Tracking a mobile computer indoors using wi-fi and motion sensor information
View Patent ↗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.
1. 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.
2. The mobile computer of claim 1 further comprising:
the processor further configured to analyze gyroscope related data to determine an orientation of the mobile computer.
3. A method comprising:
determining, by a processor of a mobile computer, 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;
tracking, by the mobile computer, 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.
4. The method of claim 3 further comprising:
analyzing, by the mobile computer, gyroscope related data to determine an orientation of the mobile computer.
