Abstract
A mobile computer may receive a bluetooth signal from a wireless sensor to determine entrance to a building. The mobile computer may track, on a floor of the building, its indoor position by utilization of a combination of Wi-Fi information and accelerometer information. The indoor position may be tracked without global positioning system (GPS) information and may be associated with a probability related accuracy value.
