We present our approach to the design of two generations of outdoors device that enable visitors to view 3D historical reconstructions when exploring present day sites. Reacting to problems revealed through public trials with our first prototype, we describe how we followed a ‘physical form inwards’ approach for the design of our second prototype – Augurscope II. We began by refining the physical form of the interface through a series of push tests with low-tech wooden prototypes and subsequently added sensors and finally refined the software. Our experience with the Augurscope II highlights the importance of prototyping, early involvement of users within the intended setting and the subtleties involved in matching physical form, sensors and software in the development of ubicomp devices.
