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 operator places their fingers on the positioning articulator and rocks or slides the articulator in the direction they want the cursor to move. And by movement signatures do single and double clicks, and character strings to the host computer, either through the mouse port or the keyboard port. The invention has a top surface, key caps, key interrupters, and cursor positioning device with a means allowing fabrication from stainless steel or less expensive materials. The key and articulator interrupters block optical beams for key and mouse like positioning thus eliminating any physical contact or force from the user. The cursor positioning device being a downwardly positioning interrupter disposed in ring of optical emitters and detectors, whereas depending on the amount of downward movement and the position of downward movement by the positioning interrupter emission is blocked, or partially blocked, between a particular pair of emitters and detectors, that point being the direction of cursor movement. The key and articulator are only removable by releasing them from within the mouse. The invention has a seal protected by the key and articulator whereas only the thick non-flexing portion of the seal is exposed to a user. When keys and articulator are in the most depressed position there is no physical contact with any of the detector surfaces protecting all internal parts from pressure, or force from harsh use or a vandals blow.
