Abstract:
1. A method of determining a path of travel within a retail or commercial establishment, comprising: generating a measured path of travel of a device in a retail or commercial establishment by determining locations of the device based on signals received at a plurality of different time instances from the device at a plurality of location detectors in the retail or commercial establishment using a first signal type, wherein each location is associated with a zone within the retail or commercial establishment; determining, using a processor, that a first location on the measured path of travel and corresponding to a first time instance may be incorrect by determining that a second location corresponding to a second time instance and a third location corresponding to a third time instance, which are both different from the first time instance, occur in a second zone within the retail or commercial establishment that is different from a first zone corresponding to the first location; based on a fourth time instance associated with a person detection event, selecting a person detector that generated the person detection event and is located at an entrance or exit of the second zone; analyzing the location of the person detector to determine that the first location is incorrect, wherein the person detector generates the person detection event using a second signal type different from the first signal type; and based on the analysis, correcting the first location by changing the first location to a fourth location that is located within the second zone.
