Abstract
Adaptive mobile device navigation system, methods, and apparatus provide location information for a mobile device performing location estimation using dead reckoning. Multiple estimation modes can be selected including a mode for restricting measured movements to surrounding streets. Updated location fixes can be obtained through turn comparison with surrounding map information and user feedback. User feedback prompts can include photographs having geographic tag information corresponding to locations near an estimated location of the device.
