A pattern recognition method of mathematical graphs

Abstract: A computer-aided system for transformation of mathematical figures into tactile graphics is useful for visually impaired students when they learn mathematics and science.To develop such a system, research on mathematical figure recoguition techniques is needed. It is natural to assume that (1) mathematical figures include characters and formulas to explain lines or curves that are graphical expressions of functions or equations, and (2) graphs are sometimes drawn using broken lines. Under these assumptions, th… Show more

“…Finally, it is interesting to compare the touching model with some material models such as a tactile graph [2] and a graph made by wire. As far as planar graphs are concerned, both models can represent any graph as it is.…”

“…For example, several types of software that can convert selected visual information into text form and then convey the data as synthesized speech or Braille, are already commercially available. Tactile graphics or pictures can be understood more easily by visually impaired persons, but it is sometimes difficult for visually impaired students to recognize mathematical figures correctly when using tactile devices [3]. The primary issue is that congenitally visually impaired persons (defined as persons who are born without sight or who lose it soon after birth) are unable to benefit from visual experiences or imagery.…”
