Abstract
A mechanical user interface includes a supporting plate and a slider adapted to slide on the supporting plate. A position encoder is attached to the supporting plate to monitor movement of the slider. The position encoder provides an electrical output indicative of the position of the slider on the supporting plate. A sensor may also be provided to detect when the slider is at a zero position, thereby allowing absolute rather than relative, position data to be obtained. In a computerized film editing system, when the absolute position is less than a given threshold, the mechanical user interface may be used to advance film by a single frame. Otherwise the position may be translated to a frame per second rate.
