摘要:
Mechanical surface of rotational elements for motion compensation of a locomotive object. A single layer of rotational elements formed as a mechanical surface on which a human can stand and/or move, and which automatically compensates for diverse human locomotion such as translation in two dimensions and rotation. The surface can be used to actively sense and compensate for varying speeds of human motion while in locomotion on the surface. The layer allows a user to move freely within a confined area and to be maintained within the confined area via motion compensation. Thus, the surface is particularly suited for immersion visualization environments where user motion on the surface is translated into user navigation through a virtual environment such as for computer games and simulation without necessitating constraints on immersive scene projection or participant motion.

Positional information is provided while minimizing the possibility that personally identifiable information can be derived therefrom. Positional information is received in the form of trails that can be aggregated. Individual cells of a grid reflect a quantity of aggregated trails through those cells, an average intensity and direction of movement through those cells, or a more detailed distribution thereof. Alternatively, individual trails are aggregated to an aggregated trail in the form of a line. Further obfuscation of personally identifiable information occurs by resampling aggregated positional information, by introducing false positional information, or by falsely modifying existing positional information, in a manner that does not impact the overall aggregations, and by pruning, or deleting, positional information, especially around sensitive locations, such as a user's home, place of business, or other location that users typically would seek to keep private. Provision of positional information is delayed until a sufficient amount is received.

Technologies are described herein for validating and correcting map data using oblique images or aerial photographs taken at oblique angles to the earth's surface. Pixels within oblique images can be analyzed to detect, validate, and correct other sources of data used in generating maps such as vector data, elevation maps, projection parameters, and three-dimensional model data. Visibility and occlusion information in oblique views may be analyzed to reduce errors in either occluding or occluded entities. Occlusion of road segments due to foliage, z-ordering of freeways, tunnels, bridges, buildings, and other geospatial entities may be determined, validated, and corrected. A learning algorithm can be trained with image-based descriptors that encode visible data consistencies. After training, the algorithm can classify errors and inconsistencies using combinations of different descriptors such as color, texture, image-gradients, and filter responses.

Described herein is a technique for customizing device behavior based on evaluated relationships between a user and the user's environment. User conduct is analyzed based on available sensors, which may include user-facing cameras. The user's environmental context is similarly evaluated based on the available sensors. Conduct and context, as well as any identified relationships between such conduct and context, may be reported to application programs, and may form the basis for customized device behavior.

Embodiments of the present invention relate to systems, methods and computer storage media for associating a known geographic location with a known identity. Feature matching, of at least two images, is performed in at least two iterations. The iterations are based on an orientation of feature vectors associated with points of interest in each image. A geometric model is applied to the matched points of interest to improve the matched pairs. Two images are identified as being related. As a result, the known geographic location is associated with the known identity. Additional embodiments include augmenting feature vectors with a coordinate location of a related point of interest based on a geometric model. Further, an exemplary embodiment includes an additional matching iteration based on the augmented feature vectors. In an exemplary embodiment, the feature matching utilizes a Scale-Invariant Feature Transform (SIFT).

Techniques for secure federation of data communications networks are provided. The techniques employ an edge proxy server to route messages depending on a federation mode. In Direct federation mode, an edge proxy server of a network is configured to exchange messages with a specified set of entities, such as other networks, servers, other devices, or users. In Automatic federation mode, an edge proxy server may accept all incoming messages from entities that have a valid certificate. In Clearinghouse federation mode, the edge proxy server forwards all outgoing messages to a specified, trusted clearinghouse server.

Systems and methods are described herein that cause data from asynchronous data sources to be provided with a timestamp that corresponds to a common time base. A trigger board can be used to control synchronized data sources, and can generate timestamps when data is collected by the synchronized data sources. Unsynchronized data sources can generate data independent of the trigger board. System timestamps are generated each time data from the synchronized data source and the unsynchronized data source is received. Values of the system timestamp can be modified, and can be replaced by timestamps that correspond to the time base used by the trigger board.

Provided is a single repository for capturing, connecting, sharing, and visualizing information based on a geographic location, for example. Detailed information of a structure or object information can be displayed on a rooftop or over an area of interest. The detailed information can be provided for a single structure or for each structure shown on a map area. According to an embodiment is a system that facilitates surface overlay and bounding on a map. The system can include a receiver component that receives information for an object, a boundary component that ascertains a perimeter of the object, and a rendering component that selectively displays the object information and object on a map based in part on a user perspective.
