ABSTRACT:
A three-dimensional pointing method is disclosed. In the three-dimensional pointing method of the present invention, a desired point in a three-dimensional space represented on a display apparatus is pointed at based on two-dimensional coordinates of a position that is pointed at by a pen tip of an input pen on a predetermined detection plane, and, based on pen pressure that is pressure applied to the pen tip of the input pen, time for continuing to point or operation of an operation means provided in the input pen. In addition, in the three-dimensional pointing method of the present invention, a depth direction coordinate of a three-dimensional pointer to be displayed in the three-dimensional space is changed according to the pen pressure of the input pen, the time for continuing to point or the operation of the operation means provided in the input pen, and the three-dimensional pointer is displayed.
