Abstract

A system for inputting information by utilizing an extension key. The system includes: an input unit having multiple division areas and detecting a division area selected by a user from among the multiple division areas; and an input analysis unit for allocating corresponding information to the multiple division areas and analyzing that if the input unit detects any of the multiple division areas being selected, information allocated to the selected division area is input, wherein multiple characters are allocated to each of the multiple division areas, when one or more of the division areas are selected, predicted words that are generated by combining characters allocated to the selected division area or areas according to an sequential order of the selected division area or areas are extracted and allocated to each of the division areas, and when a division area to which the predicted word is applied is selected by a predetermined method, the input analysis unit analyzes that the predicted word allocated to the division area which has been selected by the predetermined method is input.

Claims

1. A system for inputting information by utilizing an extension key, the system comprising:

an input unit having multiple division areas and detecting a division area selected by a user from among the multiple division areas; and

an input analysis unit for allocating corresponding information to the multiple division areas and analyzing that if the input unit detects any of the multiple division areas being selected, information allocated to the selected division area is input,

wherein multiple characters are allocated to each of the multiple division areas,

when one or more of the division areas are selected, predicted words that are generated by combining characters allocated to the selected division area or areas according to an sequential order of the selected division area or areas are extracted and allocated to each of the division areas, and

when a division area to which the predicted word is applied is selected by a predetermined method, the input analysis unit analyzes that the predicted word allocated to the division area which has been selected by the predetermined method is input.

2. The system of claim 1, wherein an extension key is allocated to at least one of the multiple division areas,

when the extension key is selected after one or more of the division areas are selected, the predicted words that are extracted are allocated to an extension area including the division areas adjacent to the division area to which the extension key is allocated, and

when a division area is selected after the allocation of the predicted words to the division areas in the extension area, the input analysis unit analyzes that the predicted word allocated to the division area is input.

3. The system of claim 1, wherein

the input unit comprises a touch sensor to determine the user'"'"'s touch, and

the input analysis unit analyses that the predicted word allocated to the division area is input if the user touches the division area to which the predicted word is allocated, and performs a dragging operation a predetermined distance or greater.

4. The system of claim 1, wherein

an extension key is allocated to at least one of the multiple division areas, and

if one or more of the division areas are selected, then the extension key is selected, which allocates predicted words to the division areas, and one of the division areas is selected, the input analysis unit analyses that the predicted word allocated to the division area is input along with a space input after the predicted word.

5. The system of claim 2 or claim 4, wherein

the input unit comprises a touch sensor which can determine the user'"'"'s touch, and

selection of the extension key and selection of the division area which are performed after selecting one or more of the division areas from among the multiple division areas in order to extract the predicted words are made as one dragging operation.

6. The system of claim 5, wherein in a state where no division area is selected from among the division areas and no predicted word has been allocated to the division area, a dragging operation which corresponds to the selection of the extension key and the selection of the division area acts as if a shift key is pressed so that the character set corresponding to the selected division area may be input in capital form instead of inputting the predicted word.

7. The system of claim 2, wherein if after one or more of the division areas are selected, the extension key, a division area included in the extension area, and the extension key are selected sequentially, the predicted word that has been allocated to the selected division area is input with a space input after the predicted word.

8. The system of claim 7, wherein

the input unit comprises a touch sensor to determine the user'"'"'s touch, and

after one or more of the division areas are selected and the predicted words are allocated to the extension area, a series of selection processes including the selection of the extension key, the selection of the division area, and the selection of the extension key is to be performed by one dragging operation.

9. The system of claim 2, wherein after one or more of the division areas are selected, the predicted words are allocated to the extension area, and a series of selection processes including the selection of the extension key, the selection of a division area included in the extension area, and the selection of the extension key is performed, the predicted word which is allocated to the selected division area is input and then symbols are newly allocated to the extension area to be selected.

10. The system of claim 9, wherein

the input unit comprises a touch sensor so as to determined the user'"'"'s touch, and

a series of selecting processes including the selection of the extension key, the selection of a division area, and the selection of the extension key is performed by one dragging operation.

11. The system of claim 1, wherein

the input unit comprises a touch sensor so as to determine the user'"'"'s touch, and

the input analysis unit allocates the extension key to at least one division area from among the multiple division areas so that the following cases perform different functions

(1) a dragging operation of selecting the division area and selecting the extension key;

(2) a dragging operation of selecting the division area, selecting the extension key, and selecting the division area included in the extension area;

(3) a dragging operation of selecting the extension key and selecting the division area; and

(4) a dragging operation of selecting the extension key, selecting the division area, and selecting the extension key.

12. The system of claim 2, wherein a method of selecting the characters allocated to the division area and a method of selecting the predicted word allocated to the division area are distinguished from each other, and when selecting the characters allocated to the division area, characters are allocated to the extension key, too.
