Abstract
A system and method for determining the progress and position of a pedestrian. The shoes of the user are each provided with communicating sensors. The sensors sense when a step has been taken and communicate with each other through Bluetooth, 802.11b, or some other such short-range wireless protocol. This communication includes a distance measurement, and the distance between sensors is calculated and stored with each step, the sensors being in communication with a central processor for this purpose. The sensors also determine their own orientation and their orientation relative to the other sensor, communicating this directional information to the central processor as well. The direction information is used to calculate the direction of travel and, combined with the accumulated distance measurements, the position of a user.
