With the rise of AI (artificial intelligence) combined with IoT (internet of things) the concept of what is a “design thing” shifts from passive artifact to active partner. Capable to perform tasks and make judgments next to us, Things increasingly “work with us” to produce positive change in everyday life. In Cities of Things, we focus on the role that such Things will play in our future cities “as citizens”, moving past the idea of the smart city and smart products as a dashboard and tools for easy living. In the Cities of Things Delft Design Lab we are shaping the future of our cities with intelligent things.
