First Claim
Patent Images
1. A method, comprising:
- determining an estimated initial position for a mobile station, wherein the estimated initial position comprises an elevation component;
detecting an interior feature of a building at least in part by detecting a change in position of the mobile station with respect to said estimated initial position in response to sensor data by detecting a change in the elevation component; and
adjusting the detected change in the elevation component using information related to the detected interior feature.
