Abstract
Physical locations of people and objects have been one of the most widely used context information in context-aware applications. To enable such location-aware applications in the indoor environment, many indoor location systems have been proposed in the past decade, such as Active Badge, Active Bat, Cricket, smart, RADAR, and Ekahau. However, we have seen very limited market success of these indoor location systems outside of academic and industrial research labs. We believe that the main obstacle that prevents their widespread adoption is that they
require certain level of system infrastructural support (including hardware, installation, calibration, maintenance, etc.) inside the deployed environments. Significantly reducing the needed system infrastructure serves as our main motivation to design
and prototype a new footprint location system on traditional Japanese GETA (pronounced "gue-ta") sandals. This footprint location system can compute a user's physical location solely by using sensors installed on the GETA sandals. To enable location tracking, a user simply has to wear the GETA sandals with no extra user setup
and calibration effort. This system works by attaching location sensors, including two ultrasonic-infrared-combo readers and one ultrasonic-infrared-combo transmitter, on the GETA sandals.
