Abstract
A control mouse has two opposed outward facing digit-engaging portions on a flexible vertical wall and is sized and shaped to be grasped and moved by squeezing force applied by one hand of an operator with a digit engaging each of the digit-engaging portions. The mouse has a pressure operated switch installed so as to be switched to a first state by squeezing force below a threshold force applied between two digits positioned respectively at the digit-engaging portions and switched to a second state by squeezing force above the threshold force. The switch thus controlled by the operator is used to provide signals to the associated computer.
