Abstract
A pointing device for a computer, having switching mechanisms with perceptively differing actuation forces, is disclosed. In one embodiment, the pointing device comprises a housing, a sensor, a first switching mechanism and a second switching mechanism. The sensor is disposed within the housing and translates movement into an electrical signal. The first switching mechanism is also disposed within the housing and has a first predetermined actuation force. The second switching mechanism is also disposed within the housing and has a second predetermined actuation force. The second predetermined actuation force is perceptively different than the first predetermined actuation force.
