Supporting cross-modal collaboration: adding a social dimension to accessibility

This paper presents a study of cross-modal collaboration, where blind and sighted persons collaboratively solve two different tasks using a prototype that has one auditory and one graphical interface. The results shows the importance of context and the design of tasks for the accessibility of cross-modal collaborative settings, as well as the importance of supporting the participation in a working division of labour.

Designing accessible auditory drag and drop

This paper presents an audio-only version of drag and drop. By continuously presenting the information, using auditory zooming at two different levels and absolute positioning of the cursor, a blind user is able to get an overview, locate and interact with a specific object. Two user studies on two different versions have been made in order to get input to the design process and to evaluate the ideas. The results points at the importance of being able to customize the interface and to provide an overview of all interface objects.
