1. A graphical user interface that facilitates inferring motion and locating a mobile wireless device, the interface comprising:

  • an input component for receiving management information, the management information associated with at least the processes of measuring signal strength data of identified locations and generating probability data of the identified locations to further determine a new location of the wireless device, the probability data includes an inferred likelihood that the wireless device is in motion, an expected velocity of the wireless device, and at least one transition probability that the device is transitioning between two of the identified locations, wherein the determination of a new location is based upon the inferred likelihood that the wireless device is in motion, the expected velocity of the wireless device, the at least one transition probability that the device is transitioning between two of the identified locations, and feasible movement information of the mobile wireless device derived from building layout information of a building in which the mobile wireless device is currently located, wherein the feasible movement information is based on at least one travel path between the two identified locations along which a user carrying the device can physically traverse in the building; and

    a presentation component for presenting a representation of the identified locations to facilitate user interaction therewith, wherein the presentation component further includes a plotting feature for providing a graphical representation of all of the identified locations to which the wireless device may travel, and possible paths that the wireless device may traverse to the identified locations.
