Abstract

Text input is corrected on a touch-sensitive display by presenting a list of candidate words in the interface which can be selected by touch input. The candidate list can include candidate words having two or more character types (e.g., Roman, kana, kanji). In one aspect, the candidate list can be scrolled using a finger gesture. When a user'"'"'s finger traverses a candidate word and the touch is released, the candidate word is inserted into a document being edited. In another aspect, characters can be erased by touching a key (e.g., a backspace or delete key) and making a sliding, swiping, or other finger gesture. A number of characters proportional to a distance (e.g., a linear distance) of the finger gesture across the display are erased. If there are characters in a text input area, those characters are erased first, followed by characters in the document being edited.

Claims

1. A method comprising:

at a device with a touch-sensitive display;

receiving text input for a document being edited on the touch-sensitive display;

determining if the text input includes an incorrect character or if the text input is ambiguous;

upon determining that the text input includes an incorrect character or that the text input is ambiguous, determining a list of possibly correct candidate words;

displaying the list of candidate words on the touch-sensitive display, wherein each respective candidate word is displayed at a respective original position;

detecting a finger touching or traversing one or more candidate words in the list of candidate words;

in response to detecting the finger touching or traversing a respective candidate word, simultaneously displaying the respective candidate word at a position on the touch-sensitive display that is offset from the respective original position where the respective candidate word is displayed in the list of candidate words and displaying the respective candidate word at the original position within the list of candidate words;

receiving touch input selecting one of the candidate words; and

inserting the selected candidate word into the document being edited.

2. The method of claim 1, where at least some of the text input is in Japanese.

3. The method of claim 1, where the list of candidate words includes candidate words having characters in two or more character types.

4. The method of claim 1, where the list of candidate words is determined based on one or more of a user-selected language or statistics.

5. The method of claim 1, where the list of candidate words is determined using an auto-correcting search, which accounts for possible typographical errors in the text input.

6. A non-transitory computer-readable storage medium having instructions stored thereon, which, when executed by a device with a touch-sensitive display and a processor, cause the processor to perform operations comprising:

receiving text input for a document being edited on the touch-sensitive display;

determining if the text input includes an incorrect character or if the text input is ambiguous;

upon determining that the text input includes an incorrect character or that the text input is ambiguous, determining a list of possibly correct candidate words;

displaying the list of candidate words on the touch-sensitive display, wherein each respective candidate word is displayed at a respective original position;

detecting a finger touching or traversing one or more candidate words in the list of candidate words;

in response to detecting the finger touching or traversing a respective candidate word, simultaneously displaying the respective candidate word at a position on the touch-sensitive display that is offset from the respective original position where the respective candidate word is displayed in the list of candidate words and displaying the respective candidate word at the original position within the list of candidate words;

receiving touch input selecting one of the candidate words; and

inserting the selected candidate word into the document being edited.

12. The medium of claim 6, where at least some of the text input is in Japanese.

13. The medium of claim 6, where the list of candidate words includes candidate words having characters in two or more character types.

14. The medium of claim 6, where the list of candidate words is determined based on one or more of a user-selected language or statistics.

15. The medium of claim 6, where the list of candidate words is determined using an auto-correcting search, which accounts for possible typographical errors in the text input.

7. A system comprising:

a touch sensitive-display;

a processor; and

memory coupled to the processor and storing instructions, which, when executed by the processor, cause the processor to perform operations comprising;

receiving text input for a document being edited on the touch-sensitive display;

determining if the text input includes an incorrect character or if the text input is ambiguous;

upon determining that the text input includes an incorrect character or that the text input is ambiguous, determining a list of possibly correct candidate words;

displaying the list of candidate words on the touch-sensitive display, wherein each respective candidate word is displayed at a respective original position;

detecting a finger touching or traversing one or more candidate words in the list of candidate words;

in response to detecting the finger touching or traversing a respective candidate word, simultaneously displaying the respective candidate word at a position on the touch-sensitive display that is offset from the respective original position where the respective candidate word is displayed in the list of candidate words and displaying the respective candidate word at the original position within the list of candidate words;

receiving touch input selecting one of the candidate words; and

inserting the selected candidate word into the document being edited.

8. The system of claim 7, where at least some of the text input is in Japanese.

9. The system of claim 7, where the list of candidate words includes candidate words having characters in two or more character types.

10. The system of claim 7, where the list of candidate words is determined based on one or more of a user-selected language or statistics.

11. The system of claim 7, where the list of candidate words is determined using an auto-correcting search, which accounts for possible typographical errors in the text input.
