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 electrically compatible with IBM PC keyboards and Apple Keyboards, using USB connectors. Earlier models used mini-DIN or PS/2 connectors but these are now discontinued.
Lillian Malt ran a secretarial training business from 1955. Based upon her experience of typing errors (having been closely concerned in the printing industry with retraining Linotype operators to use computer keyboards), she had the idea for a typewriter keyboard with the keys arranged to fit different finger lengths, but found no manufacturer willing to work with her. In 1974, Stephen Hobday came to her with a one-handed keyboard that he had designed for the handicapped. Malt made several suggestions for improvement, telling Hobday of her failure to engage the interest of any manufacturers in actually building her ideal keyboard. Hobday told her "You tell me what you want and I'll tell you whether I can build it or not." The first Maltron keyboard was the result of their collaboration.
The full name of the company, PCD Maltron Ltd, stems from Hobday's original electronics firm, Printed Circuit Design Limited, based in Farnborough, Hampshire.

La disposition des touches d'un clavier de saisie permet de saisir les caractères de l'alphabet d'une langue sur une machine à écrire, un clavier d'ordinateur et sur certains appareils électroniques plus récents (téléphone portable, assistant personnel). La plupart des pays utilisent une ou plusieurs dispositions adaptées. Les dispositions de touches sont l'héritage des machines à écrire. Elles ont été adaptées aux claviers d'ordinateurs puis à d'autres périphériques.
Un clavier d’ordinateur est une interface homme-machine munie de touches permettant à l'utilisateur d'entrer dans l'ordinateur une séquence de données, notamment textuelle. Les touches sont généralement des boutons en plastique reliés chacun à un interrupteur électronique. D'un point de vue électronique, elles sont similaires aux boutons d’une souris, d’une télécommande ou d’une manette de console de jeu, mais d'un point de vue pratique, elles ont des qualités propres à leur fonction : un symbole, une lettre, un chiffre, un mot ou une sont habituellement imprimées ou gravées sur la touche, autrement appelée Keycap, afin de permettre à l'utilisateur de saisir les caractères, pour écrire du texte ou pour exécuter une fonction particulière.
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.
