TRACKING A MOBILE COMPUTER INDOORS USING WI-FI, MOTION, AND ENVIRONMENTAL SENSORS

摘要

A mobile computer determines its initial indoor location in a building. The initial indoor location may be associated with probability related accuracy and selectively determined with satellite related positioning information. The mobile computer may track, by utilization of the initial indoor location, data, and estimated accelerometer based motion information, location on a floor of the building. The data may be a combination of Wi-Fi information and sensor information.
