We’ve been putting together an interactive media strategy for a history museum, and one of the ideas has been to create a series of points in the visit that use sensors and large projections to amplify the “you are there” experience – a visitor triggers a cued moment in a video so it seems as if someone is gesturing at or talking to him. The concept has brought up interesting issues about visitor choreography: How can we ensure that everyone gets the experience? It doesn’t seem possible? If not, does it really matter? We’ll keep thinking it through.
