JPH02282883A - Recognizing system for handwriting input - Google Patents

Abstract

PURPOSE:To enable even an unskilled operator to fast input the instructed data and to improve the accuracy of recognition by preparing a reference pattern including plural segments which turn the characters to be inputted into the fixed forms and inputting characters after deciding a character pattern with use of those segments. CONSTITUTION:A reference pattern 100 includes grooves 1 - 28, and a character pattern is turned into a fixed form with combinations of grooves 1 - 28. An operator applies the characters to the pattern of a fixed form and traces the grooves in order to input these characters. In other words, the input characters can be recognized with combinations of grooves traced by the operator. As a result, even the operator can input the designated data in the same way as writing characters and with high accuracy.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a handwritten input recognition method.

[1) ``Current technology'' Generally, when an operator inputs data into a computer, a similar method is used.

(1) Keyboard input.

A method by pressing a key that corresponds to a single letter/symbol.

(2) A method of reading character patterns handwritten within a certain frame on character reading paper, etc.

[Problem to be solved by the invention]

Among the conventional methods described above, <1) has the disadvantage that it takes a very long time to input instruction data until the operator gets used to the keyboard, and the operating efficiency is very poor. Also (2)
Although input can be performed relatively quickly even by an inexperienced operator, the disadvantage is that there is a large degree of freedom in handwriting, and character patterns are often difficult to read or misrecognized.

SUMMARY OF THE INVENTION An object of the present invention is to provide a system that allows even an inexperienced operator to input instruction data quickly and to improve recognition accuracy.

[Means to solve the problem]

The handwritten input recognition method of the present invention has a reference pattern including a plurality of line segments that regularizes characters to be input, and uses the line segments to determine a character pattern, and when inputting the characters. This is realized by detecting the character pattern and recognizing the character.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram showing a reference pattern 100. In the figure, the reference pattern 100 has lines 1 to 28. The character pattern is defined by a combination of grooves 1-28.

FIG. 2 is an explanatory diagram showing an example of a character pattern in which kana characters are standardized using the above-mentioned characters 1 to 28 as elements. The operator can input characters by matching them to a standardized pattern and crossing them out. In other words, input characters are recognized by the combination of grooves traced by the operator.

〔Effect of the invention〕

As described above, according to the present invention, even an inexperienced operator can input instruction data in the same way as when writing characters, and can perform highly accurate input.

It also has the effect of reducing the area occupied by the keyboard.

[Brief explanation of drawings]

FIG. 1 is an explanatory diagram of a reference pattern showing an embodiment of the present invention, and FIG. 2 is an explanatory diagram showing an example of a pattern in which kana characters are standardized. 1 to 28... erase, 100... standard pattern.

Claims (1)

[Claims] It has a reference pattern that includes a plurality of line segments that standardizes the character to be input, the line segments are used to determine the character pattern, and when the character is input, the character pattern is detected and the character is A handwritten input recognition method characterized by recognition.
