Stephen Hawking, a famous British physicist, died yesterday at the age of 76. Hawking family statement: his courage and perseverance inspired the world. The great physicist is gone forever. As we all know, Hawking is suffering from progressive frostbite, and only three fingers can move. Most of his life is spent in a wheelchair. So how does Hawking talk? What does Hawking talk by? Compared with this, it is a more curious question for many people.
Born in Oxford, England on January 8, 1942, Hawking is one of the most outstanding physicists after Newton and Einstein, known as the 'King of the universe'.
Hawking was diagnosed with muscular dystrophy in 1963. As the condition worsened, there were only three active fingers left. It was technology that changed Hawking's life and spread his theory to the world.
How does Hawking communicate with the outside world? I have to mention some of his good helpers. The infrared sensor sends out a signal with the speed of blinking, detects his eye movements through the infrared, and then transmits them to the computer to convert them into English; the computer needs to adapt to Hawking's blinking speed to accurately type English words; and the language synthesizer can convert words into sounds.
Used to control computers with three fingers
In 1985, Hawking lost his language ability. For a while, he relied on eye contact and needed help to spell out vocabulary, but this kind of communication was very difficult. Later, thanks to programming by California computer expert watt & middot; waltz, Hawking was able to use three fingers to select words on the screen and switch to a speech synthesizer.
David Middleton Mason, of Cambridge regulatory communications, modified a small personal computer and speech synthesizer to fit Hawking's wheelchair, making it easier for him to 'talk'.
Since 1997, Intel has provided Hawking with an auxiliary speech system. The reason is that Moore, the founder of Intel, saw that Hawking's computer used AMD's processor, so he wanted to provide Hawking with a 'real computer'. Later, Intel replaced Hawking's computer every two years and provided support services.
Facial muscle twitch and eyeball indication computer synthesized sound
Since 2005, Hawking can't move his fingers, can't use his hands to control computers, and can only communicate with people through his eyes. Intel found a better solution: through eye tracking, Lenovo input and voice synthesizer playback to help Hawking communicate with the outside world.
Hawking's glasses, about an inch from his right cheek, are equipped with infrared transmitters and detectors that detect muscle activity, pumping facial muscles to transmit information to a computer. Control the infrared sensor with eyeball, select the English letters on the screen, and pass them to the synthesizer for voice after sentence making. According to media reports, Hawking speaks only 5-6 words a minute.
&ENSP; Hawking's' speaking software 'will be free
On December 2, Intel held a conference in London, UK, and announced that it would open the 'speaking software' on the Internet free of charge to disabled people and developers in need in January next year.
Over the past three years, Intel has upgraded its software, reduced the amount of typing required, and doubled its typing speed with predictive input technology. The biggest improvement of the system is the introduction of 'context input prediction' function. Its input system collects and analyzes a large number of articles and personal replies published by Hawking in the past, and establishes a unique data model based on it, so as to accurately analyze and predict the most likely input options of Hawking at present.
Hawking praised this' life changing upgrade ', saying:' I hope it (software) will continue to serve me for the next 20 years. 'Hawking was 72 at the time.
