7．My house is made out of wood，glass and stone．It is also made out of software．
If you come to visit，you'll probably be surprised when you come in．Someone will give you an electronic PIN （个人身份号码） to wear．This PIN tells the house who and where you are．The house uses this information to give you what you need．When it's dark outside，the PIN turns on the lights nearest to you，and then turns them off as you walk away from them．Music moves with you too．If the house knows your favorite music，it plays it．The music seems to be everywhere，but in fact other people in the house hear different music or no music．If you get a telephone call，only the nearest telephone rings．
Of course，you are also able to tell the house if you want something．There is a home control console（控制台），a small machine that turns things on and off around you．
The PIN and the console are new ideas，but they are in fact like many things we have today．If you want to go to a movie，you need a ticket．If I give you my car keys，you can use my car．The car works for you because you have the keys．My house works for you because you wear the PIN or hold the console．
I believe that ten years from now，most new homes will have the systems that I've put in my house．The systems will probably be even bigger and better than the ones I've put in today．
I like to try new ideas．I know that some of my ideas will work better than others．But I hope that one day I will stop thinking of these systems as new，and ask myself instead，"How will I live without them？"
