A motion of the portable terminal is input by measuring an acceleration along the X-, Y- and Z-axes of the portable terminal.

The acceleration along each axis is converted to an equivalent basic-posture acceleration along each axis using the rotation angles. The detected motion of the portable terminal is recognized using the basic-posture acceleration along each axis.
