At Midwest UX 14 last weekend, it was really good to see so many people talking about ubiquitous computing/IoT topics. One really nice takeaway from those discussions was learning about Estimote. They make iBeacon sensors and proved dev kits to make simple apps. Their latest product is a set of 10 small stickers that act as sensors, accelerometers, and thermometers. I'm looking forward to getting my hands on these to try out in class.
