INFORMATION PROCESSING DEVICE HAVING DETECTOR CAPABLE OF DETECTING COORDINATE VALUES, AS WELL AS CHANGES THEREOF, OF A PLURALITY OF POINTS ON DISPLAY SCREEN

摘要

Using a touch-panel (16) capable of detecting coordinate values of a plurality of points (a, b), as well as changes therein, on the display screen (15), a data block as a target for the information processing is selected based on the coordinate values of a plurality of the points (a, b) which are specified by the user on the display screen (15), 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.
