La société FingerWorks propose différents claviers ergonomiques basés sur sa technologie MultiTouch, qui intègre frappe et souris sur une même surface sensible. Il n'y a pas de touches mobiles, un 
contact minimum du doigt avec le clavier suffit (ZeroForce touch-typing) ; certains mouvement des doigts sont interprétés comme des mouvements de la souris (gesture input).
Ci-contre le TouchStream LP, un clavier ultra-plat, en 2 parties ajustables dans le plan horizontal (angle et distance). Repliable pour un transport aisé.
Inconvénient de cette technologie : l'absence de feedback tactile. Ci-dessous, le point de vue de Simon Payne (pro eleven) :
The problem on TouchStream is the lack of tactile positioning. It was only after trying TouchStream for approx. 6 weeks that I realized how much a touch typist actually relies on touch. In other words, you automatically center your finger tips according to the feel of the keycaps. As a typist is typing he is continually correcting his hand positioning subconsciously. As long as the typing process continues, each new key hit contributes tactile feedback allowing the hand to re-home itself. If you take away the central dips and - last not least - the edges of the keys, this re-homing mechanism fails completely. The typist's hands will slowly but surely wander away from the optimal position. After a certain time each hand is in some way off center and typos start cropping up.
