摘要： Mobile camera localization using depth maps is described for robotics, immersive gaming, augmented reality and other applications. In an embodiment a mobile depth camera is tracked in an environment at the same time as a 3D model of the environment is formed using the sensed depth data. In an embodiment, when camera tracking fails, this is detected and the camera is relocalized either by using previously gathered keyframes or in other ways. In an embodiment, loop closures are detected in which the mobile camera revisits a location, by comparing features of a current depth map with the 3D model in real time. In embodiments the detected loop closures are used to improve the consistency and accuracy of the 3D model of the environment.

摘要： Real-time camera tracking using depth maps is described. In an embodiment depth map frames are captured by a mobile depth camera at over 20 frames per second and used to dynamically update in real-time a set of registration parameters which specify how the mobile depth camera has moved. In examples the real-time camera tracking output is used for computer game applications and robotics. In an example, an iterative closest point process is used with projective data association and a point-to-plane error metric in order to compute the updated registration parameters. In an example, a graphics processing unit (GPU) implementation is used to optimize the error metric in real-time. In some embodiments, a dense 3D model of the mobile camera environment is used.

摘要： A method and system for preloading data is provided. Resources are preloaded on a client before they are needed by an application. Application hints and static resources lists may be used to indicate resources are needed. The application may begin execution before receiving all of the resources associated with the application. Preloading may be done during execution of an application, or when the application is not executing. Preloading allows an application to run smoothly without consuming more resources than are needed by an application. A prediction graph may be generated that is used in predicting the resources that are likely to be needed by the application. An analyzer may also be used to simulate the system and adjust parameters used in creating the prediction graph.

摘要： A method and system are directed towards enabling content security in a distributed environment. The system includes a data store for content associated with an application that may be tagged as exclusively memory resident at a client. The content may also be encrypted and digitally signed. When an authenticated client requests the content, it is provided at a constrained rate that enables a portion of the content to start execution on the client before the application associated with the content is completely downloaded. Additional portions of the content are provided to the client when the additional portions are required for execution by the application.

摘要： A method and system for granting access to system and content is provided. A key is provided that allows access by a client computer to content that includes a plurality of resources. A server is accessed and the key is provided to the server. Based on the key, access is granted to the content. A program on the client computer requests a resource of the plurality of resources. If the resource is located locally, the resource is provided to the program. Otherwise, the resource is downloaded from the content server and stored locally. A data structure is modified to indicate that the resource is stored locally and the resource is provided to the program.

摘要： A method and system for effectively communicating file properties and directory structures within a distributed file system is provided. A manifest that includes properties relating to all of the files used in an application is created. The manifest is distributed to a client before the client has received all of the files or properties associated with an application. The manifest is stored on the client and is used to determine properties and locations of files used within the application. A distributed file system layer is used to receive file and property requests from the application; determine the location of the requested file, or the property using the manifest, and retrieve the property or file using the manifest. A tool may be used to generate the manifest manually or automatically. File system calls within an application may be replaced with calls that use the distributed file system layer. An interpreter may also be used to intercept the file system calls and replace them with calls that use the distributed file system layer.

摘要： A method and system are directed towards balancing loads on an authentication system. The system employs a first authentication server that is configured to authenticate a user. The system includes a master authentication server. When the master authentication server determines that a load on it has reached a pre-determined value, a data store associated with the master authentication server is partitioned between authentication servers that assume a master authentication server role for its partition of the data store. In one embodiment, each new master authentication server is further enabled to partition its respective partition of the data store, if their respective loads reach the pre-determined value.
