発明の名称 (英語) PROGRAM, INFORMATION STORAGE MEDIUM, AND RECOGNITION DEVICE
発明の概要(英語) Provided is a recognition device or the like which is capable of recognizing mathematical formulae including character strings. This recognition device includes: a registration unit which determines whether inputted strokes or stroke strings correspond to a specific gesture for demarcating a character string and a mathematical formula, and, in cases when the inputted strokes or stroke strings are determined to correspond to the specific gesture, registers information related to the range specified by the specific gesture; a demarcation unit which sets, as strokes corresponding to the character string, the strokes included in the range specified by the specific gesture among the inputted strokes, and sets, as strokes corresponding to the mathematical formula, the strokes not included in the range specified by the specific gesture; and a recognition unit which uses a character-string-recognition engine to recognize the character string from the strokes set as the strokes corresponding to the character string, and uses a mathematical-formula-recognition engine to recognize the mathematical formula from the stokes set as the strokes corresponding to the mathematical formula.
従来技術、競合技術の概要(英語) BACKGROUND ART
Conventional, the input expression as a method, a method using a specialized language such as LaTeX, a method of using an editor can be used as the input expression has been, it is necessary to learn the terminology is the former, the latter need to be repeated and the symbol selection and menu selection, user-friendly to the public are poor. On the other hand, the computer handwriting tablet or the like recognized by the equation a method has been studied from old. Then, the research for many years by the recognition rate is improved and, further, in recent years the rapid spread of a tablet-type PC, can permeate the public are also increasing.
