Abstract

A motion detecting device includes an accelerometer configured to generate gravitational acceleration readings associated respectively with consecutive time segments, an angular acceleration sensor and configured to generate angular acceleration readings, and a processor operable in one of a standby mode and an active mode. When operated in the standby mode, the processor activates the accelerometer, deactivates the angular acceleration sensor, and determines whether the user is in a substantial moving state. When determined that the user is in the substantial moving state, the processor switches to the active mode to activate both the accelerometer and said angular acceleration sensor, in order to determine the motion of the user.
