Abstract:
1. A display device comprising: a touch panel that displays a screen and receives a predetermined input; a detection unit that detects a start point and an end point of a physical touch on the touch panel; and a display control unit that calculates a moving direction of the touch on the basis of the detection result from the detection unit, wherein the display control unit calculates a vector extending from the start point to the end point as the moving direction, enlarges the screen displayed on the touch panel when the moving direction is in a predetermined first range, and reduces the screen when the moving direction is in a predetermined second range different from the first range, the first and second ranges are obtained by dividing a surrounding area of the start point, and the display control unit calculates the moving speed of the touch on the basis of the detection result from the detection unit, enlarges the screen displayed on the touch panel when the moving speed is equal to or greater than a predetermined threshold value and the moving direction is in the first range, and reduces the screen when the moving speed is equal to or greater than the predetermined threshold value and the moving direction is in the second range.
