A computing device and method are provided for transmitting a relevant subset of map data, called a neighborhood, to enable mutual spatial understanding by multiple display devices around a target virtual location to display a shared hologram in the same exact location in the physical environment at the same moment in time. The computing device may comprise a processor, a memory operatively coupled to the processor, and an anchor transfer program stored in the memory and executed by the processor.

Sharing neighboring map data across devices

A file access request is received from an application. One or more file types for the file access request are identified, and one or more file hosts supporting files of the identified one or more file types are also identified. A user interface is displayed, the user interface including a hosted area. Within the hosted area, at least one of the one or more file hosts displays a portion of the user interface identifying one or more files of at least one file host that can be selected for retrieval, or one or more locations that can be selected to which the one or more files are saved.

File access with different file hosts

A mixed reality display system determines a shared coordinate system that is understood by a mixed reality application running on the mixed reality display system and an operating system of the mixed reality display system. The operating system can display a system user interface (UI) element in a mixed reality environment. The system UI element can be displayed at a location in a mixed reality environment. The location is specified by the mixed reality application according to the shared coordinate system. A size and orientation for displaying the system UI element may also be specified. Also, the location, size and orientation may be specified through application program interfaces (API) of the operating system. API calls may be made per frame to adjust the location, size or orientation per frame of the displayed mixed reality environment.

Mixed reality system user interface placement

To ensure that the contents of a non-volatile memory device cache may be relied upon as accurately reflecting data stored on disk storage, it may be determined whether the cache contents and/or disk contents are modified during a power transition, causing cache contents to no longer accurately reflect data stored in disk storage. The cache device may be removable from the computer, and unexpected removal of the cache device may cause cache contents to no longer accurately reflect data stored in disk storage. Cache metadata may be managed during normal operations and across power transitions, ensuring that cache metadata may be efficiently accessed and reliably saved and restored across power transitions. A state of a log used by a file system may be determined prior to and subsequent to reboot of an operating system in order to determine whether data stored on a cache device may be reliably used.

Method and system for ensuring reliability of cache data and metadata subsequent to a reboot

A computing device is provided, including a display configured to display a plurality of holograms superimposed upon a physical environment. The computing device may further comprise a processor configured to store in non-volatile memory a representation of the physical environment, including a plurality of hologram anchors indicating locations at which the holograms are displayed. The processor may store a priority level of each hologram anchor, wherein each priority level is selected from a plurality of priority levels including a high priority level and a low priority level, and wherein at least one hologram anchor has the low priority level. The processor may determine that a total size of the plurality of hologram anchors exceeds a predetermined size threshold. The processor may, for at least one hologram anchor assigned the low priority level, delete that hologram anchor from the representation of the physical environment.

Hologram anchor prioritization

Aspects of the subject matter described herein relate to file system placeholders. In aspects, placeholders may be used by a client to represent remote file system objects. The placeholders may include metadata and may also include none, some, or all of the content of the represented remote file system objects. In response to a request to access content of a file system object represented by a placeholder, a client may obtain needed data from a remote storage system and stream or not stream the data to the requesting application based on whether the requesting application is capable of streaming the data.

Streaming content and placeholders

Embodiments of the present invention provide a schema to describe the structure of a data store that may be used to query the data store. The schema may include a property description describing static and contextual attributes of a property of the data store. The schema may also include a property reference describing contextual attributes of a property of the data store, while referencing static attributes from a property description in another schema. In some instances, the schema may further describe item types and/or kinds for the data store.

Schema for federated searching

Embodiments of the invention provide techniques for managing cache metadata providing a mapping between addresses on a storage medium (e.g., disk storage) and corresponding addresses on a cache device at data items are stored. In some embodiments, cache metadata may be stored in a hierarchical data structure comprising a plurality of hierarchy levels. When a reboot of the computer is initiated, only a subset of the plurality of hierarchy levels may be loaded to memory, thereby expediting the process of restoring the cache metadata and thus startup operations. Startup may be further expedited by using cache metadata to perform operations associated with reboot. Thereafter, as requests to read data items on the storage medium are processed using cache metadata to identify addresses at which the data items are stored in cache, the identified addresses may be stored in memory. When the computer is later shut down, instead of having to transfer the entirety of the cache metadata from memory to storage, only the subset of the plurality of hierarchy levels and/or the identified addresses previously loaded to memory may be transferred (e.g., to the cache device), thereby expediting the shutdown of the computer.
