One Hand Typing
The idea of one-hand typing is to touch type using only one hand (e.g. the left one), or mainly one hand. Its history and application are closely related to keyboard research on QWERTY and Dvorak keyboard layouts. Typing with one hand can be done in a number of ways, and novel approaches are still emerging. People handle this situation in different ways and the solution depends on whether it is necessitated by a temporary condition, as well as the pupil's physical abilities, muscle strength, and cognition and memory. Therefore, existing approaches may fit different expectations. Benefits and drawbacks One-handed typing can be useful in situations where one would usually need to move their dominant hand between one's keyboard and mouse or if the typist hands are otherwise occupied. A potential drawback of this method is that it can be straining on the typist's hands, which can lead to repetitive strain injury.

Touch Typing
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 keyboa ...

QWERTY
QWERTY () is a keyboard layout for Latin-script alphabets. The name comes from the order of the first six Computer keyboard keys#Types, keys on the top left letter row of the keyboard ( ). The QWERTY design is based on a layout created for the Sholes and Glidden typewriter and sold to E. Remington and Sons in 1873. It became popular with the success of the Remington No. 2 of 1878, and remains in ubiquitous use. History The QWERTY layout was devised and created in the early 1870s by Christopher Latham Sholes, a newspaper editor and printer who lived in Kenosha, Wisconsin. In October 1867, Sholes filed a patent application for his early writing machine he developed with the assistance of his friends Carlos Glidden and Samuel W. Soule, Samuel W. Soulé. The first model constructed by Sholes used a piano-like keyboard with two rows of characters arranged alphabetically as shown below: - 3 5 7 9 N O P Q R S T U V W X Y Z 2 4 6 8 .

Dvorak Keyboard Layout
Dvorak is a keyboard layout for English patented in 1936 by August Dvorak and his brother-in-law, William Dealey, as a faster and more ergonomic alternative to the QWERTY layout (the ''de facto'' standard keyboard layout). Dvorak proponents claim that it requires less finger motion and as a result reduces errors, increases typing speed, reduces repetitive strain injuries, or is simply more comfortable than QWERTY. Dvorak has failed to replace QWERTY as the most common keyboard layout, with the most oft pointed to reason being QWERTY was popularized 60 years prior to Dvorak's creation and Dvorak's advantages are debated and relatively minuscule. However, most major modern operating systems (such as Windows, macOS, Linux, iOS, Android, ChromeOS, and BSD) allow a user to switch to the Dvorak layout. The layout can be chosen for use with any hardware keyboard, regardless of printed characters on the keyboard. Several modifications were designed by the team directed by Dvorak or ...

Keyboard Layout
A keyboard layout is any specific physical, visual or functional arrangement of the keys, legends, or key-meaning associations (respectively) of a computer keyboard, mobile phone, or other computer-controlled typographic keyboard. is the actual positioning of keys on a keyboard. is the arrangement of the legends (labels, markings, engravings) that appear on those keys. is the arrangement of the key-meaning association or keyboard mapping, determined in software, of all the keys of a keyboard; it is this (rather than the legends) that determines the actual response to a key press. Modern computer keyboards are designed to send a scancode to the operating system (OS) when a key is pressed or released: this code reports only the key's row and column, not the specific character engraved on that key. The OS converts the scancode into a specific binary character code using a "scancode to character" conversion table, called the keyboard mapping table. This means that a physical keyb ...

Repetitive Strain Injury
A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. Other common names include repetitive stress disorders, cumulative trauma disorders (CTDs), and overuse syndrome. Signs and symptoms Some examples of symptoms experienced by patients with RSI are aching, pulsing pain, tingling and extremity weakness, initially presenting with intermittent discomfort and then with a higher degree of frequency. Definition Repetitive strain injury (RSI) and associative trauma orders are umbrella terms used to refer to several discrete conditions that can be associated with repetitive tasks, forceful exertions, vibrations, mechanical compression, sustained or awkward positions, or repetitive eccentric contractions. The exact terminology is controversial, but the terms now used by the United States Department of Labor and the National Institute of Occupational Safe ...

