Abstract

Quick prototyping of tangible user interfaces is currently hampered by availability of toolkits and the double challenge of tinkering with software and hardware. While software may be downloaded, hardware cannot. As a work-around for a class on experimental prototyping of tangible appliances we utilized the ARToolKit that tracks optical markers. By creatively adapting it, our students quickly developed working prototypes, simulating a range of devices and tracking technologies. Our approach enabled a focus on quick prototyping, idea testing and simulation of the interaction process. We explain our reasons for using the ARToolKit, summarize its advantages and disadvantages, present four students projects, and discuss our experiences and conclusions. In particular we found that visual tracking has the advantage not to limit or determine possible interaction styles and thus fosters designing richer interaction. We discuss this as a requirement for future tangible prototyping toolkits.
