摘要:
The claimed subject matter relates to an architecture that can employ vision-monitoring techniques to enhance an experience associated with elements of a local environment. In particular, the architecture can establish gaze- or eye-tracking attributes in connection with a user. In addition, a location and a head or face-based perspective of the user can also be obtained. By aggregating this information, the architecture can identify a current field of view of the user, and then map that field of view to a modeled view in connection with a geospatial model of the environment. In addition, the architecture can select additional content that relates to an entity in the view or a modeled entity in the modeled view, and further present the additional content to the user.

Embodiments enable the evaluation of injected queries within a monad. One or more operators with closures are received from a first process. The operators with closures represent one or more functions to be applied by a second process. The second process evaluates the received operators with closures to apply the functions within the monad. During evaluation, the second process converts the closures to simply typed closures. Further, the second process binds the converted closures within the monad to restrict execution of the functions. In some embodiments, the queries (e.g., sequences of one or more operators with closures) are composed using a set of query operators from the language integrated query (LINQ) framework encoded in uniform resource locators (URLs) in the representational state transfer (REST) style.

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.

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).

Provided is a single repository for capturing, connecting, sharing, and visualizing information based on a geographic location, for example. Provided is a schema, repository, index, and APIs for any information, place, entity, attribute, service or person that can be referenced geographically. A system to provide real time image data includes an input component that receives image data associated with a specific geographic area, a splitter component that splits the image data into at least two quadrants, and a storage component that stores at least a portion of the at least two quadrants. Also provides is on-line or real-time advertising based on a user's mapped location and/or a user preference.
