Ergonomic Keyboard
An ergonomic keyboard is a computer keyboard designed with ergonomic considerations to minimize muscle strain, fatigue, and other problems. Features The common QWERTY keyboard layout is credited to the mechanical typewriter designed by C. Latham Sholes and patented in 1878; research indicates the layout may have been influenced by telegraph operators. The offset in the columns between rows was designed to accommodate the physical links between each key and the internal mechanisms of the typewriter; as typing duties transitioned to electric (motorized) typewriters and then computers, the layout was retained to ease the transition for users that had already been trained to type. However, the legacy mechanical layout has numerous idiosyncrasies, including the staggered column layout, which can force the user into uncomfortable, repetitive movements and postures. Several potential solutions have been proposed since at least 1926. Ergonomic keyboards, in essence, are created with the ...

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 injury, 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 Institu ...

List Of Repetitive Strain Injury Software
Repetitive strain injuries (RSI) are injuries to the body's muscles, joints, tendons, ligaments, bones, or nerves caused by repetitive movements. Such injuries are more likely if the movements required force or were accompanied by vibrations, compression, hyperextension, or the maintenance of sustained positions. Prolonged use of computer equipment can result in upper limb disorders, notably in the wrist or the back. RSIs are a subset of musculoskeletal disorders. Various software is available to aid individuals in avoiding injury or manage current discomfort/injury associated with computer use. Software categories Software for RSIs generally addresses these functional categories: * Break reminder – Some tools are reminders to take breaks based on factors like elapsed time, how much or how intensely a person is working, natural rest patterns, and times of day. * Activity mitigation – Some tools reduce the amount of typing or mouse clicking (e.g. speech recognition tools, autom ...

Carpal Tunnel Syndrome
Carpal tunnel syndrome (CTS) is a nerve compression syndrome associated with the collected signs and symptoms of Pathophysiology of nerve entrapment#Compression, compression of the median nerve at the carpal tunnel in the wrist. Carpal tunnel syndrome usually has no known cause, but there are environmental and medical risk factors associated with the condition.> CTS can affect both wrists. Other conditions can cause CTS such as wrist fracture or rheumatoid arthritis. After fracture, the resulting swelling, bleeding, and deformity compress the median nerve. With rheumatoid arthritis, the enlarged synovial membrane, synovial lining of the tendons causes compression. The main symptoms are numbness and Paresthesia, tingling of the thumb, index finger, middle finger, and the thumb side of the ring finger, as well as pain in the hand and fingers. Symptoms are typically most troublesome at night. Many people sleep with their wrists bent, and the ensuing symptoms may lead to awake ...

Speech Recognition
Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers. It is also known as automatic speech recognition (ASR), computer speech recognition or speech-to-text (STT). It incorporates knowledge and research in the computer science, linguistics and computer engineering fields. The reverse process is speech synthesis. Some speech recognition systems require "training" (also called "enrollment") where an individual speaker reads text or isolated vocabulary into the system. The system analyzes the person's specific voice and uses it to fine-tune the recognition of that person's speech, resulting in increased accuracy. Systems that do not use training are called "speaker-independent" systems. Systems that use training are called "speaker dependent". Speech recognition applications include voice user interfaces ...

Keyer
A keyer is an electronic device used for signaling by hand, by way of pressing one or more switches. The technical term keyer has two very similar meanings, which are nonetheless distinct: One for telegraphy and the other for accessory devices built for computer-human communication: * For radio-telegraphy, the term "keyer" specifically refers to a device which converts signals from an "iambic" type or "sideswiper" type telegraph key into Morse code for transmission, but excludes the key itself. * For computer human interface devices, "keyer" generally refers to both a single-hand multi-switch and the electronics which interpret the user key-presses and send the corresponding signals to the computer. Radiotelegraph keyers History & telegraphy background In telegraphy, so-called ''iambic'' keys developed out of an earlier generation of novel side-to-side, double-contact keys (called "bushwhackers") and later, mechanical semi-automatic keys (called "bugs"). Semi-automatic keys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DataHand
The DataHand is an unconventional computer keyboard introduced in 1990 by DataHand Systems, Inc., designed to be operated without any wrist motion or finger extension. History DataHand Systems, Inc. was founded in 1985. It was invented by Dale J. Retter and produced as early as 1990. After the initial prototype was released in 1995, DataHand released the Professional and Professional II models with new bodies. The Professional II also has extended programming capabilities over the Professional, being able to record macros of keystrokes for convenient use. DataHand Systems, Inc. announced in early 2008 that it was ceasing to sell its keyboards. The company web site states that due to supplier issues, the company will not sell the DataHand keyboard "until a new manufacturer can be identified". In January 2009, the company's website started taking orders for a "limited number of new DataHand Pro II units". Circa 19 April 2010, DataHand were out of stock. Revival In 2019, a lo ...

Home Row
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 key ...
