SYSTEMS AND METHODS FOR TRANSFORMING SENSORY MEASUREMENTS OF A HANDHELD DEVICE LOCATED IN MOVING VEHICLE FROM DEVICE'S COORDINATE SYSTEM TO THAT OF A VEHICLE

摘要

A method of operating a general purpose handheld communication device to transform sensory measurements of a handheld device located in moving vehicle from device's coordinate system to that of a vehicle, the handheld communication device including GPS sensor, accelerometer sensor, gyroscope sensor, magnetometer sensor, data processor and data storage medium, the method comprising: identifying a vertical and horizontal acceleration component in car based coordinate system; and identifying strong change in speed and in heading in the car coordinate system; identifying the orientation of the handheld device relative to the vehicle orientation; and transforming sensory measurements of a handheld device located in moving vehicle from device's coordinate system to that of a vehicle, which further enables a detection of driving maneuvers in the car based coordinate system.
