陳曉靜

Today cell phones are useful for us. We use cell phones to call our friends， send messages， play games， and even take photos. Now imagine using your cell phones to call your air conditioner. Then you could ask your air conditioner to turn on before you got home. Does this sound impossible to you？ Well， it could become possible soon. In the future， we might use cell phones to control the machines in our homes.

People are working hard to develop different ways to communicate with machines we use every day. For example， it is already possible for cell phone to communicate with laptop computers. Businessmen using laptops during meetings can use their cell phones to work like remote controls. They can use their cell phones to send instructions to computers to turn on， change pictures， and turn off.
