Science Learning in Blind Children through Audio-Based Games

In this study we present AudioLink, an interactive audio-based virtual environment for children with visual disabilities to support their learning of science. AudioLink is a Role-Playing Game (RPG) for learning science concepts and scientific reasoning through audio. We analyzed how blind learners can learn science using audio as the main input/output interface and how to develop a challenging and engaging software. The usability of this software and a preliminary study of the cognitive impact were also evaluated. Results indicated that users considered the software was appealing, challenging and encouraging as a science learning tool. AudioLink promoted a free and independent interaction at the users’ own paces. Evidence indicates that blind children developed scientific thinking skills to identify a problem, build a strategy to solve it, and understand when it was solved.
