Abstract

A display method executed by a computer, includes: receiving a first input relating to a first operation performed on a display content displayed in a display unit; receiving a second input relating to a second operation performed on the display content; and when the second input received after the first input is a drag operation, changing a display scaling factor of the display content on the basis of a movement direction of the drag operation and a distance between a reference position relating to at least one of the first input and the second input, and a current position of the drag operation.

Claims

1. A display method executed by a computer, comprising:

receiving a first input relating to a first operation performed on a display content displayed in a display unit;

receiving a second input relating to a second operation performed on the display content; and

when the second input received after the first input is a drag operation, changing a display scaling factor of the display content on the basis of a movement direction of the drag operation and a distance between a reference position relating to at least one of the first input and the second input, and a current position of the drag operation.

2. The display method according to claim 1, further comprising:

calculating a movement distance of an input position during continuation of the second input; and

on the basis of the movement distance, determining whether or not the second input is based on the drag operation.

3. The display method according to claim 2, further comprising:

counting a frequency of input operations relating to operations performed on the display content,

wherein, when the frequency is greater than or equal to two and the movement distance is greater than or equal to a threshold value, the determining determines that the second input is the drag operation.

4. The display method according to claim 3, further comprising:

scrolling the display content when the frequency is one.

5. The display method according to claim 1, wherein the reference position is an average coordinate of a plurality of coordinates input by the first input and the second input or at least one coordinate of the plurality of coordinates.

6. The display method according to claim 1, further comprising:

calculating the display scaling factor on the basis of a value obtained by linearly transforming the distance between the reference position and the current position in a certain axis direction,

wherein the changing enlarges or reduces the display content on the basis of the display scaling factor.

7. The display method according to claim 1, further comprising:

during continuation of the drag operation relating to the second input, performing, in the display unit, guide display that indicates a first direction in which the display content is enlarged and a second direction in which the display content is reduced.

8. The display method according to claim 1, further comprising:

cancelling the changing of the display scaling factor when the movement direction of the drag operation has been changed from one of a first direction in which the display content is enlarged and a second direction in which the display content is reduced to another direction during continuation of the second input.

9. The display method according to claim 1, wherein, when a time from reception of the first input to reception of the second input falls within a given time, the changing changes the display scaling factor.

10. The display method according to claim 1, further comprising:

receiving a third input relating to a third operation performed on the display content; and

rotating the display content when the third input is another drag operation different from the drag operation and the another drag operation indicates circular arc-shaped movement.

11. A computer-readable recording medium storing a display program for causing a computer to execute a process, the process comprising:

receiving a first input relating to a first operation performed on a display content displayed in a display unit;

receiving a second input relating to a second operation performed on the display content; and

when the second input received after the first input is a drag operation, changing a display scaling factor of the display content on the basis of a movement direction of the drag operation and a distance between a reference position relating to at least one of the first input and the second input, and a current position of the drag operation.

12. An information processing device comprising:

a memory; and

a processor coupled to the memory and configured to

receive a first input relating to a first operation performed on a display content displayed in a display unit and a second input relating to a second operation performed on the display content, and

when the second input received after the first input is a drag operation, change a display scaling factor of the display content on the basis of a movement direction of the drag operation and a distance between a reference position relating to at least one of the first input and the second input, and a current position of the drag operation.

13. The information processing device according to claim 12, wherein the processor is further configured to calculate a movement distance of an input position during continuation of the second input, determine whether or not the second input is based on the drag operation, on the basis of the movement distance.

14. The information processing device according to claim 13, wherein the processor is further configured to count the frequency of inputs relating to operations performed on the display content, and when the frequency is greater than or equal to two and the movement distance is greater than or equal to a threshold value, determine the second input is the drag operation.

15. The information processing device according to claim 14, wherein the processor is further configured to scroll the display content when the frequency is less than two.

16. The information processing device according to claim 12, wherein the reference position is an average coordinate of a plurality of coordinates input by the first input and the second input or at least one coordinate of the plurality of coordinates.

17. The information processing device according to claim 12, wherein the processor is further configured to calculate the display scaling factor on the basis of a value obtained by linearly transforming the distance between the reference position and the current position in a certain axis direction, and enlarge or reduce the display content on the basis of the display scaling factor.

18. A display method executed by a computer, comprising:

scrolling a display content on a display when a drag operation performed on the display is an operation in a first state after a tap operation performed on the display, while changing a display scaling factor of the display content when the drag operation is an operation in a second state after the tap operation.

19. A display method executed by a computer, comprising:

scrolling a display content on a display on the basis of a drag operation performed on the display in a first state after a tap operation performed on the display; and

changing a display scaling factor of the display content on the basis of the drag operation in a second state after the tap operation.

20. A display method executed by a computer, comprising:

setting one of a first mode in which a display content is scrolled and a second mode in which a display scaling factor of the display content is changed, on the basis of a time interval between a first tap operation performed on a display and a second tap operation that is performed on the display and follows the first tap operation; and

displaying the display content on the display in response to a drag operation including the second tap operation, in accordance with one of the first mode and the second mode set by the setting.
