Refreshable tactile displays offer a tactile alternative for users with visual impairments to access graphical information. However, their low resolution and uniform texture makes the integration of touch-triggered auditory feedback a potentially useful feature. In this work, we explore the design of such feature through co-design work on user requirements for a refreshable tactile display, using a hybrid prototype made of paper overlays in combination with an iPad app. This prototype has been used in a workshop at a school with blind youths in Germany, and we present preliminary results and recommendations.

摘要

Refreshable tactile displays offer a tactile alternative for users with visual impairments to access graphical information. However, their low resolution and uniform texture makes the integration of touch-triggered auditory feedback a potentially useful feature. In this work, we explore the design of such feature through co-design work on user requirements for a refreshable tactile display, using a hybrid prototype made of paper overlays in combination with an iPad app. This prototype has been used in a workshop at a school with blind youths in Germany, and we present preliminary results and recommendations.
