摘要： [PROBLEM TO BE SOLVED] To provide a movement locus detector capable of detecting the movement locus at the both low speed and high speed by using a magnetic detection section and an acceleration detection section. [SOLUTION] In the movement locus detector, a standard X-axis, a standard Y-axis, and a standard Z-axis are preliminarily being decided, and a magnetic detection section 2 for detecting magnetism in each axis direction and an acceleration detection section 12 for detecting the acceleration in each axis direction are mounted. At the low speed running, a movement distance is obtained from the number of footsteps detected by the acceleration detection section 12, and a movement locus is obtained from an azimuth of a geomagnetic vector detected by the magnetic detection section 2. At the high speed running, an angular velocity change of the geomagnetic vector is detected from the magnetic detection section 2, and the movement locus is obtained from the detection output.

摘要： PROBLEM TO BE SOLVED: To provide a portable terminal device and a portable terminal system capable of implementing calibration of orientation sensors correctly.
SOLUTION: The portable terminal device 1 having an orientation sensor is fixed to a holder 3 on board to connect with a car navigation device 2 through a telecommunication cable 4. The portable terminal device 1 receives orientation information detected at the car navigation device 2 and calibration of the orientating sensor is started at the time when received orientation information becomes more than 90-degree. On the other hand, calibration utilizes not only the magnetic field data detected by the orientating sensor of portable terminal device 1 but also orientation information of higher reliability received from the car navigation device 2.
