The goal of the GT Accessible Aquarium Project is to make dynamic exhibits such as those at museums, science centers, zoos and aquaria more engaging and accessible for visitors with vision impairments by providing real-time interpretations of the exhibits using innovative tracking, music, narrations, and adaptive sonification.

In this project, they are developing cutting edge bio-tracking and behavior analysis techniques that can provide input for sophisticated, informative, and compelling multimedia auditory displays, music, and sonifications (sounds used to convey information about some kind of data to a listener). They are focusing first on the aquarium domain, since almost every exhibit in an aquarium is dynamic.

Here is a link to the Georgia Tech Center for Music Technology describing the project:
