ABSTRACT:
A method for determining an orientation of an object includes determining a plurality of boundary values defining a predetermined range of movement of the object; dividing the range into position segments using the plurality of boundary values; moving a movable portion of the object to a current position; determining a change in object position by comparing a prior object position to the current position; determining the number of position segments corresponding to the change of the object position; outputting a signal corresponding to the number of segments to a control device; determining a scaling value for any or all of the position segments corresponding to a desired position amplification or position attenuation scheme; and controlling movement of a selected image or device based on the amplification or attenuation scheme such that movement of the moveable portion of the object causes disporportional movement of the image or device.
