GAIT Based Inertial Navigation System Using Mobile Sensor

摘要

From the precise location data calculated from satellite signals, Global Positioning System makes itself the effective navigation system in the mobile devices yet the cost of which being the higher energy consumption. Being the energy constrained device, the mobile devices thus need the alternative energy efficient navigation system. The pedometer that counts the foot steps taken by the pedestrian, thereby calculating the average distance covered, when integrated with the device's orientation during locomotion, can pave the way for the pedestrian's navigation system. By increasing the efficiency of pedometer using gait analysis and by taking step vectors rather than simply steps, the effective navigation system for pedestrians can be provided. And, this project aims at such energy efficient less GPS dependent navigation system for pedestrians using the mobile sensors-Accelerometer, Magnetometer and Gyroscope for gait analysis and finding orientation.
