Last week we went on a school trip to a science museum. Ms Liu, the guide, showed us around a smart home.
We started with the front door. Ms Liu asked me to ring the doorbell. I didn't notice the tiny camera that was fixed just above it. After I pressed (按) the doorbell, the camera sent a live video (视频直播) to the home-owners. “They can electronically open the door when they are not at home,” said Ms Liu.
The other thing I couldn't see on the door was a lock. “There must be one,” I thought. At this time, Ms Liu took out a smartphone and put it against the door. And it opened. “Oh, the key is on the smartphone.”
After entering the living room, I saw a computer on a table. By using the computer, the owners can control how much energy is used. In this way, they can manage their living cost. One of the rooms I wanted to see most was the bedroom. To my great surprise, the bed disappeared into the floor at the touch of the smartphone. The window has a smart blind (卷帘). It can be raised and lowered with a voice.
As I left the smart home, I looked back on what I had just seen. Scientists often say that these products are improving our life. I think the technology in the smart home may make us lazier. However, there is no doubt that it will become more popular in the homes of tomorrow.
