etc. The virtual object may appear to be just below the surface of the physical object. In a sense, the virtual world could be considered to be a virtual container that provides developers with additional locations for presenting virtual objects. For example, rather than rendering a virtual object, such as a lamp, in a mixed reality display such that appears to sit on top of a real world desk, the virtual object is rendered such that it appears to be located below the surface of the desk.

Abstract: Technology is disclosed herein to help a user navigate through large amounts of content while wearing a see-through, near-eye, mixed reality display device such as a head mounted display (HMD). The user can use a physical object such as a book to navigate through content being presented in the HMD. In one embodiment, a book has markers on the pages that allow the system to organize the content. The book could have real content, but it could be blank other than the markers. As the user flips through the book, the system recognizes the markers and presents content associated with the respective marker in the HMD.

Abstract: Techniques are provided for allowing a user to select a region within virtual imagery, such as a hologram, being presented in an HMD. The user could select the region by using their hands to form a closed loop such that from the perspective of the user, the closed loop corresponds to the region the user wishes to select. The user could select the region by using a prop, such as a picture frame. In response to the selection, the selected region could be presented using a different rendering technique than other regions of the virtual imagery. Various rendering techniques such as zooming, filtering, etc. could be applied to the selected region. The identification of the region by the user could also serve as a selection of an element in that portion of the virtual image.

Abstract: A system for generating and displaying holographic visual aids associated with a story to an end user of a head-mounted display device while the end user is reading the story or perceiving the story being read aloud is described. The story may be embodied within a reading object (e.g., a book) in which words of the story may be displayed to the end user. The holographic visual aids may include a predefined character animation that is synchronized to a portion of the story corresponding with the character being animated. A reading pace of a portion of the story may be used to control the playback speed of the predefined character animation in real-time such that the character is perceived to be lip-syncing the story being read aloud. In some cases, an existing book without predetermined AR tags may be augmented with holographic visual aids.

Abstract: Technology is described for providing a virtual spectator experience for a user of a personal A/V apparatus including a near-eye, augmented reality (AR) display. A position volume of an event object participating in an event in a first 3D coordinate system for a first location is received and mapped to a second position volume in a second 3D coordinate system at a second location remote from where the event is occurring. A display field of view of the near-eye AR display at the second location is determined, and real-time 3D virtual data representing the one or more event objects which are positioned within the display field of view are displayed in the near-eye AR display. A user may select a viewing position from which to view the event. Additionally, virtual data of a second user may be displayed at a position relative to a first user.
