A methodology for developing and evaluating the usability of audio-based virtual environments for learning and cognition of blind people

Abstract

During the last decade, a pioneering work on sound-based virtual environments for developing cognition and learning in blind users has been developed. This article describes this innovative work in detail, namely qualitative and quantitative research about learning and cognition using 3D sound interactive virtual environments and cognitive tasks with blind users. Research demonstrates the benefit of a sound-based virtual environment and specific cognitive tasks for the learning and cognition in blind children. Spatial sound can help to improve and rehearse memory, haptic perception, tempo-spatial cognitive structures, mobility and orientation, mathematics and science learning, and problem solving. A relevant and critical result of this research has been the transfer of virtual learning to real life learning situations. All of this has lead us to confirm the hypothesis that sound-based virtual environments can be used to construct meaning and develop the intellect of blind users.
