摘要:
Techniques enable locating a position within a file that corresponds to a desired seek time without having access to an index specifying the desired seek time's position. An iterative process may be used to estimate the position that corresponds to the desired seek time. The process may iterate through multiple estimations until a difference between a time corresponding to an estimated position and the desired seek time is within an acceptable amount or until the process reaches an iteration threshold. The file may then be played beginning at or near the desired seek time. The techniques may therefore allow a user to seek within a file while the user progressively downloads or streams the file.

The present invention is direct to a Live Network Explorer (LNE) which allows users to graphically navigate through a web of interconnected friends on a gaming console. The LNE provides a real-time graphical representation of friend-of-friend relationships, with the currently-viewed user as a visual node in the screen center. The center node is surrounded by nodes representing that user's friends. Real-time animation is used to represent transitions as the user navigates from person to person. The LNE also represents groups as a visual node in this graphically interconnected web so that the user can travel to a group that a person belongs to, and can see all the people inside the group by connections. The user can navigate to any of these people in the group. The user can click on a person to bring up their digital identity details.

Methods for enabling hands-free selection of objects within an augmented reality environment are described. In some embodiments, an object may be selected by an end user of a head-mounted display device (HMD) based on detecting a vestibulo-ocular reflex (VOR) with the end user's eyes while the end user is gazing at the object and performing a particular head movement for selecting the object. The object selected may comprise a real object or a virtual object. The end user may select the object by gazing at the object for a first time period and then performing a particular head movement in which the VOR is detected for one or both of the end user's eyes. In one embodiment, the particular head movement may involve the end user moving their head away from a direction of the object at a particular head speed while gazing at the object.

Embodiments are disclosed that relate to operating a user interface on an augmented reality computing device comprising a display system. For example, one disclosed embodiment includes displaying a virtual object via the display system as free-floating, detecting a trigger to display the object as attached to a surface, and, in response to the trigger, displaying the virtual object as attached to the surface via the display system. The method may further include detecting a trigger to detach the virtual object from the surface and, in response to the trigger to detach the virtual object from the surface, detaching the virtual object from the surface and displaying the virtual object as free-floating.
摘要:
A system and method are disclosed for capturing views of a mixed reality environment from various perspectives which can be displayed on a monitor. The system includes one or more physical cameras at user-defined positions within the mixed reality environment. The system renders virtual objects in the mixed reality environment from the perspective of the one or more cameras. Real and virtual objects from the mixed reality environment may then be displayed from the perspective of the one or more cameras on one or more external, 2D monitor for viewing by others.

Items can be displayed radially by positioning representative icons in a circular or helical fashion on a display. Upon receiving an angle input from a radial input device, an item at a corresponding angle on the display can be selected. The set of selectable items can be recalculated with each new selection, thereby removing the constraint of available display space and allowing easy and continuous traversal of even very large datasets.
