Abstract
A global positioning system device having capability for reception of global positioning system information or data; the device including a hand-held housing, a general image display in the housing, a proportional sensor for creating a varying value according to varying depression applied by a finger of a human user to a depressible surface of the sensor. Multiple proportional sensors are sometimes utilized. In one preferred embodiment the proportional sensor(s) include resilient dome cap(s) for providing tactile feedback to the finger depressing the depressible surface. Circuitry within the housing is connected to the sensor for reading the varying value from the sensor and causing representative varying of the imagery shown by the display.
