Abstract

There is provided an information processing apparatus including: a detection unit for detecting pressure applied by user input performed on a touch screen; a determination unit for determining which of two or more input states the user input belongs to, in accordance with the pressure detected by the detection unit; and an operation control unit for enabling or disabling a limitation imposed on operation with a user interface displayed on the touch screen, in accordance with the state of the user input determined by the determination unit.

Claims

1. An electronic device comprising:

a touch screen;

a pressure sensitive sensor configured to detect pressure applied by user inputs with a manipulation object performed on the touch screen; and

circuitry configured to

determine which of two or more input states a first user input of the user inputs belongs to by comparing the detected pressure with a threshold value for a predetermined time;

determine that the first user input belongs to a first input state of the two or more input states when the detected pressure is determined to be more than the threshold value for the predetermined time;

determine that a second user input of the user inputs after the first user input is in the first input state until the pressure is determined to be equal to or less than the threshold value after the determination that the detected pressure of the first user input is more than the threshold value for the predetermined time; and

determine that a third user input of the user inputs is in a second input state of the two or more input states after releasing of the manipulation object from the touch screen.

2. The electronic device of claim 1, wherein the circuitry configured to enable a limitation in the first input state.

3. The electronic device of claim 2, wherein

the limitation is to limit for selecting an item.

4. The electronic device of claim 3, wherein

the limitation is to limit a number of specifiable parameter values to a limited number of candidate values.

5. The electronic device of claim 1, wherein

the electronic device is one of a personal computer, a smart phone, a music player, a game terminal or a digital household appliance.

6. The electronic device of claim 1, wherein

the circuitry is configured to control a display to display a screen corresponding to at least one of a web browser, a digital album, a document editor, an email client, a content player or a game application.

7. A method performed by an electronic device including a touch screen and a pressure sensitive sensor configured to detect pressure applied by user inputs with a manipulation object performed on the touch screen, the method comprising:

determining which of two or more input states a first user input of the user inputs belongs to by comparing the detected pressure with a threshold value for a predetermined time;

determining that the first user input belongs to a first input state of the two or more input states when the detected pressure is determined to be more than the threshold value for the predetermined time;

determining that a second user input of the user inputs after the first user input is in the first input state until the pressure is determined to be equal to or less than the threshold value after the determination that the detected pressure of the first user input is more than the threshold value for the predetermined time; and

determining that a third user input of the user inputs is in a second input state of the two or more input states after releasing of the manipulation object from the touch screen.

8. The method of claim 7, further comprising:

enabling a limitation in the first input state.

9. The method of claim 8, wherein

the limitation is to limit for selecting an item.

10. The method of claim 9, wherein

the limitation is to limit a number of specifiable parameter values to a limited number of candidate values.

11. The method of claim 7, wherein

the electronic device is one of a personal computer, a smart phone, a music player, a game terminal or a digital household appliance.

12. A non-transitory computer-readable medium including computer-program instructions, which when executed by an electronic device including a touch screen and a pressure sensitive sensor configured to detect pressure applied by user inputs with a manipulation object performed on the touch screen, cause the electronic device to:

determine which of two or more input states a first user input of the user inputs belongs to by comparing the detected pressure with a threshold value for a predetermined time;

determine that the first user input belongs to a first input state of the two or more input states when the detected pressure is determined to be more than the threshold value for the predetermined time;

determine that a second user input of the user inputs after the first user input is in the first input state until the pressure is determined to be equal to or less than the threshold value after the determination that the detected pressure of the first user input is more than the threshold value for the predetermined time; and

determine that a third user input of the user inputs is in a second input state of the two or more input states after releasing of the manipulation object from the touch screen.

13. The non-transitory computer-readable medium of claim 12, wherein the computer-program instructions, which when executed by the electronic device, cause the electronic device to:

enable a limitation in the first input state.

14. The non-transitory computer-readable medium of claim 13, wherein

the limitation is to limit for selecting an item.

15. The non-transitory computer-readable medium of claim 14, wherein

the limitation is to limit a number of specifiable parameter values to a limited number of candidate values.

16. The non-transitory computer-readable medium of claim 12, wherein

the electronic device is one of a personal computer, a smart phone, a music player, a game terminal or a digital household appliance.

17. The non-transitory computer-readable medium of claim 12, wherein the computer-program instructions, which when executed by the electronic device, cause the electronic device to:

control a display to display a screen corresponding to at least one of a web browser, a digital album, a document editor, an email client, a content player or a game application.
