A TOOL TO SUPPORT DIGITAL LOGIC TEACHING TO BLIND PEOPLE

Abstract

Graphical representation of logical expressions is one essential part of digital circuits learning process. This kind of representation is an obstacle to teachers when it is necessary to teach blind students. The use of screen readers, a type of software that takes information delivered to the screen and redirects it to a synthetic speech, is a way to make the blind people part of the studies in a classroom. However, these softwares are not able to reproduce graphical representation. This paper presents a tool that supports digital logic teaching to blind people using non-visual mechanisms to represent digital circuits and allows non-blind and blind  people to access the same content in different ways.
