The Intel Collaborative Research Institute (ICRI), a joint collaboration between UCL and Imperial ran from 2012- 2018. The research was concerned with user-centered and technical aspects of sustainable and connected cities. For example, the capstone project focused on developing novel IoT technologies at scale and testing them in situ, in the harsh realities of the city. A core theme was how to explicitly bring citizens into the loop of Urban IoT; we employed citizen engagement to enable local communities to be more proactive in collecting and making sense of urban data for their own personal/ community gains while providing valuable new data in the form of citizen experiences and feedback.
