Teaching Data Structures to Students who are Blind

By Calder, Matt; Cohen, Robert F.; Lanzoni, Jessica; Landry, Neal; Skaff, Joelle; ITiCSE ’07 - Proceedings of the 12th Annual SIGCSE Conference on Innovation and Technology in Computer Science Education,
Publication Date: 2007

Paper presents a software system designed to help students who are blind understand fundamental algorithms and data structures. The PLUMB EXTRA3 (Exploring data sTRuctures using Audible Algorithm Animation) conveys an algorithm animation using audio cues and synthesized speech. The user can incrementally move forward and backward through the steps of an algorithm. The system used synthesized speech to speak a brief description of each step. At each step of the algorithm, the user can explore the state of the data structure to understand the changes. In this way, they can gain an understanding of the behavior of the algorithm.
