Watts Down and Flow are the result of design explorations regarding growing IoT systems conducted in the context of the smart home. Together with five other students, I designed three products: 1) a system of localised, tangible adapters designed to create awareness of power usage, 2) a central tangible interface aimed to facilitate discussion and community goal setting around water usage, and 3) a combination of these two devices in one central piece. The design cases as presented had a special focus on rich and embodied interactive systems in order to reflect on possibilities and constraints regarding these subjects. This image shows an overview of all three design explorations as documented in the final report of this course. Our conclusion was the following: “we believe that there is a place for rich interaction in growing systems if: complexity is handled well, the premise of a growing system is balanced with the rich interaction paradigm as well as possible, and a bridge to reality is made.” The title we gave our project report was: ‘Yes, but… It depends’, which I find a suitable quote to describe the ever promising but complex design space of current age.
