The see-through display is configured to visually augment an appearance of a physical space to a user viewing the physical space through the see-through display. The virtual reality engine is configured to cause the see-through display to visually present a virtual monitor that appears to be integrated with the physical space to a user viewing the physical space through the see-through display.

Abstract: A virtual skeleton includes a plurality of joints and provides a machine readable representation of a human target observed with a three-dimensional depth camera. A relative position of a hand joint of the virtual skeleton is translated as a gestured control, and a three-dimensional virtual world is controlled responsive to the gestured control.

Abstract: A system for generating a virtual gaming environment based on features identified within a real-world environment, and adapting the virtual gaming environment over time as the features identified within the real-world environment change is described. Utilizing the technology described, a person wearing a head-mounted display device (HMD) may walk around a real-world environment and play a virtual game that is adapted to that real-world environment. For example, the HMD may identify environmental features within a real-world environment such as five grassy areas and two cars, and then spawn virtual monsters based on the location and type of the environmental features identified. The location and type of the environmental features identified may vary depending on the particular real-world environment in which the HMD exists and therefore each virtual game may look different depending on the particular real-world environment.

Abstract: A capture device may capture a user's motion and a display device may display a model that maps to the user's motion, including gestures that are applicable for control. A user may be unfamiliar with a system that maps the user's motions or not know what gestures are applicable for an executing application. A user may not understand or know how to perform gestures that are applicable for the executing application. Providing visual feedback representing instructional gesture data to the user can teach the user how to properly gesture. The visual feedback may be provided in any number of suitable ways. For example, visual feedback may be provided via ghosted images, player avatars, or skeletal representations. The system can process prerecorded or live content for displaying visual feedback representing instructional gesture data. The feedback can portray the deltas between the user's actual position and the ideal gesture position.

Abstract: A see-through head-mounted display (HMD) device provides an augmented reality image which is associated with a real-world object, such as a picture frame, wall or billboard. Initially, the object is identified by a user, e.g., based on the user gazing at the object for a period of time, making a gesture such as pointing at the object and/or providing a verbal command. The location and visual characteristics of the object are determined by a front-facing camera of the HMD device, and stored in a record. The user selects from among candidate data streams, such as a web page, game feed, video or stocker ticker. Subsequently, when the user is in the location of the object and looks at the object, the HMD device matches the visual characteristics to the record to identify the data stream, and displays corresponding augmented reality images registered to the object.

Abstract: The technology causes disappearance of a real object in a field of view of a see-through, mixed reality display device system based on user disappearance criteria. Image data is tracked to the real object in the field of view of the see-through display for implementing an alteration technique on the real object causing its disappearance from the display. A real object may satisfy user disappearance criteria by being associated with subject matter that the user does not wish to see or by not satisfying relevance criteria for a current subject matter of interest to the user. In some embodiments, based on a 3D model of a location of the display device system, an alteration technique may be selected for a real object based on a visibility level associated with the position within the location. Image data for alteration may be prefetched based on a location of the display device system.

Abstract: The technology provides contextual personal information by a mixed reality display device system being worn by a user. A user inputs person selection criteria, and the display system sends a request for data identifying at least one person in a location of the user who satisfy the person selection criteria to a cloud based application with access to user profile data for multiple users. Upon receiving data identifying the at least one person, the display system outputs data identifying the person if he or she is within the field of view. An identifier and a position indicator of the person in the location is output if not. Directional sensors on the display device may also be used for determining a position of the person. Cloud based executing software can identify and track the positions of people based on image and non-image data from display devices in the location.

Abstract: Embodiments are disclosed that relate to interacting with a user interface via feedback provided by an avatar. One embodiment provides a method comprising receiving depth data, locating a person in the depth data, and mapping a physical space in front of the person to a screen space of a display device. The method further comprises forming an image of an avatar representing the person, outputting to a display an image of a user interface comprising an interactive user interface control, and outputting to the display device the image of the avatar such that the avatar faces the user interface control. The method further comprises detecting a motion of the person via the depth data, forming an animated representation of the avatar interacting with the user interface control based upon the motion of the person, and outputting the animated representation of the avatar interacting with the control.

Abstract: Technology is described for automatically determining placement of one or more interaction zones in an augmented reality environment in which one or more virtual features are added to a real environment. An interaction zone includes at least one virtual feature and is associated with a space within the augmented reality environment with boundaries of the space determined based on the one or more real environment features. A plurality of activation criteria may be available for an interaction zone and at least one may be selected based on at least one real environment feature. The technology also describes controlling activation of an interaction zone within the augmented reality environment. In some examples, at least some behavior of a virtual object is controlled by emergent behavior criteria which defines an action independently from a type of object in the real world environment.

Abstract: Embodiments for interacting with an executable virtual object associated with a real object are disclosed. In one example, a method for interacting with an executable virtual object associated with a real object includes receiving sensor input from one or more sensors attached to the portable see-through display device, and obtaining information regarding a location of the user based on the sensor input. The method also includes, if the location includes a real object comprising an associated executable virtual object, then determining an intent of the user to interact with the executable virtual object, and if the intent to interact is determined, then interacting with the executable object.

Abstract: A system for generating an augmented reality environment in association with one or more attractions or exhibits is described. In some cases, a see-through head-mounted display device (HMD) may acquire one or more virtual objects from a supplemental information provider associated with a particular attraction. The one or more virtual objects may be based on whether an end user of the HMD is waiting in line for the particular attraction or is on (or in) the particular attraction. The supplemental information provider may vary the one or more virtual objects based on the end user's previous experiences with the particular attraction. The HMD may adapt the one or more virtual objects based on physiological feedback from the end user (e.g., if a child is scared). The supplemental information provider may also provide and automatically update a task list associated with the particular attraction.

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.

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.

Abstract: Techniques for facilitating interaction with an application in a motion capture system allow a person to easily begin interacting without manual setup. A depth camera system tracks a person in physical space and determines a probabilistic measure of the person's intent to engage of disengage with the application based on location, stance and movement. Absolute location in a field of view of the depth camera, and location relative to another person, can be evaluated. Stance can include facing a depth camera, indicating a willingness to interact. Movements can include moving toward or away from a central area in the physical space, walking through the field of view, and movements which occur while standing generally in one location, such as moving one's arms around, gesturing, or shifting weight from one foot to another.

Abstract: A right near-eye display displays a right-eye virtual object, and a left near-eye display displays a left-eye virtual object. A first texture derived from a first image of a scene as viewed from a first perspective is overlaid on the right-eye virtual object and a second texture derived from a second image of the scene as viewed from a second perspective is overlaid on the left-eye virtual object. The right-eye virtual object and the left-eye virtual object cooperatively create an appearance of a pseudo 3D video perceivable by a user viewing the right and left near-eye displays.
