Abstract:
A rotational pointing device comprising:a support arm having a first end and a second end, the support arm pivotally mounted for rotating about a fulcrum in a single dimension parallel to the support arm;actuating assemblies disposed proximate to both the first and second ends of the support arm;a control arm extending from the support arm at the fulcrum of the support arm to a distal end;a rotating member for rotating about an axis, the rotating member rotatably mounted at the distal end of the control arm such that the rotating member rotates in a single dimension that is substantially perpendicular to the dimension of the support arm rotation and is movable to cause rotation of the support arm and actuate the actuating assemblies when force is applied to the rotating member in a direction substantially parallel to the support arm; anda position sensor mounted on said control arm proximate to the rotating member, the position sensor for determining the amount of rotation of the rotating member.
