Membrane keyboard as used on the East German Robotron Z1013. A membrane keyboard is a computer keyboard whose keys are not separate, moving parts, as with the majority of other keyboards, but rather are pressure pads that have only outlines and symbols printed on a flat, flexible surface. Very little tactile feedback is felt when using such a ...
The Happy Hacking Keyboard (HHKB) is a small computer keyboard produced by PFU Limited of Japan, codeveloped with Japanese computer scientist and pioneer Eiiti Wada. [1] Its reduction of keys from the common 104-key layout down to 60 keys in the professional series is the basis for it having smaller overall proportions, yet full-sized keys.
Kinesis's first adjustable keyboard, the Maxim, was released in 1997. [3] In 2000, Kinesis entered a strategic alliance with Cramer, Inc. of Kansas City, which manufactured ergonomic seating. Kinesis took over production for the Cramer Interfaces chair arm-mounted split keyboard, [4] releasing a revised version as the Kinesis Evolution in 2001. [5]
A keyboard which utilizes these abilities include the Realforce RGB. IBM's Model F keyboard is a design consisting of a buckling spring over a capacitive PCB, similar to the later Model M keyboard, but instead used membrane sensing in place of a PCB. The Topre Corporation design for switches uses a conical spring below a rubber dome. The dome ...
The "sudden collapse" of the chiclet keyboard (along with the movement of the key) provides a greater tactile feedback to the user than a simple flat membrane keyboard. Most often the tops of the keys were hard, but sometimes they were made of the same material as the rubber dome itself. Other versions of the chiclet keyboard omit the upper ...
The Model F was a series of computer keyboards produced mainly from 1981–1985 and in reduced volume until 1994 by IBM and later Lexmark. [1] Its mechanical-key design consisted of a buckling spring over a capacitive PCB, similar to the later Model M keyboard that used a membrane in place of the PCB.
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 Apple Keyboard was a more solid version of the Apple Desktop Bus Keyboard and optionally included with the Macintosh II and SE in 1987. (This shared layout with the A9M0330 meant that it retained the Escape and Control keys introduced by that keyboard, as did the M0115 Apple Extended Keyboard and subsequent Macintosh keyboards. [16])
