Maltron Keyboard
PCD Maltron Ltd, trading as Maltron, is a manufacturer of ergonomic special-needs keyboards. It was founded by South African-born inventor Lillian Malt and manufacturer Stephen Hobday. Maltron specialises in making keyboards for the prevention and etiological (root cause) treatment of repetitive strain injury. Maltron manufactures several models of keyboard, in varying levels of adaptation. Malt's original invention and the company's flagship design, the Fully Ergonomic 3D Keyboard, is the most highly adapted; it incorporates a curved surface in which the keys' angles and depths are staggered to compensate for the different lengths and placement of the fingers. Customers can choose an integral trackball at extra cost. Other types include single-hand keyboards, a flat version of the fully ergonomic keyboard, a keyboard designed to be used by a single digit or headstick or mouthstick, and a robust expanded keyboard for people with cerebral palsy. Maltron keyboards are electricall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Computer Hardware
Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is "hard" or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware. Von Neumann architecture The template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic lo ...

Cherry (keyboards)
Cherry AG (formerly Cherry Corporation and stylized as CHERRY) is a German computer peripheral-device maker. The company has its roots in the United States and is headquartered in Germany. It has additional offices in the United States, France, and China. They manufactured a large range of products including sensors, vibrators and automotive modules until 2008, when Peter Cherry, the son of Walter L. Cherry, sold his company to ZF Friedrichshafen AG, a German supplier to the automotive industry. Cherry was renamed ZF Electronics GmbH, while the Cherry brand was continued only for its computer input devices. Since the beginning of 2016 this product line has been operating independently on the market as the Cherry Group. After an eight-year partnership with ZF Friedrichshafen AG, Cherry (the computer input device manufacturer) was sold to GENUI Partners in October 2016. In October 2020, Cherry was acquired by the private equity firm Argand Partners and as of June 2021 is now l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Microsoft Ergonomic Keyboards
Microsoft has designed and sold a variety of ergonomic keyboards for computers. The oldest is the Microsoft Natural Keyboard, released in 1994, the company's first computer keyboard. The newest models are the Sculpt Ergonomic Keyboard (2013), the Surface Ergonomic Keyboard (2016), and the Microsoft Ergonomic Keyboard (2019). Models In general, ergonomic keyboards are designed to keep the user's arms and wrists in a near-neutral position, which means the slant angle (the lateral rotation angle for the keys in each half relative to the axis of the home row in a conventional keyboard) is approximately 10 to 12.5°, the slope (the angle of the keytop surfaces starting from the front edge closer to the user towards the top of the keyboard, relative to a horizontal plane) is -7.5°, and the tent or gable angle of each half (the angle of the keytops from the center of the keyboard towards its left and right edges, relative to the horizontal desk surface) is 20 to 30°. ;Notes Natura ...

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, or the maintenance of sustained or awkward 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. This article discusses and lists some specialized software that 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 click ...

Pronation
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatomica ...

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 keyboa ...

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 ...
