A computer program has been used to predict how people are feeling when they type.
In a study participants were asked to type a particular phrase and the program then estimated if they were happy, sad and so on. Surprisingly it was correct 70 per cent of the time, and the findings could lead to smarter artificial intelligence in the future.
The study published in the journal Behavior and Information Technology was carried out by researchers at the Islamic University of Technology in Bangladesh, reports Live Science.
In the research 25 people ranging from 15 to 40 years old were asked to retype two paragraphs from Alice's Adventures in Wonderland written by Lewis Carroll. They also had to enter their emotional state every 30 minutes while doing their regular activities on the computer. This allowed the program an opportunity to understand how their emotions changed their typing style.
Moods tested were joy, fear, anger, sadness, hate, and shame. The result was that the program could identify(识别) a person' s mood correctly 70 per cent of the time. It was most successful in identifying joyfulness with an 87 per cent success ratio, while sadness was the least successful at 60 per cent. The researchers found that the participants were less likely to input (输人) data when they were in a bad mood, which may explain the inexactness of the second result.
However, the findings could have great importance for artificial intelligence, and it may allow computers to get along with us in a friendlier manner, “If we could build any system that is intelligent enough to communicate with humans that is, it can identify user emotions and change its behavior accordingly then using machines could be more effective and friendly.” the researchers wrote.

When visitors to the Palace Museum feel a need to sit down for a cup of tea or find a bathroom without a long line, they soon will be able to turn to their smart phones for the information they need.
This modern day solution comes thanks to an agreement signed on Friday by the museum and Huawei Co., the telecommunication giant, to build a “smart network” using 5G technology. Under the agreement, 5G Wi-Fi signals will cover the Palace Museum, China's royal palace from 1420 to 1911, and the branch museum of the institution under construction in northwestern Beijing.
“It’s essential to always stay close to the latest technology to better serve the public,” said Shan Jixiang, former director of the Palace Museum. Shan said there is still much room for improvement in the handling of a huge number of cultural relics (文物)，such as when the priceless painting Along the River During the Qingming Festival is exhibited again in the future. When it was last exhibited in 2015, visitors stood in long lines until 3 am to get a glimpse. The museum ended up preparing instant noodles to serve the hungry visitors. “I don't want that scenario to reoccur," Shan said. “Our operation can be done in a more scientific way.
The new system will also make use of the closed--circuits television cameras that are set up all over the Palace Museum to safeguard the museum's precious relics. More than 1.86 million of them are housed at the museum, which recorded nearly 20 million visits from the public last year, topping all museums worldwide. “How can we make sure no single visitor who might have evil ideas threatens these treasures?" Shan said. “After adopting the internet of things, we can instantly detect any motion involving the artifacts to prevent such threats.”
The 5G network also will be used to improve remote consultation through webcams, which will facilitate conversations with overseas scholars to jointly find the best answers for restoration and preservation issues.

I' m a seven year old girl but I understand that it is this fact, more than any other, that makes my family different: We don't go to school.
Dad worries that the government will force us to go but it can't because it doesn't know about us. Four of my parents' seven children don't have birth certificates. We have no medical records because we were born at home and have never seen a doctor or nurse. We have no school records because we've never set foot in a classroom. When I'm 9, I will be issued a Delayed Certificate of Birth, but at this moment, according to the state of Idaho and the federal government, I do not exist.
Of course, I did exist. I had grown up watching for the sun to darken, for the moon to drip as if with blood. I spent my summers bottling peaches and my winters rotating supplies.
I had been educated in the rhythms of the mountain, rhythms in which change was never fundamental, only cyclical. The same sun appeared each morning, swept over the valley and dropped behind the peak. The snows that fell in winter always melted in the spring. Our lives were a cycle—the cycle of the day, the cycle of the seasons—circles of lasting change that, when complete, meant nothing had changed at all. I believed my family was a part of this immortal pattern, and that we were, in some sense, eternal(永恒的). But eternity belonged only to the mountain.
All my father's stories were about our mountain, our valley. He never told me what to do if I left the mountain, if I crossed oceans and continents and found myself in a strange land. He never told me how I'd know when it was time to come home.
