If Huang Zhenyu’s mastery of a posh alphanumeric code weren’t spectacular sufficient, take into account the staggering velocity of his efficiency. He transcribed the primary 31 Chinese language characters of Hu Jintao’s speech in roughly 5 seconds, for an extrapolated velocity of 372 Chinese language characters per minute. By the shut of the grueling 20-minute contest, one extending over 1000’s of characters, he crossed the end line with an virtually unbelievable velocity of 221.9 characters per minute.
That’s 3.7 Chinese language characters each second.
Within the context of English, Huang’s opening 5 seconds would have been the equal of round 375 English words-per-minute, along with his total competitors velocity simply surpassing 200 WPM—a blistering tempo unmatched by anybody within the Anglophone world (utilizing QWERTY, at the least). In 1985, Barbara Blackburn achieved a Guinness E-book of World Data–verified efficiency of 170 English words-per-minute (on a typewriter, no much less). Pace demon Sean Wrona later bested Blackburn’s rating with a efficiency of 174 WPM (on a pc keyboard, it ought to be famous). As spectacular as these milestones are, the actual fact stays: had Huang’s efficiency taken place within the Anglophone world, it could be his title enshrined within the Guinness E-book of World Data as the brand new benchmark to beat.
Huang’s velocity carried particular historic significance as effectively.
For an individual residing between the years 1850 and 1950—the interval examined within the guide The Chinese language Typewriter—the concept of manufacturing Chinese language by mechanical means at a price of over 2 hundred characters per minute would have been just about unimaginable. All through the historical past of Chinese language telegraphy, courting again to the 1870s, operators maxed out at maybe just a few dozen characters per minute. Within the heyday of mechanical Chinese language typewriting, from the Twenties to the Seventies, the quickest speeds on file have been simply shy of eighty characters per minute (with nearly all of typists working at far slower charges). When it got here to fashionable data applied sciences, that’s to say, Chinese language was constantly one of many slowest writing techniques on the earth.
What modified? How did a script so lengthy disparaged as cumbersome and helplessly complicated instantly rival—exceed, even—computational typing speeds clocked in different elements of the world? Even when we settle for that Chinese language laptop customers are by some means capable of interact in “actual time” coding, shouldn’t Chinese language IMEs lead to a decrease total “ceiling” for Chinese language textual content processing as in comparison with English? Chinese language laptop customers have to leap by means of so many extra hoops, in any case, over the course of a cumbersome, multistep course of: the IME has to intercept a consumer’s keystrokes, search in reminiscence for a match, current potential candidates, and await the consumer’s affirmation. In the meantime, English-language laptop customers want solely depress whichever key they want to see printed on display screen. What could possibly be easier than the “immediacy” of “Q equals Q,” “W equals W,” and so forth?

To unravel this seeming paradox, we are going to look at the primary Chinese language laptop ever designed: the Sinotype, often known as the Ideographic Composing Machine. Debuted in 1959 by MIT professor Samuel Hawks Caldwell and the Graphic Arts Analysis Basis, this machine featured a QWERTY keyboard, which the operator used to enter—not the phonetic values of Chinese language characters—however the brushstrokes out of which Chinese language characters are composed. The target of Sinotype was to not “construct up” Chinese language characters on the web page, although, the way in which a consumer builds up English phrases by means of the successive addition of letters. As a substitute, every stroke “spelling” served as an digital tackle that Sinotype’s logical circuit used to retrieve a Chinese language character from reminiscence. In different phrases, the primary Chinese language laptop in historical past was premised on the identical sort of “extra steps” as seen in Huang Zhenyu’s prizewinning 2013 efficiency.
Throughout Caldwell’s analysis, he found surprising advantages of all these extra steps—advantages totally unparalleled within the context of Anglophone human-machine interplay at the moment. The Sinotype, he discovered, wanted far fewer keystrokes to discover a Chinese language character in reminiscence than to compose one by means of standard technique of inscription. By the use of analogy, to “spell” a nine-letter phrase like “crocodile” (c-r-o-c-o-d-i-l-e) took much more time than to retrieve that very same phrase from reminiscence (“c-r-o-c-o-d” can be sufficient for a pc to make an unambiguous match, in any case, given the absence of different phrases with comparable or an identical spellings). Caldwell referred to as his discovery “minimal spelling,” making it a core a part of the primary Chinese language laptop ever constructed.
At the moment, we all know this method by a unique title: “autocompletion,” a technique of human-computer interplay by which extra layers of mediation lead to quicker textual enter than the “unmediated” act of typing. Many years earlier than its rediscovery within the Anglophone world, then, autocompletion was first invented within the enviornment of Chinese language computing.
