Abstract
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.
Claims4
A mobile computer comprising:
- a processor, of the mobile computer, is 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 determined with satellite related positioning information;
- the processor further configured to track, with the initial indoor location, data, and estimated motion information from an accelerometer, location in a room in the building;
- wherein the data is a combination of Wi-Fi related position information received via a transceiver and environmental sensor information utilized to determine a floor of the room;
- and
- wherein the location is tracked substantially without satellite related positioning information.
