Abstract

An information processing device includes a memory, a display device that displays information on a screen, a detection device that detects a tip position of an indicator body on the display device in a state in which the information processing device is held, and a processor coupled to the memory, configured to change a display area displayed on the screen of the display device to an operation area whose vertex is the tip position of the indicator body and which is operable by the indicator body in a state in which the information processing device is held.

Claims

1. An information processing device comprising:

a memory;

a display device that displays information on a screen;

a detection device that detects a tip position of an indicator body on the display device in a state in which the information processing device is held; and

a processor coupled to the memory, configured to change a display area displayed on the screen of the display device to an operation area whose vertex is the tip position of the indicator body and which is operable by the indicator body in a state in which the information processing device is held.

2. The information processing device according to claim 1,

wherein when a first position indicated by a tip of the indicator body at first timing is different from a second position indicated by the tip of the indicator body at second timing that is different from the first timing, the processor is configured to change a first operation area formed according to the first position to a second operation area formed according to the second position and causes the display device to display the second operation area.

3. The information processing device according to claim 1,

wherein the processor is configured to calculate a scale ratio at a position indicated by a tip of the indicator body with respect to a reference position that forms the screen, identify a changed position of an icon in the operation area based on a position of the icon displayed on the screen and the scale ratio, arrange the icon at the changed position, and causes the display device to display the icon.

4. The information processing device according to claim 2,

wherein the processor is configured to reduce and display the operation area in a first direction when either an approach or a touch is detected in the first direction with respect to the second position on a display surface of the display device and reduce and display the operation area in a second direction when either an approach or a touch is detected in the second direction, which is different from the first direction, with respect to the second position on the display surface.

5. The information processing device according to claim 4,

wherein the first direction is a direction toward a lower right corner of the screen and the second direction is a direction toward a lower left corner of the screen.

6. The information processing device according to claim 1,

wherein when the tip position of the indicator body is not on a diagonal line of the screen, the processor is configured to cause the display device to display an operation area having the same ratio of vertical and horizontal sizes as that of the screen according to the tip position of the indicator body with respect to the screen.

7. The information processing device according to claim 1,

wherein the processor is configured to move the display area based on a first position indicated by a tip of the indicator body at first timing and a second position indicated by the tip of the indicator body at second timing that is different from the first timing.

8. The information processing device according to claim 1,

wherein the processor is configured to enlarge the display area based on a first position indicated by a tip of the indicator body at first timing and a second position indicated by the tip of the indicator body at second timing that is different from the first timing.

9. A machine readable medium storing a program that, when executed by a processor, causes the processor to perform operations comprising:

detecting a tip position of an indicator body on a display device in a state in which an information processing device is held; and

changing a display area displayed on the screen of the display device to an operation area whose vertex is the tip position of the indicator body and which is operable by the indicator body in a state in which the information processing device is held.

10. The machine readable medium storing the program according to claim 9,

wherein when a first position indicated by a tip of the indicator body at first timing is different from a second position indicated by the tip of the indicator body at second timing that is different from the first timing, the program causes the information processing device to perform changing a first operation area formed according to the first position to a second operation area formed according to the second position and causing the display device to display the second operation area.
