This project is a model tour in the Kentucky State Park system in honor of the 150th anniversary celebration of the Civil War. The Perryville Battlefield State Historic Site and the Friends of the Battle of Perryville worked with Ball State University students to create a phone application using GPS (Global Positioning System) software that helps visitors to the state parks learn about the history of the park through a combination walking and driving tour. They see the park in person, but experience enhancement elements /interpretative materials through the app on their phone including maps and video.
