Navigation aid for people (joggers and runners) in the unfamiliar urban environment using inertial navigation

Joggers and runners who have moved to the new urban environment have a fear of getting lost on the path. An aid is needed to move from one place to another. Normally people carry a GPS device which gives the map of the city, by refereeing to that they will continue their travel. For the joggers and runners the traditional way may not be convenient, for each time they have to take out the device wait for the map to load and then decide where to go. The normal GPS accuracy is 2025 meters in urban canyon, multi-path and fading errors of GPS in urban environment result in inaccurate positioning, because of which there is a high probability of losing the path. To overcome this inertial navigation system (INS) is used which is independent of external signals. They can plan their short travel in their homes using google map through the waypoints. Waypoints (WP) have specific latitude, longitude and altitude, which will assist to plan the path. When they deviate from the intended path the vibration motors which are attached to the shoulders of the human will give signals to make them to follow the intended path.
