Abstract or Summary
  • The problem of footstep level resolution indoor path tracking and gait velocity lacks a good solution. The current solutions are either prohibitively expensive [4], extremely invasive to deploy [1], or too inaccurate to achieve the sub meter level resolution required to track foot paths. By combining existing pedestrian dead reckoning (PDR) using an inertial measurement unit (IMU) techniques with radio frequency identification (RFID) location updates, one can solve the problem of indoor path tracking. RFID tags placed in the building act as waypoints to correct the error that accumulates over time with PDR, thus yielding a system that can be used for arbitrary amounts of time with a resolution high enough to track individual footsteps.
