PURPOSE: An apparatus and a method for pointing in a 3D space are provided to correct an error of a gyro sensor by using an earth magnetism sensor, thereby inputting a user interface command by accurate spatial pointing. CONSTITUTION: A method for pointing in a 3D space using an input device spatially moving comprises the following steps. Moving displacement or an azimuth according to movement of the input device are measured(S401). The measured moving displacement and azimuth are converted into absolute moving displacement and an absolute azimuth(S403). |
