Wristband plugs you into smart buildings

SWELTERING in the office while your colleague shivers under layers of extra clothing? Just register your discomfort by tapping a button on your wrist and let the room do the rest. That's one of the ideas behind WristQue, a project at the Massachusetts Institute of Technology that aims to create a low-power wristband device that works with sensors embedded in buildings to monitor how you feel and continually adjust the lighting and temperature to keep you happy. WristQue is the key to controlling "the immersive world of interactive media that will one day surround us", says Joe Paradiso, director of the Responsive Environments Group at MIT's Media Lab, who is working with colleagues to design it. Each 3D-printed, plastic WristQue band will contain a microprocessor and will be packed with environmental sensors to detect changes in temperature, humidity and light. It will be fitted with a chip that uses ultra-wideband radio signals to pinpoint the user's location and will be able to communicate wirelessly with sensors fitted in smart buildings.
