Abstract
Providing indoor location, position, or tracking of a mobile computer is disclosed. Outdoor location, indoor location, and determined motion information is used to track the mobile computer indoors.
Claims18
A mobile computer comprising:
- circuitry configured to send building layout information to a server to generate a map of a building;
- circuitry configured to determine outdoor location of the mobile computer using global positioning system (GPS) data;
- at least one processor configured to determine an initial location of a room in the building that the mobile computer is located, wherein the initial location is determined based on the outdoor location, Wi-Fi information, environmental information or atmospheric information provided by at least one sensor in the mobile computer, and cell tower information;
- and
- the at least one processor configured to track the mobile computer in the building, using the generated map of the building, from the room to another room using the initial location of the room and estimated motion information, wherein the estimated motion information is based on accelerometer and gyroscope information provided to the mobile computer by an accelerometer and gyroscope.
