Aided Exploration of Virtual Contents by Blind People

F. RennaF. De FeliceG. AttolicoA. Distante

This paper describes the main features of a multimodal application, based on haptic/acoustic interaction, that allows visually impaired people to access 3D virtual contents. We have realized a few applications addressing specific contexts, from the exploration of 3D spatial data to the fruition of cultural heritage.Several test sessions, involving users with different stories and different level of visual disability, have been accomplished. They have shown that the haptic/acoustic interaction supported by the definition of multimodal interactive objects, the progressive access to information and guided paths through the models are a powerful tool for blind people to catch information and to enhance their knowledge of the real world
