Abstract
A system and method is described that computes an estimated current location for a client device based on both the detected current location and the predicted current location of the client device. By utilizing the predicted current location, the system and method may account for and compensate for anomalies and inaccuracies in the detected current location. Accordingly, the system and method provides a more accurate estimation for the current location of the client device based on examination of heuristics and a priori environmental data. In particular, the system and method compensates for detected locations that are impossible or improbable based on previous locations of the client device, the layout of the environment in which the client device is traversing, data describing the user of the client device, and/or data describing the client device.
