Smart phones that react to your moods and televisions that can tell it’s you who’s watching are in your future as Intel Corporation’s top technology expert sets his sights on context-aware computing.
Chief technology officer Justin Rattner showed how personal devices will one day offer advice. “How can we change the relationship so we think of these devices not as devices but as assistants or even companions?” he asked.
Handheld devices could combine already common geographic location technology with data from microphones, cameras, heart and body monitors and even brain scans to offer their owners advice that today only a friend or relative could give.
“Imagine a device that uses a variety of sensors to determine what you are doing at an instant, from being asleep in your bed to being out for a run with a friend, ” Rattner said, “Future devices will constantly learn about who you are, how you live, work and play.’’
Rattner also demonstrated a television remote control that figures out who is holding it based on how it is held, and then learns the viewer’s entertainment preferences.
As the world leader for decades in microchips for servers and desktop computers, Intel is hurrying to catch up in the profitable market for smart phones like Apple’s iPhone and Research in Motion’s Blackberry.
Telephones with e-mail, global positioning and media players are pointing the way to a future where ever more functions are packed into ever smaller mobile devices.
The smart phone industry, including technology giants like LG and Samsung, is likely to sell 270 million phones this year and grow 25 percent in 2011, according to market research company IDC.
“I think you can expect to see features that support context-aware computing starting to appear in Intel products in the near future,” Rattner said.
But analysts say Intel faces an uphill battle getting its microchips into new phones as Nvidia, Marvell and Qualcomm have already made headway with cheap, lower-power processors based on designs by ARM Holdings.
Rattner recognized that questions about privacy and people’s willingness to be intimate with their computers will have to be settled before the future generation of smart phones he described takes off.
“If you think identity threat is a problem today, imagine when your whole context is readily available on the Net.”, he said.

For more than six million American children, coming home after school means coming home to an empty house. Some deal with the situation by watching TV. Some may hide. But all of them have something in common. They spend part of each day alone. They are called latchkey children. They’re children who look after themselves while their parents work. And their bad condition has become a subject of concern.
Lynette Long was once the headmaster of an elementary school. She said, “We had a school rule against wearing jewelry. A lot of kids had chains around their necks with keys attached. I was constantly telling them to put them inside shirts. There were so many keys, it never came to my mind what they meant.” Slowly, she learned they were house keys.
She and her husband began talking to the children who had them. They learned of the impact(影响) working couples and single parents were having on their children. Fear is the biggest problem faced by children at home alone. One in each three latchkey children the Longs talked to reported being scared. Many had nightmares and were worried about their own safety.
The most common way latchkey children deal with their fears is by hiding. It might be in a shower stall, under a bed in a closet. The second is TV. They’ll often play it at high volume. It’s hard to get statistics on latchkey children, the Longs learned. Most parents are slow to admit they leave their children alone.

Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life.
In some modern countries it has for some time been fashionable to think that by free education for all — one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degree; they refuse to do what they think “low” work; and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor; we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns…
In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one’s work. Only such a type of education can be considered valuable to society.

I went to my favorite restaurant one evening to have supper. I knew the owner very well. 1 I was waiting for the soup to arrive, I looked around to see if I knew anyone in the restaurant. It was 2 that I noticed a man sitting at the corner table 3 watching in my direction, as if he knew me. The man had a newspaper open 4 him, which he was 5 to read, though all the while I could see that he was keeping an eye on me. When the waiter brought the soup, the man was clearly 6 by the familiar way in which the waiter and I talked to each other. He became even more puzzled as time went on and it grew more and more obvious that I was well 7 in the restaurant. In the end he got up and went to the kitchen. After a few minutes he came 8 again, paid his bill and left without 9 looking in my direction.
When I finished and was 10 to pay my bill, I called the owner over and 11 him what the man had wanted. The owner at 12 didn’t want to tell me. I 13 “ Well”, he said “ that man was a detective.” “ 14 ?” I said, much surprised. “ he followed you here because he 15 you were the man he was looking for,” the owner said. “ He showed me a photo of the 16 man. He certainly looked 17 you! Of course since we know you here. I was able to make him 18 that he had made a mistake.” “ It’s 19 I came to a restaurant where I’m where I’m known,” I said, “ otherwise I 20 have been taken to police station!”
