Abstract
Data-processing apparatus and method that provide continuous scrolling on a flat coordinate-input device. Coordinate-information is input by the flat coordinate-input unit. Coordinate-information acquiring unit acquires the input coordinate-information. Coordinate-information storage unit stores the coordinate-information. An angle-calculator calculates an angle defined by i) a displacement-vector between a coordinate shown by the first coordinate-information that is the latest information, and a coordinate shown by the second coordinate-information acquired previous to the latest, and ii) a displacement-vector between the coordinate shown by the second coordinate-information and a coordinate shown by the third coordinate-information acquired previous to the second. The scroll-information generator determines a direction of scrolling and an amount of scrolling from the displacement-vectors and angle. The scroll unit performs scrolling according to the scroll information.
