ABSTRACT:
A cursor positioning device that can be sealed if the environment requires sealing, that can withstand harsh use, and can position the cursor easily and quickly. In operation the where the operator places their fingers on the positioning articulator and rocks or slides the articulator in the direction they want the cursor to move. And with movement signatures do single and double clicks, and character strings to the host computer, either through the mouse port or the keyboard port. The key and articulator interrupters block optical beams for key and mouse like positioning thus eliminating any physical contact or force from articulator to detecting optics. Cursor position is positioned by an interrupter disposed in a ring of optical emitters and detectors, whereas depending on the position of movement by the positioning interrupter emission is blocked, or partially blocked, between a particular pair or pairs of emitters and detectors, that particular pair or pairs being the direction of cursor movement. The amount of articulator movement is the distance the cursor moves.
