In an electronic device, a combination of an electronic visual display (22) on a housing (11) and electronic control circuitry (53) in the housing, the housing having at least one human user depressible surface (80, 82) with associated analog pressure-sensitive element (26) for output of a signal of variable value utilized by the control circuitry to control or manipulate one or more functions of the device. The analog pressure-sensitive element(s) receives pressure applied by a user's finger (76) or thumb to the depressible surface, varied pressure applied by the user determines varied value of the signal. The resultant control manipulation from the analog variable value is in some manner indicated on the display at least at the time of manipulation so that the user receives visual feedback allowing termination, increase or decrease, if needed or desired, of finger pressure on the depressible surface of the analog sensor.
