the circuitry is configured to control the 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. The information processing apparatus of claim 1 , wherein the circuitry is configured to:
compare a detected pressure of the first pressure input to a predetermined threshold value; and
enable the limitation in a case that the detected pressure of the first pressure input exceeds the predetermined threshold value.
8. The information processing apparatus of claim 7 , wherein
the circuitry is configured to not enable the limitation in a case that the detected pressure of the first input does not exceed the predetermined threshold value.
9. A non-transitory computer-readable medium including computer-program instructions, which when executed by an information processing apparatus, cause the information processing apparatus to:
detect a pressure of an input applied to a touch screen;
enable a limitation in response to a first pressure input;
determine a second pressure input, which is subsequent to the first pressure input, as an input with the limitation enabled in a case that the second pressure input satisfies a predetermined condition;
disable the limitation in response to the second pressure input in a case that the second pressure input does not satisfy the predetermined condition; and
control a display to display a graphic indicia when the limitation is enabled.
10. The non-transitory computer-readable medium of claim 9 , wherein
the predetermined condition is a lapse of a predetermined period of time from when the first pressure input was detected.
11. The non-transitory computer-readable medium of claim 10 , wherein the computer-program instructions, which when executed by the information processing apparatus, cause the information processing apparatus to:
control the limitation to be enabled until a lapse of the predetermined period of time from when the first pressure input was detected regardless of a detected pressure of the second pressure input.
12. The non-transitory computer-readable medium of claim 9 , wherein
the information processing apparatus is one of a personal computer, a smart phone, a music player, a game terminal or a digital household appliance.
13. The non-transitory computer-readable medium of claim 9 , wherein
the touch screen is one of a resistive film touch screen, a surface acoustic wave touch screen or an electrostatic touch screen.
14. The non-transitory computer-readable medium of claim 9 , wherein the computer-program instructions, which when executed by the information processing apparatus, cause the information processing apparatus to:
control the 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.
15. The non-transitory computer-readable medium of claim 9 , wherein the computer-program instructions, which when executed by the information processing apparatus, cause the information processing apparatus to:
compare a detected pressure of the first pressure input to a predetermined threshold value; and
enable the limitation in a case that the detected pressure of the first pressure input exceeds the predetermined threshold value.
16. The non-transitory computer-readable medium of claim 15 , wherein the computer-program instructions, which when executed by the information processing apparatus, cause the information processing apparatus to:
not enable the limitation in a case that the detected pressure of the first input does not exceed the predetermined threshold value.
17. A method comprising:
detecting a pressure of an input applied to a touch screen;
enabling a limitation in response to a first pressure input;
determining a second pressure input, which is subsequent to the first pressure input, as an input with the limitation enabled in a case that the second pressure input satisfies a predetermined condition;
