摘要： A method, schema and computer system for a location service provides data structures that are extensible by allowing different types of location awareness applications to retrieve and deposit location data. The method includes providing an abstract location object arranged in a schema to enable servicing a received request for a logical location of an electronic endpoint; and arranging one or more location elements within the context of the abstract location object. The location elements are configured to act as peers relative to the logical location and each location element is configured to act as a proxy relative to any other location element within the abstract location object.

摘要： A user can be provided a variety of incentives to take a route that is different from a standard path in order to relieve path load balancing issues. Information on a primary path can be collected and analyzed to determine if it would be beneficial to encourage users to take an alternate path. If it is determined that users should be encouraged to take another path, then analysis of potential users can occur. A result of the user analysis can be used to select users that are offered to take the alternate path as well as an incentive offered to the user to encourage her to take the alternate path.

摘要： Routes can be produced based on safety characteristics of paths that are included in the route. Safety characteristics can include how susceptible an area surrounding a path is to crime as well as traffic data, such as how many automobile accidents take place on average. Various amounts of safety information can be gathered and a particular path can be assigned a safety score. Analysis can run on different path combinations that would take a user from a starting point to an intended destination. A route can be produced based on the safety score alone, such as a route with a lowest score, based on the safety score with other factors such as anticipated traffic, and the like.

摘要： An image background maintenance system and method for maintaining a background model of an image sequence by processing on multiple spatial scales. These multiple spatial scales include a pixel scale, a regional scale and a frame scale. The image sequence undergoes pixel processing that determines a current background model and provides an initial pixel assignment as either a background or a foreground pixel. Region processing further refines the initial pixel assignments by considering relationships between pixels and possibly reassigning pixels. Frame processing further refines the current background model by determining whether a substantial change has occurred in the actual background and, if so, providing a more accurate background model.

摘要： An interactive map-based game is provided for populating a landmark database with commonly known landmarks. A game session can provide a user with a number of maps that can be presented in succession. Each map presented can be a map segment that is a function of a latitude/longitude pair and a zoom level. A user can enter the names of landmarks believed to be contained in the map segment. If the name entered matches a name within a landmark database, points can be awarded. Once a threshold level of positive confirmations of a landmark name are received, the landmark can be marked as taboo and further entries of that landmark name can be disregarded or minimal points can be awarded for the entry.

摘要： A location system for locating and determining the motion and velocity of a wireless device. The methods include direct inferences about whether a device is in motion versus static based on a statistical analysis of the variation of radio signal strengths over time. The system is trained according to a sparse set of identified locations from which signal strengths are measured. The system uses the signal properties of the identified locations to interpolate for a new location of the wireless device. The system uses a probabilistic graph where the identified locations of the floor plan, expected walking speeds of pedestrians, and independent inference of whether or not the device is in motion are used to determine the new location of the device.

摘要： A mapping application that returns results for a target location as a function of at least one nearby landmark. The one or more nearby landmarks can be selected based on an expected user familiarity with the landmark, a precision of the landmark and/or a spatial relationship of the landmark with respect to the target location. Although landmarks are an integral aspect of navigation, they have rarely been used within electronic navigation devices. Electronic navigation means for a mobile device or other devices can guide the user along a route using photographs of landmarks together with audio and text instructions that reference these landmarks. This can assist older users who often find their mobility hampered by declines in sensory, cognitive and motor abilities.

摘要： A destination analysis module is described which estimates at least one destination of a user given a partial path taken by the user within a geographic area. The destination analysis module operates by detecting a mode of transportation that a user uses to traverse the path (e.g., automobile, public transportation, walking, etc.). The destination analysis module then loads a model associated with the mode of transportation into a destination prediction module and estimates at least one destination based on the path and the model. The model has various components that depend on the mode of transportation, such as routing network information and prior probability information.
