Designing Haptic Computer Interfaces for Blind People

Calle Sjöström, Certec, Department of Design Sciences, Lund University, SWEDEN

Presented at ISSPA 2001, Kuala Lumpur, Malaysia,  August 13 - 16, 2001


Abstract

Certec has been working on touch interfaces – haptic interfaces – since 1995, exploring the possibilities they can offer people with different kinds of disabilities. With a haptic computer interface a blind person can learn mathematics by tracing touchable mathematical curves, playing haptic computer games, and gaining better access to graphical user interfaces like Windows.

This paper presents a brief overview of a set of tests that have been made and some of the results from these tests.

This is followed by a set of design recommendations that we have been able to extract as an extended result of this research and development work. These guidelines are grouped under the headings Navigation, Finding objects, Understanding objects, Haptic widgets and Physical interaction.
