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.
Claims4
A mobile computer comprising:
- a processor, of the mobile computer, configured to determine an initial indoor location of the mobile computer in a building, wherein the initial indoor location is associated with probability related accuracy and selectively determined with satellite related positioning information;
- the processor further configured to track, in part with the initial indoor location, data, and estimated motion information from an accelerometer, location in a room in the building;
- and
- wherein the data is a combination of Wi-Fi related position information and environmental sensor information utilized to determine a floor of the room.
