Abstract
A location-based service includes detecting the relative motion of an on-site resource, such as a shopping cart, in addition to detecting the absolute position of the on-site resource, and displaying information on the on-site resource. The displayed information is based upon the detected relative motion and the detected absolute position. The relative motion is tracked and a position on a floor plan is deduced. This deduced position is adjusted, for example, synchronized or reset, as a function of and in response to the detected absolute position.
