A wheelchair having a speed and direction control touchpad. The touchpad comprises two separated semi-conductive film layers, one measuring an X coordinate and one measuring a Y coordinate. When pressure is applied to the layers bringing them into contact with each other, an X, Y coordinate location is produced and the wheelchair is moved in a direction and speed analagous to the location of the pressure applied to the touchpad. A change in location of the pressure will result in a corresponding change in direction and speed. The touchpad also has a neutral or no movement activation point.

Fauteuil roulant possédant un dispositif de télécommande de vitesse et de direction. Ce dispositif de télécommande comprend deux couches semi-conductrices séparées, dont l'une mesure une coordonnée X et l'autre mesure une coordonnée Y. Quand on applique une pression à ces couches, ce qui les met en contact l'une avec l'autre, on produit une localisation de coordonnées X, Y permettant de déplacer le fauteuil roulant dans un sens et à une vitesse analogues à la localisation de la pression exercée sur le dispositif de télécommande. Une modification de localisation de la pression provoquera une modification correspondante de la direction et de la vitesse. Ce dispositif de télécommande possède également un point mort ne déclenchant aucun déplacement.
