CALIBRATION METHOD CAPABLE OF ENABLING A USER TO INTUITIONALLY RECOGNIZE HORIZONTAL STATE OF THE PORTABLE TERMINAL IN A PORTABLE TERMINAL AT ONCE AND A DEVICE OF THE SAME

摘要

PURPOSE: A calibration method of a portable terminal and a device of the same are provided to enable a user to perform the calibration method of a motion sensor conveniently.;CONSTITUTION: A motion sensor(140) senses gradient information about at least two directions of a portable terminal. A display unit(130) output coordinate which can display at least two information. The display unit outputs gradient information about at least two sensed directions into one image on the coordinate system. A control unit(110) outputs an warning message not to enable a user to move the portable terminal among correcting performance of a motion sensor. The control unit outputs the progress level of correction to the display unit.;COPYRIGHT KIPO 2011
