Purpose of the research study: The biggest barrier to the independence of the visually impaired is often the problem of mobility. Mobility training is difficult and intimidating.

The project uses publicly available 3D models of buildings, towns and cities to automatically generate audio-based “maps” for the blind. The visually impaired can then use these “maps” to explore environments virtually. These “maps” use 3D audio and text-to-speech to convey information to the user.  With this software, users become accustomed to the layout of the environment and memorize routes they can use in real-world navigation. While this technology is most beneficial to the visually impaired, this study is also open to sighted individuals.
These maps can offer varying level of detail; the purpose of this study is to discover whether or not more detailed audio information leads to better recall of layouts and routing.

What you will do in the study: Using an Android tablet and headphones, you will explore a 3D audio environment for a limited amount of time. To encourage focus, you will be blindfolded while exploring. After a tutorial, you will be expected to explore independently. When the time limit has passed, you will be asked a series of questions about the environment you explored.

Time required: One to two hours continuously.
