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 ...
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 provides resistance, while the spring does the capacitive action. [10]
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.
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 "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 ...
Whereas Microsoft mice and Microsoft keyboards were previously controlled from two separate programs – IntelliPoint and IntelliType – the Mouse and Keyboard Center is responsible for both kinds of devices. 32- and 64-bit versions of the software are available, and the program integrates with Windows 8 and above's "Modern UI" interface.
A keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys—sufficient for a full five octaves of range (61 notes).
122-key terminal emulation keyboard: Home/Rule key with arrow keys in a "plus" layout; 24 function keys; 10-key left cluster with terminal commands (Attn, Clear, Pause, ErEOF, etc.). Some models with this P/N exist with the lock light panel present - secondary legends are blue on the version with the LLP.
