Abstract

A display apparatus for displaying handwriting data, the display includes a handwriting recognition controller configured to control recognition of the handwriting data that is handwriting based on a position of an inputter in contact with a display; a display controller configured to display, on the display, validated data obtained by converting the handwriting data; and a character string insertion controller configured to insert a character string candidate among characters forming the validated data upon determining that the handwriting data that is handwritten around the validated data satisfies a predetermined condition with respect to the validated data, the character string candidate being obtained by converting the handwriting data, which is handwritten around the validated data. The display controller displays an insertion character string candidate in which the character string candidate, which is obtained by the converting, is inserted among the characters forming the validated data.

First claim

What is claimed is:

1. A display apparatus for displaying handwriting data, the display apparatus comprising:
a processor; and
a memory storing programs causing the processor to:
recognize handwriting data that is handwriting based on a position of an inputter in contact with a display;
display, on the display, validated data obtained by converting the recognized handwriting data; and
insert, a character string candidate among characters forming the validated data upon determining that the handwriting data that is handwritten around the validated data satisfies a predetermined condition with respect to the validated data, the character string candidate being obtained by converting the handwriting data, which is handwritten around the validated data; and
upon determining that the predetermined condition is satisfied, displaying, in a selectable manner, (i) the character string candidate obtained by converting the handwriting data handwritten around the validated data, and (ii) an insertion character string candidate in which the character string candidate, which is obtained by the converting, has been inserted among the characters forming the validated data.

2. The display apparatus according to claim 1 , the programs causing the processor to:
upon determining that a selection of the insertion character string candidate is accepted by the inputter,
erase the validated data and the handwriting data, and display the insertion character string candidate at a position where the validated data had been displayed.

3. The display apparatus according to claim 1 , the programs causing the processor to:
upon determining that a selection of the character string candidate is accepted by the inputter,
not erase the validated data but erase the handwriting data, and display the character string candidate at a position where the handwriting data had been displayed.

4. The display apparatus according to claim 1 , wherein
the predetermined condition includes a condition that a distance between the validated data and the handwriting data that is handwritten around the validated data, is less than or equal to or less than a predetermined threshold value, and the programs causing the processor to:
upon determining that the predetermined condition is satisfied,
generate the insertion character string candidate by inserting the character string candidate, which is obtained by converting the handwriting data handwritten around the validated data in between two characters forming the validated data that are closest to an initial character in the handwriting data, among the characters forming the validated data.

5. The display apparatus according to claim 4 , wherein
the predetermined condition includes another condition that an insertion symbol defined in advance is included in the handwriting data that is handwritten around the validated data, and the programs causing the processor to:
upon determining that the predetermined condition is satisfied,
generate the insertion character string candidate by inserting the character string candidate, which is obtained by converting the handwriting data handwritten around the validated data, excluding the insertion symbol, in between two characters forming the validated data that are closest to the insertion symbol, among the characters forming the validated data.

6. The display apparatus according to claim 5 , the programs causing the processor to:
display
the character string candidate obtained by converting the handwriting data, which is handwritten around the validated data, and
the insertion character string candidate in which the character string candidate, which is obtained by the converting, has been inserted among the characters forming the validated data, and

upon determining that a selection of the insertion character string candidate is accepted by the inputter,
erase the validated data and the handwriting data including the insertion symbol, and display the insertion character string candidate at a position where the validated data had been displayed.

7. The display apparatus according to claim 6 , the programs causing the processor to:
upon determining that a selection of the character string candidate is accepted by the inputter,
not erase the validated data and does not erase the insertion symbol but erase the handwriting data that does not include the insertion symbol, and displays the character string candidate at a position where the handwriting data had been displayed.

8. A non-transitory computer-readable recording medium storing a program that causes a computer to execute a process performed in the display apparatus for displaying handwriting data, the process comprising:
controlling recognition of the handwriting data that is handwriting based on a position of an inputter in contact with a display;
displaying, on the display, validated data obtained by converting the handwriting data; and
inserting a character string candidate among characters forming the validated data upon determining that the handwriting data that is handwritten around the validated data satisfies a predetermined condition with respect to the validated data, the character string candidate being obtained by converting the handwriting data, which is handwritten around the validated data; and
upon determining that the predetermined condition is satisfied, displaying, in a selectable manner, (i) the character string candidate obtained by converting the handwriting data handwritten around the validated data, and (ii) an insertion character string candidate in which the character string candidate, which is obtained by the converting, has been inserted among the characters forming the validated data.

9. A display method performed by the display apparatus for displaying handwriting data, the display method comprising:
controlling recognition of the handwriting data that is handwriting based on a position of an inputter in contact with a display;
displaying, on the display, validated data obtained by converting the handwriting data; and
inserting a character string, candidate among characters forming the validated data upon determining that the handwriting data that is handwritten around the validated data satisfies a predetermined condition with respect to the validated data, the character string candidate being obtained by converting the handwriting data, which is handwritten around the validated data; and
upon determining that the predetermined condition is satisfied, displaying, in a selectable manner, (i) the character string candidate obtained by converting the handwriting data handwritten around the validated data, and (ii) an insertion character string candidate in which the character string candidate, which is obtained by the converting, has been inserted among the characters forming the validated data.