Modifier Key
In computing, a modifier key is a special key (or combination) on a computer keyboard that temporarily modifies the normal action of another key when pressed together. By themselves, modifier keys usually do nothing; that is, pressing any of the , , or keys alone does not (generally) trigger any action from the computer. For example, in most keyboard layouts the Shift key combination will produce a capital letter "A" instead of the default lower-case letter "a" (unless in Caps lock or Shift lock mode). A combination of in Microsoft Windows will close the active window; in this instance, Alt is the modifier key. In contrast, pressing just or will probably do nothing unless assigned a specific function in a particular program (for example, activating input aids or the toolbar of the active window in Windows). User interface expert Jef Raskin coined the term " quasimode" to describe the state a computer enters into when a modifier key is pressed. Modifier keys on personal com ...

Muscle Memory
Muscle memory is a form of procedural memory that involves consolidating a specific motor task into memory through repetition, which has been used synonymously with motor learning. When a movement is repeated over time, the brain creates a long-term muscle memory for that task, eventually allowing it to be performed with little to no conscious effort. This process decreases the need for attention and creates maximum efficiency within the motor and memory systems. Muscle memory is found in many everyday activities that become automatic and improve with practice, such as riding bikes, driving motor vehicles, playing ball sports, typing on keyboards, entering PINs, playing musical instruments, poker, martial arts, and dancing. History The origins of research for the acquisition of motor skills stem from philosophers such as Plato, Aristotle and Galen. After the break from tradition of the pre-1900s view of introspection, psychologists emphasized research and more scientific metho ...

Xkcd
''xkcd'', sometimes styled ''XKCD'', is a webcomic created in 2005 by American author Randall Munroe. The comic's tagline describes it as "a webcomic of romance, sarcasm, math, and language". Munroe states on the comic's website that the name of the comic is not an initialism but "just a word with no phonetic pronunciation". The subject matter of the comic varies from statements on life and love to mathematical, programming, and scientific in-jokes. Some strips feature simple humor or pop-culture references. It has a cast of stick figures, and the comic occasionally features landscapes, graphs, charts, and intricate mathematical patterns such as fractals. New cartoons are added three times a week, on Mondays, Wednesdays, and Fridays. Munroe has released five spinoff books from the comic. The first book, published in 2010 and entitled ''xkcd: volume 0'', was a series of select comics from his website. His 2014 book '' What If?'' is based on his blog of the same name that ans ...

Chorded Keyboard
A keyset or chorded keyboard (also called a chorded keyset, ''chord keyboard'' or ''chording keyboard'') is a computer input device that allows the user to enter characters or commands formed by pressing several keys together, like playing a " chord" on a piano. The large number of combinations available from a small number of keys allows text or commands to be entered with one hand, leaving the other hand free. A secondary advantage is that it can be built into a device (such as a pocket-sized computer or a bicycle handlebar) that is too small to contain a normal-sized keyboard. A chorded keyboard minus the board, typically designed to be used while held in the hand, is called a keyer. Douglas Engelbart introduced the chorded keyset as a computer interface in 1968 at what is often called "The Mother of All Demos". Principles of operation Each key is mapped to a number and then can be mapped to a corresponding letter or command. By pressing two or more keys together the user ca ...

Human Multitasking
Human multitasking is the concept that one can split their attention on more than one task or activity at the same time, such as speaking on the phone while driving a car. Multitasking can result in time wasted due to human context switching and becoming prone to errors due to insufficient attention. If one becomes proficient at two tasks, it is possible to rapidly shift attention between the tasks and perform the tasks well. Etymology The first published use of the word "multitask" appeared in an IBM paper describing the capabilities of the IBM System/360 in 1965. The term has since been applied to human tasks. Research Since the 1960s, psychologists have conducted experiments on the nature and limits of human multitasking. The simplest experimental design used to investigate human multitasking is the so-called psychological refractory period effect. Here, people are asked to make separate responses to each of two stimuli presented close together in time. An extremely genera ...
