Despite its importance in our lives, technology is still frequently frustrating, dehumanising, or just plain boring. So while our everyday life is saturated with technology, our relationship to it is still very far from perfect. In the Internet of Things era, we will be surrounded by even more technology. What could a stronger focus on enjoyment, creativity and engagement – for all – bring? I will present some of the tactics, methods and insights gained from the work in the Mobile Life centre. We frame our work as doing serious research on what we might normally portray as “unserious” activities. Our work is interdisciplinary, design-led, based on detailed ethnographic studies, often in collaboration with experts in a varied set of fields – such as fashion studies, fine art, opera, medical science, street performance, TV-production or somaesthetic practices. We get inspired by doing studies on people’s mundane leisure and creative activities such as horseback riding, hunting, parkour, dancing or live-action role-playing. We use those insights to spur innovative design processes, resulting in mobile applications, sensor-based applications, pervasive games, new mobile media, technical platforms and materials to support amateurs’ creativity. In this talk, I will give an overview of some of the research done, focusing in particular on how we see Internet of Things as a design material, ways of exploring aesthetics, the role of the materials in our design processes and how to articulate design knowledge.
