A manually-operated control for generating a vector signal comprises a handle with an elongate axis pivotally mounted to the housing for universal rotation about a pivot point on the axis of the handle. An imaged surface moves in two directions with the rotation of the handle about two perpendicular axes intersecting at the pivot point. A camera and LED are focused on the imaged surface. A microprocessor-based controller inputs and processes images sequentially input from the camera for detecting and quantifying the movement of the imaged surface in two directions and generates a vector signal indicative thereof.

Une commande manuelle pour générer un signal vectoriel comprend une manette munie d'un axe allongé monté de façon pivotante sur le logement pour une rotation universelle autour d'un point de pivotement sur l'axe de la manette. Une surface imagée se déplace dans deux directions lors de la rotation de la manette autour de deux axes perpendiculaires se recoupant au point de pivotement. Une caméra et une DEL sont focalisées sur la surface imagée. Une commande à microprocesseur entre et traite les images générées en séquence par la caméra pour la détection et la quantification du mouvement de la surface imagée dans les deux directions, et génère un signal vectoriel indicatif de ce mouvement.
