Abstract

Using a touch-panel capable of detecting coordinate values of a plurality of points, as well as changes therein, on the display screen, a data block as a target for the information processing is selected based on the coordinate values of a plurality of the points which are specified by the user on the display screen, and is then subjected to a predetermined processing. This allows the user to handle the data through an operation closely simulating actual motion in the real world.
