APPRATUS AND METHOD FOR MEASURING WALKING DISTANCE

摘要

An apparatus and a method for measuring a walking distance are provided to determine a mounting position thereof according to whether a walking is detected based on an output signal from a gyro-sensor. An apparatus for measuring a walking distance includes a walking detector(32), a mounting position detector(34), and a walking distance estimator(36). The walking detector is supplied with outputs from an accelerator(20) and a gyro-sensor(40) and detects walking with an acceleration signal and an angular signal from the gyro-sensor. The accelerator is capable of detecting acceleration on at least two axes. The gyro-sensor outputs an angular velocity on roll, pitch, and yaw axes. A mounting position detector determines the position of a portable terminal based on the walking detection. The walking distance estimator estimates the walking distance using coefficient of walking distance estimation parameter which is different according to the position of the portable terminal.
