The meaning of the ESC button on the computer keyboard

According to foreign media reports, Jack Dennerlein, a human-computer interaction expert at the Harvard School of Public Health, said that the ESC button on the computer keyboard is a rather special button that was promoted in the 1970s and 1980s. The revolution in the computer industry.

????Dan Leren said that ESC buttons are a way for people to interact with computers, just as people are talking to computers: stop the work in your hands, I now need to take over control. In other words, this is a reminder to the computer that it is still a machine, and human beings are its masters. If the astronauts in 2001 Space Odyssey 2001: A Space Odyssey have such a convenient button, they can immediately stop the evil computer Hal Hal from sinning.

????In fact, the ESC button was designed by a programmer named Bob Bemer of IBM in 1960. He originally tried to solve the problem of a tower: to make computers from different vendors different. The code is communicated. Benmore invented the ESC button, allowing programmers to switch from one encoding to another. Then, when the computer code is standardized, the ESC button becomes an abort button on the PC computer, which is used to pause the computer.

????Why did you choose the word Escape to escape? Ben Moore can use other words, such as stopping Interrupt, but he finally chose ESC to commemorate his own worries. He is a sentimental person. As early as the 1970s, he began to worry about the Y2K millennium bug. Now, our computers are relatively more stable, and no one needs to panic about it. But Bob said he is still using the ESC button. He said: It is always good to be prepared.

????Why are outdated buttons like ESC still going to exist? There are some legacy legacy items in our equipment. In the past hundred years, when people want to write something, they will sit down in front of a typewriter. But today’s computers look very different, they are like smartphones. Maybe after 10 or 15 years, the whole keyboard will become very strange. At that time we might say: Remember the tools we entered in the past? It is the keyboard.

????In the future, how do we manipulate computers without typing? Think about Wii and Kinect, or a dedicated input device for games like Guitar Hero. We may see more and more such new input methods, such as speech recognition and audio control, such as Siri.
