When things start talking back, you’ve become part of an Internet of Things. Auto-sensoring, basic intelligence, interaction, we’re increasingly part of a world were things and living souls are equally connected. The fridge is a node just as you are. Volume #28 dives into these new dimensions of reality, into the consequences for design and for our understanding of our own position in the world. Coders and architects are different beings and speak different languages, this issue seems to conclude. Since merging virtual and physical requires knowledge about both worlds, this reality should be overcome. So this Volume is not just about framing the issue, but also about indicating a practice in the making: we call it correlation designing.
