Once they chose a point to investigate, they start walking in that direction. Here the participant chose to explore a restaurant on 7th Street that is now occupied by the Park and Shop. Once she arrives, she can interact with the location in a number of different ways. She can see a drawing overlay that shows what the building looked like in 1921. Choose to either listen to audio narration or read about the location. Look at photographs or listen to related sound artifacts. All of these options are designed to let the participant uncover the past themselves, which is what my research showed was most valuable.
