A desktop operated computer control mouse including a housing, electronic circuitry within the housing, a user manipulable rotatable ball for pointing control, a plurality of finger depressible buttons exposed on the housing and interfacing with sensors electrically connected with the circuitry. At least some of the finger depressible buttons are for user selection of signals to be sent to the computer for window or screen scroll control, and are associated with sensor(s) which are pressure-sensitive analog sensors structured for varying electrical conductance through at least three readable states or values. The readable states are dependant upon depressive pressure applied to the sensor(s) through the finger depressible button(s). The circuitry is structured to read the at least three readable states of the pressure-sensitive analog sensor(s) and to produce signals representing the state or value of the sensor(s). In one embodiment, the analog sensor(s) are elastomeric dome-cap sensor(s) including pressure-sensitive variable-conductance material positioned over proximal circuit elements of the circuitry. In another embodiment the sensors are packaged sensors including button depressible concavo-convexed conductive disks positioned to compress pressure-sensitive variable-conductance material forming at least a portion of an electrical flow path through the packaged sensor. The analog sensors are associated with window or screen scroll control, and provide user determinable scroll rates dependant upon pressure applied by the user through ergonomically correct finger depressible buttons. Methods of use and manufacture are also disclosed.
