The research on Silo has been inspired by perspectives and techniques from interaction design and human-computer interaction, as well as CSCL and mobile learning. We have designed and implemented the authoring tool and a mobile application for location-based games and experiences. The tools have been tested and analyzed in field trials and gone through several iterations of design and evaluation. Our research interest has been particularly concerned with how the technology is actually used in realistic situations and how the technology feature in the interaction of the participants. Video analysis and interaction analysis have been the main perspective and methods in the analytic and empirical work. We have also addressed and given examples of how the technology can be integrated into a school setting through the design and analysis of learning scenarios.
