Patent ID: 7259756

Claim:
A method of selecting information in a multi-dimensional space, the method comprising the steps of: (a) sensing the motion of a user for information selection; (b) determining, using the amount of the sensed motion, whether the sensed motion is an effective motion of the intended information selection and returning to step (a) if it is determined that the motion is not the effective motion; (c) determining whether the amount of the sensed motion exceeds a predetermined amount after step (a) and going to step (b) if it is determined that the amount of the motion does not exceed the predetermined amount; (d) if it is determined that the motion is the effective motion in step (b), determining the information selected by the effective motion as effective information; wherein step (b) comprises the sub-steps of: (b1) extracting as a feature amount a portion having a change in the size of the sensing result; (b2) determining whether the feature amount is at least of a predetermined threshold and turning to step (a) if it is determined that the feature amount is less than the predetermined threshold; and (b3) if it is determined that the feature amount is at least of the predetermined threshold, determining that the motion is the effective motion and going to step (d).
