Abstract
It is intended to enable enlarging or reducing a screen with a simple operation. A mobile phone 1 includes a touch panel 11 that displays a screen and receives a predetermined input, a detection unit 12 that detects a start point and an end point of a physical touch on the touch panel 11, and a display control unit 13 that calculates a moving direction of the touch on the basis of the detection result, enlarges the screen displayed on the touch panel 11 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.
Claims9
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.
A screen display method executed by a display device including a touch panel that displays a screen and receives a predetermined input, the screen display method comprising:
- a detection step of detecting a start point and an end point of a physical touch on the touch panel;
- and
- a display control step of calculating a moving direction of the touch on the basis of the detection result in the detection step, wherein
- the display control step includes:
- calculating a vector extending from the start point to the end point as the moving direction;
- calculating the moving speed of the touch;
- enlarging the screen displayed on the touch panel when the moving speed is equal to or greater than a predetermined threshold value and when the moving direction is in a predetermined first range;
- and
- reducing the screen when the moving speed is equal to or greater than the predetermined threshold value and when the moving direction is in a predetermined second range different from the first range, wherein
- the first and second ranges are obtained by dividing a surrounding area of the start point.
