Abstract

Un clavier genre piano amélioré comprend un guide d'ondes optique et une feuille à touches. Le guide d'ondes optique retient la feuille à touches sur un support, comme une carte de circuits imprimés de dispositif électronique portatif. La configuration de ce clavier est avantageuse pour que les dessus de touches du clavier puissent adhérer aux touches de manière à assurer une fiabilité à long terme, tout en présentant des touches vite déclenchables et qui fournissent la rétroaction tactile souhaitable pour l'utilisateur.
