Character string input device and method

Abstract

A character string input method includes inputting a pattern, calculating a pattern evaluation value thereof using a pattern recognition dictionary, outputting a plurality of recognition candidate characters in a pattern evaluation value descending order, selecting an optimal recognition candidate character therefrom using a contextual dictionary, generating search character strings by combining the recognition candidate characters, searching a prediction dictionary using the generated search character strings as keys, outputting a plurality of prediction candidate character strings, and displaying the prediction candidate character strings and the optimal recognition candidate character. In this method, it is judged whether a condition for updating the display so as to display the latest prediction candidate character strings is satisfied, and in the case where it is judged that the foregoing condition is satisfied, the display is updated so as to display the latest prediction candidate character strings. Thus, the character string input device and method is provided in which the user is allowed to select a prediction candidate character string at a certain desired timing by controlling a timing for updating the display of a result of a predicting operation.

Description

technical field [0001] The present invention generally relates to a character string input device and method, and more particularly to a character string input device and method in which character string prediction is performed based on recognition of handwritten character patterns and conversion of the patterns into character strings. Background technique [0002] With the rapid development of computer technology in these years, especially the improvement of recognition accuracy and processing speed in the technical field of pattern recognition (Pattern recognition), there are various applications for inputting handwritten characters. [0003] More specifically, in a technique of recognizing a handwritten character pattern input through an input medium such as a pen-controlled tablet and converting the pattern into an appropriate character string, a technique has been developed in which After a single figure of the handwritten character pattern is recognized, a search chara...

Problems solved by technology

Also in this case, if the user suspends the input of handwritten character graphics when a certain character is partially written, and the user selects one of the predicted candidate character strings currently displayed, since when the detected input interval time exceeds The predictive operation is automatically started when the preset input interval time, there is a possibility of the same problem described above
