1. A mobile computer characterized in that:
- a processor is configured to determine, by utilization of satellite based positioning information, outdoor location of the mobile computer;
the mobile computer is configured to determine, in part, a location of a room in a building where it is located;
the mobile computer is further configured to track, in part by utilization of the location, data, and estimated motion information, movement in the building;
wherein the location is determined by utilization of accuracy information associated with a probability;
wherein the data is a combination of the outdoor location, Wi-Fi information, and environmental sensor information; and
wherein the estimated motion information is based on accelerometer information and gyroscope information.
