Abstract:
1. A portable terminal having a motion detection function, comprising: a motion detector for measuring an acceleration along an X-, Y- and Z-axis of the portable terminal; and a controller for calculating rotation angles along the X- and Z-axes in a current posture of the portable terminal with respect to the X- and Z-axes in a basic posture of the portable terminal using the acceleration along the X-, Y- and Z-axes, converting the acceleration along the X-, Y- and Z-axes measured between the time the acceleration is higher that a threshold acceleration and a motion completion time to an equivalent basic-posture acceleration along the X-, Y- and Z-axes using the rotation angles, and recognizing a motion of the portable terminal using the basic-posture acceleration along the X-, Y- and Z-axes.
