Accessing Tactile Graphics

Evaluating the use of Variable Height in Statistical Tactile Graphics

The creation of effective tactile resources is critical to inclusion of persons with visual impairment and blindness in education. Gaining insight and understanding of tabular data is a highly demanding task for people with visual impairments. Since, tactile perception uses sequential information acquisition rather than the parallel acquisition used by the visual system, it is a challenge for blind students to gather a fast overview of and deeper insight into the data through tactile modality.

Richa is carrying out a research work that focuses on the design of accessible forms of statistical graphics. The aim of such an investigation is to make tactile educational resources more effective and accessible to blind students.  

In this session Richa will talk about the tactile perception of height variation and their effectiveness in the context of statistical tactile diagrams. You will learn about technologies and techniques that can be used in making three dimensional tactile diagrams.
