Abstract
A walk detection method for detecting a motion state of a user includes: measuring a number of triaxial components of gravitational acceleration vector of the device; calculating a triaxial angular velocity of the device; recording data inputs of the triaxial angular velocity, and recording the data inputs not larger than a filtered threshold as effective data inputs; calculating a mean of effective data inputs; calculating a difference value between the effective data inputs and a mean thereof; and determining that, when the difference value is smaller than a threshold of walking state, the user is in a walking state. Otherwise, the user is determined to be in a shaking state at the same location.
