Abstract

This paper introduces a multimodal interactive system which aims to enable blind and visually impaired persons to create, manipulate and explore graph structures in a 3D space. An audio-haptic interaction paradigm has been designed to ensure a non-visual experience of graph structures. Visual feedback makes possible communication about graphs between non-sighted and sighted users. The multimodal manipulation and exploration techniques are introduced together with the system prototype. Early evaluation results are illustrated.
