Techniques for data synchronization policies are described. In one or more implementations, techniques may be employed to set data synchronization (“sync”) policies for devices in a data sync environment. The sync policies specify parameters for sync operations in the sync environment, such as how frequently data sync operations are performed, what types of data are synced to particular devices, how frequently particular types of data are synced, and so on. In implementations, the sync policies consider the number of devices that are participating in a sync environment and attributes of the devices in specifying parameters for sync operations. Data can be synchronized among devices in the sync environment based on the sync policies. 1. A computer-implemented method , comprising:aggregating a set of synchronization policies for devices in a synchronization environment, one or more of the synchronization policies specifying data synchronization parameters based on a number of sync participants in the synchronization environment;synchronizing the set of synchronization policies to the devices; andperforming one or more data synchronization operations among the devices based on the set of synchronization policies.2. A method as described in claim 1 , wherein the one or more synchronization policies specify that a frequency with which data synchronization operations are performed is determined based on a number of the devices that are active in the synchronization environment.3. A method as described in claim 1 , wherein at least one of the synchronization policies specifies that high interest data is to be synced to one or more of the devices more frequently than other types of data.4. A method as described in claim 1 , wherein at least one of the synchronization policies is based on a device type for one or more of the devices.5. A method as described in claim 1 , wherein the synchronization policies are managed by a synchronization service external to the devices ...

Embodiments are directed to a near eye display (NED) system for displaying artificial reality content to a user and to manipulate displayed content items based upon gestures performed by users of the NED system. A user of the NED system may perform a gesture simulating the throwing of an object to “cast” a content item to a target location in an artificial reality (AR) environment displayed by the NED system. The gesture may comprise a first portion in which the user's hand “grabs” or “pinches” a virtual object corresponding to the content item and moves backwards relative to their body, and a second portion in which the user's hand moves forwards relative to their body and releases the virtual object. The target location may be identified based upon a trajectory associated with the backwards motion of the first portion of the gesture. 1.

A near eye display (NED) system is configured to present an augmented reality environment to the user. In addition, the NED system uses an imaging device to detect individuals within a local area, and identify positions of hands of the individuals from which the NED system may be able to detect one or more performed gestures. In response to detecting a predetermined gesture, the NED system displays a user of the NED one or more virtual objects corresponding to the identified first gesture at a location associated with a predetermined portion of the individual's body. The displayed virtual objects may be referred to as “visual flair,” and are used to accentuate, stylize, or provide emphasis to gestures performed by individuals within the local area. 1. A system comprising: an optical assembly having an electronic display that is configured to display images corresponding to virtual objects in accordance with display instructions to a first individual corresponding to a user of the NED;', 'an imaging device configured to capture one or more images of a portions of a local area of the NED; and, 'a near eye display (NED) comprising analyze the one or more captured images using a trained model to identify a plurality of hand poses associated with a hand of a second individual located within the local area different from the first individual;', 'identify a first gesture performed by the hand of the second individual based upon the plurality of identified hand poses, the first gesture corresponding to a predetermined sequence of hand poses over time;', "identify a portion of the second individual's body, based upon the identified first gesture; and", "update the display instructions to cause the electronic display to display, in an augmented reality environment as presented to the first individual via the electronic display, at least a first virtual object indicating the identified first gesture at a location corresponding to the identified portion of the second individual ...

View Activation via Hit Testing in an Asynchronous Windowing System

Номер патента: US20180088767A1. Автор: Albert Hwang, Baris YAZICI, Harley M. Rosnow, Peter Freiling, Ramrajprabu Balasubramanian. Владелец: Microsoft Technology Licensing LLC. Дата публикации: 29-03-2018.
Embodiments provide systems and methods for activating applications in a distributed asynchronous system based on detecting touches on a display. The system detects an input on a display. The input on the display may be, for example, from a human touch or a pointing device. An input state manager executes hit-testing on a visual tree to identify a selected view using the input on the display. The selected view is compared to an active view. A shell in the system is notified when the selected view does not match the active view. The input state manager is then notified if the selected view should be made a new active view. The system instructs an application activation service to activate an application associated with the selected view. An input state manager is notified when the application associated with the selected view has been made an active view.

A computer system supports a protocol to process directional navigation inputs to a host application and its component, to manage which component is currently active to receive input events. A first component determines whether to transfer focus to a second component. The first component initiates the transfer by sending a request to the second component. Further input events are queued. The second component processes the request to determine how to transfer focus within the second component. The second component indicates to the operating system how focus has been transferred. The operating system updates information to reflect the changes in state of the components, and informs the host and component that the state has been updated. Queued input events then can be released for processing according to the changed focus. Where the components are separate, independent processes, the protocol can be implemented through inter-process communication techniques. 1. A computer comprising:a processing system comprising a processing unit and a memory, the processing system executing an operating system and computer programs, the computer programs including a first program element and a second program element, each program element having a state managed by the operating system indicative whether the program element is an active program element, wherein the first program element and the second program element, when executed by the processing system under management of the operating system, are operative to:determine, by the first program element when the first program element is the active program element and in response to receiving a non-spatial input event, whether to request the second program element to process the non-spatial input event;send, by the first program element in response to a determination to request the second program element to process the non-spatial input event, a request to the second program element indicating the non-spatial input event;determine, by ...
