The internet of lights

This NYT article has a great quote: "whenever there is lighting, there is data being created." While folks who work with projector-camera systems have known the usefulness of coupled control of illumination and imaging, a similar philosophy has begun to seep into manufacturers of general lighting fixtures. The first wave was the (sort of) obvious class of smart bulbs that allow you to control their color and intensity with your smartphone. Now, one of the new goals is to convert all outdoor lighting into low-level security sensors. Another direction is to control illumination in the workplace over the course of the day, to improve productivity. Lots of low-power, embedded, camera or photodetector-based problems exist in this space.
