Abstract

To provide the input device in the present invention, which allows comfortable operation with lightened mental and physical load, has at least one input key and includes: an association storage unit storing an array of plural information in association with the input key, the plural information each having an order; a selection unit selecting, from the array, predetermined information as input information; a touch detection unit detecting that an object touches a surface of the input key; and a movement relevant information detection unit detecting movement relevant information concerning a movement of a contact point between the surface of the input key and the object, the contact point being detected by the touch detection unit. The selection unit selects, from the array, information having a predetermined order stored in association with the input key on which the touch detection unit detects the touch by the object, based on the movement relevant information.

Claims

1. An input device having at least one input key, comprising:

an association storage unit operable to store an array of plural information in association with said input key, the plural information each having an order;

a selection unit operable to select, from the array, predetermined information as input information;

a touch detection unit operable to detect that an object touches a surface of said input key; and

a movement relevant information detection unit operable to detect movement relevant information concerning a movement of a contact point between the surface of said input key and the object, the contact point being detected by said touch detection unit,

wherein said selection unit is operable to select, from the array, information having a predetermined order stored in association with said input key on which said touch detection unit detects the touch by the object, based on the movement relevant information.

2. The input device according to claim 1,

wherein said input key is a push-type input key, and

said input device further comprises:

a press detection unit operable to detect that said input key is pressed; and

a determination unit operable to determine, as the input information, the predetermined information selected by said selection unit, when said press detection unit detects the press.

3. The input device according to claim 1,

wherein said movement relevant information detection unit is a movement detection unit which is operable to detect that the object touching the surface of said input key moves on the surface of said input key, and

said selection unit is operable to select other information which is present in the array where the predetermined information is present and which is different from the predetermined information selected by said selection unit, in the case where said movement detection unit detects the movement.

4. The input device according to claim 1,

wherein said movement relevant information detection unit is a movement direction detection unit which is operable to detect a movement direction of the object that moves on the surface of said input key, the object touching the surface of said input key, and

said selection unit is operable to select information having an order subsequent to an order of the predetermined information selected by said selection unit, in the case where the movement direction detected by said movement direction detection unit is a first movement direction, or to select information having an order antecedent to an order of the predetermined information, in the case where the movement direction detected by said movement direction detection unit is a second direction.

5. The input device according to claim 1,

wherein said movement relevant information detection unit is a movement speed detection unit operable to detect a movement speed of the object that moves on the surface of said input key, the object touching the surface of said input key, and

said selection unit is operable to select other information which is present in the array where the predetermined information selected by said selection unit is present, the selection being made based on the movement speed detected by said movement speed detection unit, and the other information having an order changed from an order of the predetermined information being a base point for the chance.

6. The input device according to claim 1,

wherein said movement relevant information detection unit is a movement amount detection unit operable to detect a movement amount of the object that moves on the surface of said input key, the object touching the surface of said input key, and

said selection unit is operable to select other information which is present in the array where the predetermined information selected by said selection unit is present, the selection being made based on the movement amount detected by said movement amount detection unit, and the other information having an order changed from an order of the predetermined information being a base point for the change.

7. The input device according to claim 4,

wherein the first movement direction is either upward or rightward, and

the second movement direction is either downward or leftward.

8. The input device according to claim 1,

wherein said selection unit selects:

i) the predetermined information by returning from a last order to a first order in the array, in the case of selecting information subsequent to the last order in the array; and

ii) the predetermined information by returning to the last order in the array, in the case of selecting information antecedent to the information having the first order in the array.

9. The input device according to claim 1,

wherein the information is character-related information indicating at least one of a character, a numeral, and a symbol.

10. The input device according to claim 1,

wherein an array of the character-related information is equivalent to one column of the Japanese syllabary.

11. The input device according to claim 1,

wherein an array of the character-related information is equivalent to the Japanese syllabary.

12. A mobile terminal comprising the input device according to claim 1.

15. A mobile terminal comprising the input device according to claim 2.

16. A mobile terminal comprising the input device according to claim 3.

17. A mobile terminal comprising the input device according to claim 4.

18. A mobile terminal comprising the input device according to claim 5.

19. A mobile terminal comprising the input device according to claim 6.

20. A mobile terminal comprising the input device according to claim 7.

21. A mobile terminal comprising the input device according to claim 8.

22. A mobile terminal comprising the input device according to claim 9.

23. A mobile terminal comprising the input device according to claim 10.

24. A mobile terminal comprising the input device according to claim 11.

13. An input method for an input device having at least one input key, said method comprising the steps of:

detecting whether or not an object touches a surface of said input key;

detecting a movement direction of the object which moves on the surface of said input key, the object touching the surface of said input key; and

selecting, as input information, information having an order subsequent to an order of information selected as input information in an array when it is detected that the object touching the surface of said input key moves on the surface of said input key in a certain direction.

14. A program for an input device having at least one input key, said program causing a computer to execute the steps of:

detecting whether or not an object touches a surface of said input key;

detecting a movement direction of the object which moves on the surface of said input key, the object touching the surface of said input key; and

selecting, as input information, information having an order subsequent to an order of information selected as input information in an array when it is detected that the object touching the surface of said input key moves on the surface of said input key in a certain direction.
