Help us test a new navigation experience for visiting the EcoTarium. This app is designed to improve the outdoor exhibit experience for all guests, with a special emphasis on increased accessibility for those who are visually-impaired. Developed with a team of students from WPI, this app will help guide visitors around the outdoor exhibit experiences at the EcoTarium. Find your way to the River Otters, Explorer Express, Wild Cat Station, and more! Note, at this time, the app only provides navigation for our outdoor experiences. We're looking for feedback on this app from all visitors. Please email your feedback to protoapp@ecotarium.org, or use the links in the app itself. Please be patient as we gather feedback on the app and work towards developing additional features of the app later this year.
