摘要
PURPOSE: A touch screen control method, a recording medium, a touch screen controller, and a mobile device thereof are provided to effectively proceed a zoom command only with one hand by proceeding the establishment of a center and the zoom command through one continuous touch dragging gesture. CONSTITUTION: A touch sensor(310) detects a dragging gesture operated on a touch screen. A calculation unit(320) calculates a center of a virtual circle with the fixed curvature radius from the first dragging gesture with the fixed curvature radius among the dragging gestures. The calculation unit calculates the distance between a touch point of the second dragging gesture which is continuous in the first dragging gesture and the center. A controller(330) proceeds a zoom command about an object of the touch screen according to the distance.
