I have been going back and forth between what the physical experience will be.. My initial idea was to blindfold a person and have something guide them around the room, either using an Arduino or else have someone give instructions through a phone call, walkie talkie etc. Then the idea changed to using binaural microphones which record sound with the intent of creating a 3D experience. So I would go out and record the sound of me walking down a street, at the same time I would be recording a video of it too. I will then overlay different sound effects and directions like a visually impaired user would experience using the app. In the exhibition a visitor will be asked to put on a pair of earphones to listen to the sound and watch the video to get a sense of what the visually impaired user would feel when using the app and navigation system.
