Touch typing (also called touch type or touch method or touch and type method) is typing without using the sense of sight to find the keys. Specifically, a touch typist will know their location on the keyboard through muscle memory. Touch typing typically involves placing the eight fingers in a horizontal row along the middle of the keyboard (the ''home row'') and having them reach for other keys. Both two-handed touch typing and one-handed touch typing are possible. Frank Edward McGurrin, a court stenographer from Salt Lake City, Utah who taught typing classes, reportedly invented touch typing in 1888. On a standard keyboard for English speakers the home row keys are: "ASDF" for the left hand and "JKL;" for the right hand. The keyboard is called a QWERTY keyboard because these are the first six letters on the keyboard. Most modern computer keyboards have a raised dot or bar on the home keys for the index fingers to help touch typists maintain and rediscover the correct position on the keyboard quickly with no need to look at the keys. More recently, the ability to touch type on touchscreen phones has been made possible with the use of specialized virtual keyboard software for touch typing. == History == Original layouts for the first few mechanical typewriters were in alphabetical order (ABCDE etc.) but the frequent jams suffered by experienced typists forced the manufacturers to change the layout of the letters, placing keys that are often pressed in a sequence as far as possible from each other. This allows engaging the second printing bar of the typewriter before the first falls down, increasing the speed of the mechanism. Equal distribution of the load over most of fingers also increased the speed as the keys of the mechanical typewriter are more difficult to press. The calculations for keyboard layout were based on the language being typed and this meant different keyboard layouts would be needed for each language. In English speaking countries for example the first row is QWERTY, but in French speaking countries it is AZERTY. Though mechanical typewriters are now rarely used, moves to change the layout to increase speed have been largely ignored or resisted due to familiarity with the existing layout among touch typists. On July 25, 1888, McGurrin, who was reportedly the only person using touch typing at the time, won a decisive victory over Louis Traub (operating Caligraph with eight-finger method) in a typing contest held in Cincinnati. The results were displayed on the front pages of many newspapers.〔(Frank Edward McGurrin ) ''(Very big text, search for the word "500")''〕 McGurrin won US$500 (equivalent to $12,580 in 2012 USD) and popularized the new typing method. Whether McGurrin was actually the first person to touch type or simply the first to be popularly noticed, is disputed. Speeds attained by other typists in other typing competitions at the time suggest that they must have been using similar systems. In 1889 Bates Torrey coined the words "writing by touch" in his article.〔Bates Torrey: Scientific Typewriting, The Writer, Vol. 3, No. 7, pp.152-154, 1889.〕 In 1890 Lovisa Ellen Bullard Barnes defined the words "write by touch" in her book as follows:〔Mrs. Arthur J. Barnes: How to Become Expert in Typewriting: A Complete Instructor Designed Especially for the Remington, Rather J. Barnes, St. Louis, 1890.〕 〔Mrs. Arthur J. Barnes: Complete Caligraph instructor or How to Become Expert in Typewriting, Rather J. Barnes, St. Louis, 1890.〕 The most common other form of typing is search and peck typing (or ''two-fingered typing''). This method is slower than touch typing because instead of relying on the memorized position of keys, the typist is required to find each key by sight and move fingers a greater distance. Many idiosyncratic styles in between those two exist — for example, many people will type blindly, but using only two to five fingers and not always in a systematic way. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Touch typing」の詳細全文を読む スポンサード リンク
