Welcome to the Electronic Village to explore new ways of language teaching and learning.

    Angel Garcia Crespo is a computer engineer at Carlos III University of Madrid in Spain. His group has invented a new way for deaf-blind people to “watch” TV. The idea for the technology grew out of previous work by his group. The team had already worked on making audiovisual(视听的) materials accessible to people with either vision or hearing disabilities. But the group wanted to help people with both challenges. So they asked some deaf-blind people what would help.

    In addition to relying on their sense of touch to communicate, deaf-blind people can also get and send information with a Braille line. The Braille system uses patterns of raised dots to stand for letters and numbers. A Braille line is an electronic machine with a changeable Braille display. Dots rise up or drop down based on the information sent to the machine.

    Now the new system changes TV signals to data a Braille line can use. “The key to the system is the possibility of using subtitles(字幕) to collect TV information, " Garcia Crespo explains. "Subtitles travel with the image(影像) and the audio in electromagnetic waves we don't see. But an electronic system can keep those waves."

    First, a computer program, or app, pulls out the subtitles and visual descriptions from the broadcast signal. The system then combines the information and changes both into data for Braille.

    Now another app gets to work, which sends the data out to people's Braille lines on demand. “This is done in real time, in less than a second, " Garcia Crespo says. This lets a deaf-blind person "watch" TV as it's broadcast. The system will work with various Braille lines, as long as there's a bluetooth connection available. Now, the system is only used in Europe, and it should soon be available in the US.

    Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you'll have no trouble answering these questions.

    Most of us observed much more as children than we do as adults. A child's day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的）to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.

    The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they'd felt cold water at first.

    Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.

    The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what's around them. I asked them what they'd seen. "Oh, a few birds," they said. They seemed bent on their destinations.

    Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.

    I took a journey to New York, US several months ago. It was the first time I had been abroad. It was also the first time I had taken a trip by myself. I had great enthusiasm and high hopes, and I wasn't let down.

    It's hard to describe how I felt when I arrived at the airport in New York. Looking at people of different races and nationalities passing by and hearing different languages all around me, I couldn't say anything for a long time. I had never understood the cultural diversity of the US so clearly and closely before.

    The following days were even more impressive. We integrated(融入)into the forest of concrete and cement(混凝土和水泥). We waved to the Statue of Liberty; we looked down at the busy island of Manhattan; we looked at well-known universities—Harvard of ancient Egypt.

    Then we visited some well-known university—Harvard, Yale, Princeton and Columbia—each with its own appealing and time-honored history. But what all these universities have in common is their peaceful academic atmospheres witch you could feel everywhere. I was impressed by the libraries, decorated just like cathedrals(教堂), and the laboratories just next to the classroom. My dream is to return to those places as an international student.

    Finally came our destinations—the Model United Nations conference at the University of Chicago. Students from various countries arrived to act as United Nations delegations and share their opinions about global issues.

    As a non-native speaker, I felt that competing against native speakers was a very tough task. But it was also a rare change to improve my English and I couldn't throw it away. With perseverance and devotion. I got used to talking to other delegations naturally. Although I didn't win any awards, the chairman praised me at the closing ceremony for my excellent performance. That made me feel really proud.

    This trip brought me unforgettable and valuable experiences that will benefit me forever.

    Convincing someone to change their mind is really the process of convincing them to change their tribe (部落). If they abandon their beliefs, they run the risk of losing social ties. You can't expect someone to change their mind if you take away their community too.

    The way to change people's minds is to become friends with them, to combine them into your tribe, to bring them into your circle. Now, they can change their beliefs without the risk of being abandoned socially.

    The British philosopher Alain de Botton suggests that we simply share meals with those who disagree with us: "Sitting down at a table with a group of strangers has the incomparable and odd benefit of making it a little more difficult to hate them without punishment. Prejudice and conflict between groups of people from different nations or races feed off abstraction. However, during a meal, something about handing dishes around, unfolding napkins (餐巾纸) at the same moment, even asking a stranger to pass the salt makes us less likely to hold the belief that the outsiders who wear unusual clothes and speak in distinctive accents deserve to be sent home or attacked. For all the large-scale political solutions which have been proposed to ease racial or cultural conflict, there are few more effective ways to promote tolerance between suspicious neighbours than to force them to eat supper together."

    Perhaps it is not difference, but distance that produces tribalism and unfriendliness. As proximity increases, so does understanding. I am reminded of Abraham Lincoln's quote, "I don't like that man. I must get to know him better." Facts don't change our minds. Friendship does.

    The Japanese writer Haruki Murakami once wrote, "Always remember that to argue, and win, is to break down the reality of the person you are arguing against. It is painful to lose your reality, so be kind, even if you are right."

    When we are in the moment, we can easily forget that the goal is to connect with the other side, cooperate with them, befriend them, and integrate them into our tribe. We are so caught up in winning that we forget about connecting. It's easy to spend your energy labeling people rather than working with them.

    The word "kind (family and relatives)" originated from the word "kin (old fashion of family and relatives)." When you are kind to someone, it means you are treating them like family. This, I think, is a good method for actually changing someone's mind. Develop a friendship. Share a meal. Gift a book. Be kind first, be right later.
