Abstract
Disclosed are an apparatus for detecting wrist steps and a method thereof, which can exactly detect a user wrist step based on a plurality of acceleration signals. The apparatus includes an acceleration sensor, a controller and a display unit. The acceleration sensor detects a plurality of acceleration signals corresponding to a plurality of axis directions. The controller detects a plurality of wrist step feature points corresponding to the plurality of acceleration signals, detects time periods between the plurality of wrist step feature points, selects any one acceleration signal among the plurality of acceleration signals based on a standard deviation of the time periods, and detects wrist steps corresponding to the selected acceleration signal. The display unit displays the wrist steps.
