Here’s the presentation we gave (31MB) on our participatory design work for the BlueWay sign system. The project context has changed to the ITP Spring Show. We interviewed potential users about what they might expect from such a system, had them perform a card-sorting task to organize information about the show, and asked them to draw how they felt that information would be displayed. It was a very revealing exercise which guided us toward focusing on presence. Social information ranks very highly with humans, so our user’s interest in seeing who is around them makes a lot of sense.
