Learning in Mixed Realities (Mixed Reality Learning) combines Situated Learning and eLearning. It uses a well-balanced mixture of learning in the physical context and computer-supported learning with contextualized information access. A physical environment and the physical objects contained within the learning environment are tightly connected to digital information and computer-controlled learning procedures. The digitally enriched physical space for the activities is designed as an Ambient Environment where embedded, mostly invisible computers provide hardware- and software-based functionality attached to the room and its objects. Objects in the environment are designed as Tangible Objects with intertwined physical and digital properties. As a result, the learner encounters a natural learning context enhanced by eLearning functionality. The strength of Situated Learning is combined with the strength of Computer-Based Instruction....
