We present an indoor navigation system, SCAN, which displays the user's current location on a user-scanned indoor map. Smartphones use the global positioning system (GPS) to determine their position on the earth, but it does not work in interior environments. SCAN uses indoor map images scanned by a smartphone camera and displays the user's position on the indoor map while they move around a floor. It tracks the user's position using an inertial measurement unit (IMU) on the smartphone. Camera calibration is required for precise navigation, but our system estimates the user's position based on a single landscape image. Results of our preliminary user study suggest that participants' experiences were similar to using outdoor GPS navigation systems.
