Analysis of implicit didactics in math schoolbooks for interactive non-visual user interface development

Abstract

Most math schoolbooks consist of practical and theoretical parts where the theoretical parts guide the students and explain the strategies on how to solve a given problem. These theoretical parts contain visual didactic information where the problem solving processes are explained using pictorial and spatial representations. So far, there is no workaround for non-visual user interfaces such as refreshable braille displays to represent this implicit visual information. This affects learning ability of visually impaired and blind students. In this paper, we present the results from analyzing these implicit notations and the possible strategies to help visually impaired and blind students benefiting from visual didactic information in math schoolbooks.
