Touch typing (also called blind typing, or touch keyboarding) is a style of typing. Although the phrase refers to 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—the term is often used to refer to a specific form of touch typing that involves placing the eight fingers in a horizontal row along the middle of the keyboard (the home row) and having them reach for specific other keys. (Under this usage, typists who do not look at the keyboard but do not use home row either are referred to as hybrid typists.) 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 home row touch typing in 1888. On a standard QWERTY keyboard for English speakers the home row keys are: "ASDF" for the left hand and "JKL;" for the right hand. 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 positioning of the fingers on the keyboard keys.

History

Original layouts for the first few mechanical typewriters were in alphabetical order (ABCDE etc.) Changes were made, mostly responding to suggestions from telegraphists that were among the first users.^[1] Common letters were moved towards the center and into the upper row. Z and S are close to each other because the American Morse codes of Z and a common digram SE (both   ▄ ▄ ▄  ▄ ) are near the same, so the telegraphist often needs to wait for more signals before understanding the content. The view that the layout was intentionally redesigned to slow down the operator, to prevent jamming the mechanism, is widespread but not correct.^[1]

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, an American man, Frank Edward 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.^[2] McGurrin won US$500 (equivalent to $13,304 in 2019 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.^[3]

In 1889, Bates Torrey coined the words "writing by touch" in his article.^[4] In 1890, Lovisa Ellen Bullard Barnes defined the words "write by touch" in her book as follows:^[5][6]

To learn to write by touch, that is, with only an occasional glance at the key-board, sit directly in front of the machine. Keep the hands as nearly as possible in one position over the key-board.

In 1985, Touch Typist Typing Tutor, developed and released by Sector Software is an early example of typing tutor software.^[7]

Touch typing is contrasted to search and peck, also known as hunt-and-peck or two-fingered typing. Instead of relying on the memorized position of keys, the typist finds each key by sight and moves their finger over to press it, usually the index finger of their dominant hand. This method is considered inferior as not only is it slower than touch typing, the typist would have to have their fingers travel a greater distance.

Various other styles in between those two exist—for example, using a search-and-peck method, but with an increased number of fingers; typing without looking at the keyboard, but using fewer than the eight fingers that the home row method uses (commonly, the omission of the little finger as the weakest finger that many will find difficult to hit keys with due to either less strength, less dexterity, or both); moving their entire hand to reach for the desired key; or only moving when a key needs to be pressed instead of always returning to home row after every keystroke.

Advantages

Speed

Touch type training can improve an individual's typing speed and accuracy dramatically. Speeds average around 30–40 WPM (words per minute), while a speed of 60–80 WPM is the approximate speed to keep up with one's thoughts. A Microsoft survey suggested that many managers expect employees to be able to type at a minimum of 50 WPM.^[8] Professional career typists can exceed 100 WPM repeatedly and continuously (secretarial, data entry, etc.). Routine practice is required to maintain a high typing speed and accuracy.^[9]

Reduced switching of attention

A touch typist does not need to move the sight between the keyboard (that is obscured with fingers and may be poorly lit) and other areas that require attention. This increases productivity and reduces the number of errors.

Reduced neck strain

Touch typing helps improve posture and reduce neck pain by keeping one's eyes focused on the display and avoiding a constant need to glance at the keyboard.^[10]

Disputes over advantages

There are many other typing styles in between novice-style "hunt and peck" and touch typing. For example, many hunt-and-peck typists have the keyboard layout memorized and are able to type while focusing their gaze on the screen. One study examining 30 subjects, of varying different styles and expertise, has found minimal difference in typing speed between touch typists and self-taught hybrid typists.^[11][12] According to the study, "The number of fingers does not determine typing speed... People using self-taught typing strategies were found to be as fast as trained typists... instead of the number of fingers, there are other factors that predict typing speed... fast typists... keep their hands fixed on one position, instead of moving them over the keyboard, and more consistently use the same finger to type a certain letter." To quote doctoral candidate Anna Feit: "We were surprised to observe that people who took a typing course performed at similar average speed and accuracy as those that taught typing to themselves and only used 6 fingers on average". However, the study has been criticised for only selecting subjects with average typing speeds up to 75 words per minute, thus lacking generalizability for faster typists.

Training

A touch typist starts by placing their fingers on the "start position" in the middle row and knows which finger to move and how much to move it for reaching any required key. Learning typically includes first printing exercises containing only letters on or near the standard position and then gradually mastering other rows. It is important to learn placing fingers into the start position blindly as the hands are frequently raised from the keyboard to operate the line feed lever (in the past) or (more recently) the computer mouse. The keys F and J frequently contain some surface features that allow the typist to recognize them by touch alone, thus removing the need to look down at the keys to reset the fingers at the home row.

The typing speed can be increased gradually and speeds of 60 WPM or higher can be achieved. The increase in speed varies between individuals. Many websites and software products are available to learn touch typing and many of these are free. Learning touch typing can be stressful both to the fingers as well as the mind in the beginning, but once it is learned to a decent level, it exerts minimal stress on the fingers.^[13] For individuals with past typing experience, learning to touch type is particularly difficult due to motivational reasons: the initial performance level in touch typing is far lower than in visually guided typing; therefore it does not initially seem worthwhile to study touch typing.^[14]

Typing speed generally improves with practice. While practicing, it is important to ensure that there are no weak keys. Typing speed is typically determined by how slow these weak keys are typed rather than how fast the remaining keys are typed. If a stage is reached where irrespective of the amount of practice, typing speed is not increasing, it is advisable to let some time pass and continue serious practice thereafter as typing speeds typically tend to increase with time even when no serious practice is done.

Home row

The "home row" is the center row of keys on a typewriter or computer keyboard. On the most common type of English language keyboard, the QWERTY layout, "A S D F" and "J K L ;" are the home keys on the home row.

The middle row of the keyboard is termed "home row" because typists are trained to keep their fingers on these keys and return to them after pressing any other key that is not on the home row.

Some keyboards have a small bump on certain keys of the home row. This helps returning the fingers to the home row for touch typing.

For instance, to type the word poll on a QWERTY keyboard, one would place all of one's fingers on the home row. (The right hand should be covering "J K L ;" with the right thumb on the space bar while the left hand covers "A S D F" with the left thumb on the space bar.) The typist will then use their little finger to reach for the "P" key located just above the semicolon and then return the little finger back to the semicolon key from which it originated. The ring finger, located on the "L" key will be moved directly upwards to press the "O" key and then back. Finally, the same ring finger will remain on the "L" key and press it twice. Experienced typists can do this at speeds of over 100 words per minute.^[15]

Other methods

A method taught since the 1960s (and perhaps earlier): The left little finger is used for the keys 1 2, the ring finger for 3, the middle — 4, the left index finger is responsible for 5 and 6. On the right side of the keyboard: index — 7 and 8, middle — 9, ring — 0 and the little — all other keys on the right side of the upper row. These two methods likely reflect the layout of the typewriters from early days when some of them had no 0 and/or 1 keys.

A third method is a mix of both methods: The left hand works exactly the same as above, and the right hand as in the base method (the right index finger is used for digit 7 only). Some people consider this more ergonomic since the fingers of both hands generally move to the inside.

There exist special ergonomic keyboards designed for each typing method. The keyboard is split between the keys 5 and 6 or 6 and 7.

Some specialized high-end computer keyboards are designed for touch typists. For example, many manufacturers provide blank mechanical keyboards. A trained touch typist should not mind using a blank keyboard. This kind of keyboard may force hunt and peck users to type without looking, similar to Braille keyboards used by the visually impaired.
