Abstract

An object of the present invention is to provide a display control system and a display control method which can rotate information displayed on a display screen as intended by a user by performing one rotating operation. A display control system according to the present invention includes: a rotating operation deciding unit which decides whether or not a rotating operation of rotating information in a state where two points are placed in touch with the information displayed on a display screen has been performed; and a display controller which, when the rotating operation deciding unit determines that the rotating operation has been performed, and when a speed of the rotation is a first threshold or more, controls to rotate the information more greatly than actual rotation performed by the rotating operation and to display the information on the display screen.

Claims

1. A display control system comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, performs processes of,

deciding whether or not a rotating operation of rotating information in a state where two points are placed in touch with said information displayed on a display screen has been performed; and

when it is decided that said rotating operation has been performed, and when a speed of said rotation is a first threshold or more, controlling to rotate said information more greatly than actual rotation performed by said rotating operation and to display said information on said display screen.

2. The display control system according to claim 1, wherein, when the speed of said rotation is less than said first threshold, said controlling includes rotating said information following the actual rotation performed by said rotating operation.

3. The display control system according to claim 1, wherein, when the speed of said rotation is said first threshold or more, said controlling includes rotating said information by causing an increase at a fixed rate compared to said actual rotation performed by said rotating operation, causing an increase in proportion to the speed of said rotation, causing an expotential increase according to the speed of said rotation or causing an increase stepwisely according to the speed of said rotation.

4. The display control system according to claim 1, wherein said controlling includes rotating said information based on a distance between said two points, too, and displaying said information on said display screen.

5. The display control system according to claim 4, wherein, when the distance between said two points is a second threshold or more, said controlling includes rotating said information more greatly than the actual rotation performed by said rotating operation.

6. The display control system according to claim 4, wherein, when the distance between said two points is less than said second threshold, said controlling includes rotating said information following the actual rotation performed by said rotating operation.

7. A display control system comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, performs processes of,

deciding whether or not a rotating operation of rotating information in a state where two points are placed in touch with said information displayed on a display screen has been performed; and

when it is decided that said rotating operation has been performed, and when a distance between said two points is a second threshold or more, controlling to rotate said information more greatly than actual rotation performed by said rotating operation and to display said information on said display screen.

8. The display control system according to claim 7, wherein, when the distance between said two points is less than said second threshold, said controlling includes rotating said information following the actual rotation performed by said rotating operation.

9. The display control system according to claim 8, wherein, when the distance between said two points is said second threshold or more, said controlling includes rotating said information by causing an increase at a fixed rate compared to said actual rotation performed by said rotating operation, causing an increase in proportion to the distance between two points, causing an expotential increase according to the distance between said two points or causing an increase stepwisely according to the distance between said two points.

10. A display control method comprising:

deciding whether or not a rotating operation of rotating information in a state where two points are placed in touch with said information displayed on a display screen has been performed; and

when it is decided that said rotating operation has been performed, and when a speed of said rotation is a first threshold or more, controlling to rotate said information more greatly than actual rotation performed by said rotating operation and to display said information on said display screen.

11. The display control method according to claim 10, wherein said controlling is based on a distance between said two points, too.

12. A display control method comprising:

deciding whether or not a rotating operation of rotating information in a state where two points are placed in touch with said information displayed on a display screen has been performed; and

when it is decided that said rotating operation has been performed, and when a distance between said two points is a second threshold or more, controlling to rotate said information more greatly than actual rotation performed by said rotating operation and to display said information on said display screen.
