摘要:
Techniques are provided for synchronization of sensor signals between devices. One or more of the devices may collect sensor data. The device may create a sensor signal from the sensor data, which it may make available to other devices upon a publisher/subscriber model. The other devices may subscribe to sensor signals they choose. A device could be a provider or a consumer of the sensor signals. A device may have a layer of code between an operating system and software applications that processes the data for the applications. The processing may include such actions as synchronizing the data in a sensor signal to a local time clock, predicting future values for data in a sensor signal, and providing data samples for a sensor signal at a frequency that an application requests, among other actions.

A system and method is provided for using motion-capture data to control navigating of a cursor in a user interface of a computing system. Movement of a user's hand or other object in a three-dimensional capture space is tracked and represented in the computing system as motion-capture model data. The method includes obtaining a plurality of positions for the object from the motion-capture model data. The method determines a curved-gesture center point based on at least some of the plurality of positions for the object. Using the curved-gesture center point as an origin, an angular property is determined for one of the plurality of positions for the object. The method further includes navigating the cursor in a sequential arrangement of selectable items based on the angular property.

Methods for recognizing gestures within a near-field environment are described. In some embodiments, a mobile device, such as a head-mounted display device (HMD), may capture a first image of an environment while illuminating the environment using an IR light source with a first range (e.g., due to the exponential decay of light intensity) and capture a second image of the environment without illumination. The mobile device may generate a difference image based on the first image and the second image in order to eliminate background noise due to other sources of IR light within the environment (e.g., due to sunlight or artificial light sources). In some cases, object and gesture recognition techniques may be applied to the difference image in order to detect the performance of hand and/or finger gestures by an end user of the mobile device within a near-field environment of the mobile device.

Techniques for managing virtual ports are disclosed herein. Each such virtual port may have different associated features such as, for example, privileges, rights or options. When one or more users are in a capture scene of a gesture based system, the system may associate virtual ports with the users and maintain the virtual ports. Also provided are techniques for disassociating virtual ports with users or swapping virtual ports between two or more users.

A system is disclosed for providing on-screen graphical handles to control interaction between a user and on-screen objects. A handle defines what actions a user may perform on the object, such as for example scrolling through a textual or graphical navigation menu. Affordances are provided to guide the user through the process of interacting with a handle.

Described herein is technology for, among other things, performing navigation in a media environment. The technology involves the presenting a user with only a portion of the previously visited pages or areas as he or she moves to previously visited pages or areas. As the user moves around the media environment, the movements are recorded for use when requests are received for previously visited areas or pages. As the user moves to previously visited areas redundant pages or areas are skipped. Thus, the user's forward and backward navigation are different and the user moves backward more easily, quickly and efficiently.

A media feed interface may be provided that may be used to extract a media frame from a media feed. The media feed interface may access a capture device, a file, and/or a network resource. Upon accessing the capture device, file, and/or network resource, the media feed interface may populate buffers with data and then may create a media feed from the buffers. Upon request, the media feed interface may isolate a media frame within the media feed. For example, the media feed interface analyze media frames in the media feed to determine whether a media frame includes information associated with, for example, the request. If the media frame includes the requested information, the media feed interface may isolate the media frame associated with the information and may provide access to the isolated media frame.

The technology described herein is a system and methods for generating a branded background for user interfaces. In one embodiment, the background is generated based on a background template. A content partner may customize the background by providing a hue value, artwork and a logo. The background of the user interface is tinted a color associated with the hue value. The artwork and logo is placed in the background, and in one embodiment, the artwork comprises a watermark version of the artwork. Gallery content may also be layered over the background to create a UI having a theme.
