Methods and systems for indoor navigation utilize a smartphone equipped with various sensors. When a person whose initial position is unknown, and in some circumstances whose sight has been impaired, specifies a destination, the navigation system will calculate the coordinates of his/her present location from the sensor readings. It will then calculate the distance to be traveled to the destination and form routes to direct him/her towards the desired location. These steps are carried out using sensor readings and in some cases magnetic maps of the interiors of buildings stored on the smartphone. In some cases dynamic time warping (“DTW”) is used to align a recorded signature of the person's movement through the building with a stored magnetic map in order to identify the person's location within the building. |
