Using haptics in computer interfaces for blind people

Abstract

This paper has its roots in Certec's efforts to find a way to use haptic technology (i.e. touch based interfaces) to provide new computer interaction techniques for visually impaired people and those with physical disabilities.The paper presents a set of recommendations that we have formulated during our research and development work. These rules of thumb are grouped under the headlines Navigation, Finding objects, Understanding objects, Haptic widgets and Physical interaction.
