Abstract: Method and apparatus for selecting information in a multi-dimensional space are provided. The method includes the steps of sensing the motion of a user intending to select information, and determining whether the sensed motion is an effective motion intended for information selection and returning to the sensing step if it is determined that the motion is not the effective one.
