Tucked away in a secret location, a team of Sony engineers is working on the ultimate house of the future, where you can control everything in the house just from the touch of a button or a swipe on the screen of your mobile phone. Imagine going into your own private, 3D theater and in one tap, lowering curtains, dimming the lights, locking the front door, and starting your favorite movie. The house isn't just a high-end playground, either. It's a testing ground.
