Title
(EN) ONE-HANDED KEYBOARD
(FR) CLAVIER POUR UNE SEULE MAIN
Abstract
(EN)
A one-handed keyboard (10) is disclosed which includes a stationary base (12) and a rocking keyboard (18) which is mounted for rocking movement between a normal level position and right and left depressed positions. A selector key (22) is mounted on the rocking keyboard (18) for rocking therewith and also being pivotally mounted for movement between a normal upper or raised positive and a lower position to which it moves when the user rests the palm of his hand on it. A cluster of keys (20, 32, 34) is provided, each of which is multi-function representing a plurality of alpha-numeric characters and/or symbols that can be typed or entered by selective actuation of the character keys, rocking keyboard (18), selector key (22) and a shift key (28) by movements of one hand and movements of the fingers thereof.
(FR)
Un clavier pour une seule main comprend une base fixe (12) et un clavier oscillant (18) monté de façon à osciller entre une position horizontale normale et des positions d'enfoncement à droite et à gauche. Une touche de sélection (22) montée sur le clavier oscillant (18) oscille avec celui-ci et pivote en outre entre une position normale supérieure ou élevée et une position inférieure, qu'elle adopte lorsque la paume de la main de l'utilisateur repose sur elle. Un ensemble de touches (20, 32, 34) à fonctions multiples représente une pluralité de caractères alphanumériques et/ou de symboles qui peuvent être imprimés ou saisis par actionnement sélectif des touches de caractères, du clavier oscillant (18), de la touche de sélection (22) et d'une touche ''majuscules'' (28), au moyen de mouvements de la main et des doigts.
