As mentioned by John Gage and James Gosling in the keynote on Tuesday, Sentilla has been monitoring the behavior of people in the Moscone Center. We know when they enter and leave each room and we know the environmental conditions in each room. Together, we have great data that is giving us a good sense of the resources we're using. For example, we can see each time the H/VAC system turns on, we can see an increase in temperature when people (where each person is the equivalent of a 100W light bulb) enter a room, and we can see when the Moscone Center forgets to turn off the lights at night. These are just a few of the interesting bits of information.

To explain this to the audience, Gosling held up a Sentilla pervasive computer in the opening remarks on Tuesday to illustrate how we're injecting intelligence into the real world. Gosling and Gage also showed data that we collected on Monday.

Rich Green followed Gage and Gosling with his keynote that featured Amazon, Sony Ericcson, and others. At the beginning, Green joked, "Jonathan Schwartz turned to me. I don't know if you saw the demo where people are counted going in and out of a room. He turned to me and said 'That's going to be your performance review for the year. I want to make sure that everybody stays throughout the session, and you'll get a pass.'"

Tomorrow, to close the conference, we're going to show the data and Green will get to see his performance review. To be specific, John Gage will show the data to the attendees when he opens Friday's keynote. But that's not all. Sentilla is going to make the audience part of a pervasive application during James Gosling's keynote, where I'll be on stage with Gosling to explain what Sentilla is doing. Be sure to show up and sit up front (or watch on the web) to see more of how we're engaging people and things around us, and how we're turning "dumb" objects into smart things.
