For Internet addicts, it could be the ultimate way to stay in touch without going out—an entire apartment turned into a giant, online screen. A Spanish design agency named Think Big Factory has made it available by creating an intelligent house.
　　The entire system of the house can be controlled from anywhere by using gestures or speech. The walls show Facebook updates and life-sized friends during video chats by using projectors and sensors, just like a giant iPad.
　　Everything in the house can be used to communicate, and the interface is ubiquitous. Through projections that are activated by the presence of a person, we can control everything with the movement of the hands, including switching the lights on and off and turning on electrical household appliances, etc.
　　The main interface of the system is in the living room, where you can see social networks, browse magazines, and play music just using gestures. The system uses sensing cameras to track users, aiming to replace the keyboards and remote controls and allowing users to swipe in mid-air to move through menu.
　　Much of the technology in the intelligent house is invisible, so the house does not look different from a common house.
　　The first inhabitant has already moved into the experimental apartment. He is using some parts of the house, and researchers are learning from that so as to develop and improve the technology.
