This dissertation describes an interaction design project which investigates whether the symbiosis of physical and digital environments might be used to create a stronger sense of ‘place’ for the occupants of the physical space. Sensing technology, implicit interaction, ambient interfaces, game strategy and a network connection were combined in an attempt to increase participants' awareness of their physical actions and location. The principles and theory underpinning this project are discussed, after which a list of criteria for an interactive system designed for public spaces is drawn up. The design of SuperFight I is described and evaluated in relation to this theoretical background. Finally suggestions are made for future areas of research that might be undertaken in order to develop the system further
