This hands-on workshop will demonstrate the ongoing research to practice development of a US National Park Service (NPS) grant on providing audio described NPS brochures through mobile technology. Currently, the NPS is expanding the accessibility of informational materials for park users with a focus on end-user’s with mobile technology, such as Smartphones and tablets, and a text-to-speech application for blind and visually-impaired users. The workshop will feature a hands on demonstration of the beta versions of both the front end application, which participants can upload to their mobile device, and the back end application where onsite Park Service personnel upload the information for export to the mobile app. The workshop will also include a discussion of best practices for the audio description of print material such as brochures and maps.
