Abstract

When a detecting unit detects an operation of a key which is not included in a combination predicted by a prediction unit, an input control unit invalidates the operation of the key. Therefore, even if a user wrongly presses a key, the wrong pressing is invalidated, as a result key input intended by the user becomes smooth.

Claims

1-8. -8. (canceled)

9. An input device for performing an input by a plurality of keys operated simultaneously, comprising:

detecting means for detecting a state of keys;

memory means for storing a combination of keys operated simultaneously, which corresponds to a predetermined input;

prediction means for predicting a combination of keys, according to said detected state of keys by said detecting means and said stored combination of keys in said memory means; and

input control means for controlling keys, so that an operation for a key, which is not included in said predicted combination by said prediction means, is invalid.

10. The input device according to claim 9, further comprising

display means for displaying said predicted combination by said prediction means.

11. The input device according to claim 9, wherein

said prediction means predicts a combination of keys, when said detecting means detects a change in the state of keys.

12. The input device according to claim 10, further comprising

highlight display means for displaying a key included in said predicted combination by said prediction means, so as to have a different feature from a key, which is not included in said predicted combination.

13. An information processing apparatus for performing an information processing according to an input, comprising an input device for performing said input by a plurality of keys operated simultaneously, said input device including:

detecting means for detecting a state of keys;

memory means for storing a combination of keys operated simultaneously, which corresponds to a predetermined input;

prediction means for predicting a combination of keys, according to said detected state of keys by said detecting means and said stored combination of keys in said memory means; and

input control means for controlling keys, so that an operation for a key, which is not included in said predicted combination by said prediction means, is invalid.

14. The information processing apparatus according to claim 13, further comprising

display means for displaying said predicted combination by said prediction means.

15. The information processing apparatus according to claim 13, wherein

said prediction means predicts a combination of keys, when said detecting means detects a change in the state of keys.

16. The information processing apparatus according to claim 14, further comprising

highlight display means for displaying a key included in said predicted combination by said prediction means, so as to have a different feature from a key, which is not included in said predicted combination.

17. An input method of performing an input by a plurality of keys operated simultaneously, comprising:

detecting a state of keys;

storing a combination of keys operated simultaneously, which corresponds to a predetermined input;

predicting a combination of keys, according to said detected state of keys and said stored combination of keys; and

controlling keys, so that an operation for a key, which is not included in said predicted combination, is invalid.

18. The input method according to claim 17, further comprising:

displaying said predicted combination.

19. The input method according to claim 17, further comprising:

when a change in the state of keys is detected, predicting a combination of keys.

20. The input method according to claim 18, wherein

a key included in said predicted combination of keys is displayed, so that the key has a different feature from a key, which is not included in said predicted combination.

21. A computer program for performing an input by a plurality of keys operated simultaneously, the computer program causing a control unit of a computer to execute:

a detection process for detecting a state of keys;

a memory process for storing a combination of keys operated simultaneously, which corresponds to a predetermined input;

a prediction process for predicting a combination of keys, according to said detected state of keys and said stored combination of keys; and

an input control process for controlling keys, so that an operation for a key, which is not included in said predicted combination, is invalid.

22. A recording medium, in which a program which makes a computer execute processing to perform input by a plurality of keys operated simultaneously, the processing comprising:

a detection process for detecting a state of keys;

a memory process for storing a combination of keys operated simultaneously, which corresponds to a predetermined input;

a prediction process for predicting a combination of keys, according to said detected state of keys and said stored combination of keys; and

an input control process for controlling keys, so that an operation for a key, which is not included in said predicted combination, is invalid.

23. An input device for performing an input by a plurality of keys operated simultaneously, comprising:

a detecting unit that detects a state of keys;

a memory unit that stores a combination of keys operated simultaneously, which corresponds to a predetermined input;

a prediction unit that predicts a combination of keys, according to said detected state of keys by said detecting unit and said stored combination of keys in said memory unit; and

an input control unit that controls keys, so that an operation for a key, which is not included in said predicted combination by said prediction unit, is invalid.

24. The input device according to claim 23, further comprising

a display unit that displays said predicted combination by said prediction unit.

25. The input device according to claim 23, wherein

said prediction unit predicts a combination of keys, when said detecting unit detects a change in the state of keys.

26. The input device according to claim 24, further comprising

a highlight display unit that displays a key included in said predicted combination by said prediction unit, so as to have a different feature from a key, which is not included in said predicted combination.
