Although it might sound a lttle far from you, living in a "smart" city like this could happen sooner than you think.Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a "telepresence system(远程遥控系统)-- allowing users to control the heating and locks, take part in video meetings, and receive education, health care and government services. Around the city, escalators ( 自动扶梯 ) will only move when someone is on them, and offices and schools will all be connected to the system.The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business.
