As part of the U.K. Equator IRC, a multidisciplinary group of researchers have collaborated in the design of digitally augmented environments with the intention of addressing the question of how such augmentation supports learning about, and interaction with, the environment. A number of innovative play and learning environments have been developed to explore ways in which ubiquitous technologies can support effective, imaginative and engaging interaction for children. These scenarios range from indoor settings to field trips into the countryside. They involved both audio and visual media used with innovative devices, each presenting particular challenges and design opportunities. In this paper we first briefly describe our experiences in the yAmbient Woody, then discuss a related framework which has been applied to the further development of this work, and finally discuss itys relevance to the concepts of yUbiPhysicsy.
