In interviews, I often talk about the desire of digital property owners to cross over into the physical world, since it represents a fabulous new, uncharted territory. Robotic sensing and robotic actuation provide the means for that digital-physical jump, and the Nest thermostat is one such example, with sound and pyroelectric sensors that can detect whether or not you are home and active. With Nest’s purchase, Google has taken on new physical information in the home, and the Wall Street Journal’s Role Winkler and Alistair Barr report today on Nest’s announcement that it will share occupant status information with Google’s services, and with third party companies as well. The upside of this fluid connection between your home movements, home sensors, internet-connected devices planted on your dining room wall, and Google’s broad array of services have to do with convenience: your Android phone tells your house that you’re unexpectedly heading home, turn the thermostat on; your garage door notices you have left home, close the garage door you accidentally left open; your phone is off but you are home when you need to be at a meeting, email you and get you out of the house. But of course, all this convenience will come along with the interesting profit-motive question: how can the behavioral information itself, or the convenience afforded by such interconnections, transform data across millions of households into revenue? Time will tell just how digital-physical bridges become moneymaking mints, and I guarantee some of the smartest minds are working on that.
