ABSTRACT:
A cursor controller with a handle which moves in X, Y directions has the handle cantilevered on a upper platform which slides on an intermediate platform in an X direction with the axis of the handle intersecting the effective center of X guide means. And then the intermediate platform slides on a Y guide on a lower fixed platform, all of the foregoing being captured by a top cover. The top cover has a slot through which the handle, which is cantilevered on a bracket fixed to the end of the top platform, extends. The controller can be mounted directly on a keyboard or with a specially shaped enclosure to be operated by one hand.
