The future of signs: interactive information, inexpensively!

We present an inexpensive, interactive ubiquitous computing system that supports information presentation on demand using a novel "card reading" interaction style. We've deployed this system in our office as a means of supporting wayfinding, sales presentations, project context sharing, and notification (e.g., is there any free food in the kitchen?). However, since the system is essentially an information appliance embedded in our physical space, it also enables people to navigate through our information space-a much more challenging and exciting.
