Method and apparatus for selecting information in multi-dimensional space

The information on the selection method and apparatus of the multi-dimensional space is disclosed. The method comprises the steps of sensing the user's motion to be selected information; (B) filtering through the sensing result of the motion range, and extracts a feature value of the band-pass filtered result; (C) determining when the amount of the feature is determined to be less than said predetermined threshold amount is determined, and the feature of applying less than a predetermined threshold, the step of proceeding to the step (a) and (d) the feature amount is equal to or higher than the predetermined threshold If, by determining that the movement of the effective movement intended selection of said information, it characterized in that it comprises the step of determining a valid information of the selected information by the valid movement. Therefore, the predetermined threshold can be up accurately detected if any one of to set the value, and to undergo to overcome the difficulties any small movement also receive the influence of gravity and the offset, a spatial or a planar user motion information It is a valid movement for selecting and a valid motion can accurately determine the applied at least two or more motion any motion portion of the movement sections, so to achieve a high recognition rate and high reliability of the information, as well as user to more easily select the information It can have the effect of so.
