Kinesis (keyboard)
Kinesis is a company based near Seattle that offers computer keyboards with ergonomic designs as alternatives to the traditional keyboard design. Most widely known among these are the contoured ''Advantage'' line, which features recessed keys in two bucket-like hollows to allow the user's fingers to reach keys with less effort. Moreover, the keys are laid out in perfect vertical rows to avoid the need for lateral movements during typing. In addition, the modifiers such as enter, alt, backspace, control, etc. are moved to a central location so they can be pressed with the stronger thumbs rather than the pinky fingers. Corporate history Kinesis was founded in 1991 with its headquarters in Bothell, Washington, a suburb of Seattle. The company released its first keyboard, the ''Model 100'' (first in the long-running ''Contoured/Advantage'' line), in 1992. Kinesis's first adjustable keyboard, the ''Maxim'', was released in 1997. In 2000, Kinesis entered a strategic alliance with Crame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Touchpad
A touchpad or trackpad is a pointing device featuring a tactile sensor, a specialized surface that can translate the motion and position of a user's fingers to a relative position on the operating system that is made output to the screen. Touchpads are a common feature of laptop computers as opposed to using a mouse on a desktop, and are also used as a substitute for a mouse where desk space is scarce. Because they vary in size, they can also be found on personal digital assistants (PDAs) and some portable media players. Wireless touchpads are also available as detached accessories. Operation and function Touchpads operate in one of several ways, including capacitive sensing or resistive touchscreen. The most common technology used in the 2010s senses the change of capacitance where a finger touches the pad. Capacitance-based touchpads will not sense the tip of a pencil or other similar ungrounded or non-conducting implements. Fingers insulated by a glove may also be problemat ...

PS/2 Port
The PS/2 port is a 6-pin mini-DIN connector used for connecting keyboards and mice to a PC compatible computer system. Its name comes from the IBM Personal System/2 series of personal computers, with which it was introduced in 1987. The PS/2 mouse connector generally replaced the older DE-9 RS-232 "serial mouse" connector, while the PS/2 keyboard connector replaced the larger 5-pin/180° DIN connector used in the IBM PC/AT design. The PS/2 keyboard port is electrically and logically identical to the IBM AT keyboard port, differing only in the type of electrical connector used. The PS/2 platform introduced a second port with the same design as the keyboard port for use to connect a mouse; thus the PS/2-style keyboard and mouse interfaces are electrically similar and employ the same communication protocol. However, unlike the otherwise similar Apple Desktop Bus connector used by Apple, a given system's keyboard and mouse port may not be interchangeable since the two devices use dif ...

Numeric Keypad
A numeric keypad, number pad, numpad, or ten key, is the palm-sized, usually-17-key section of a standard computer keyboard, usually on the far right. It provides calculator-style efficiency for entering numbers. The idea of a 10-key number pad cluster was originally introduced by Tadao Kashio, the developer of Casio electronic calculators. The numpad's keys are digits to , (addition), (subtraction), (multiplication) and (division) symbols, (decimal point), , and keys.numeric keypad' at FOLDOC Laptop keyboards often do not have a numpad, but may provide numpad input by holding a modifier key (typically labelled ) and operating keys on the standard keyboard. Particularly large laptops (typically those with a 15.6 inch screen or larger) may have space for a real numpad, and many companies sell separate numpads which connect to the host laptop by a USB connection (many of these also add an additional spacebar off to the side of the zero where the thumb is locat ...

Computer Keyboard
A computer keyboard is a peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input method for computers since the 1970s, supplemented by the computer mouse since the 1980s. Keyboard keys (buttons) typically have a set of characters engraved or printed on them, and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence. While most keys produce characters (letters, numbers or symbols), other keys (such as the escape key) can prompt the computer to execute system commands. In a modern computer, the interpretation of key presses is generally left to the software: the information sent to the computer, the scan code, tells it only whi ...

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 ...

Apple Adjustable Keyboard
The Apple Adjustable Keyboard is an ergonomic keyboard introduced by Apple Computer, Inc. in 1993 for the Macintosh family of personal computers. The keyboard attaches to the computer via the Apple Desktop Bus port. The last Apple computer released compatible with this keyboard without using a USB to ADB adapter was the Power Macintosh G3 (Blue and White), as it was the last one with the Apple Desktop Bus. The Apple Adjustable Keyboard came with contoured plastic wrist rests, and a separate keypad with function keys and arrow keys. This was the third and last time Apple offered a separate numeric keypad. Unlike its predecessors, it was not sold separately. The keyboard also included volume buttons and a record button on the right side of the keyboard. It was hinged at the top, allowing the user to adjust the angle between the right and left sides of the keyboard. The split came between the key pairs: 5/6, T/Y, G/H, and B/N. The space bar floated midway between the two parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dvorak Simplified Keyboard
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 ...
