Apparatus comprises; a processor 11 with an output terminal 22B and an input terminal 22A for an electrical signal; a controller 13 for receiving a signal from the output terminal and returning the signal to the input terminal, the controller comprising pressure-sensitive means responsive to change in pressure thereon to vary the signal as a function of the change; and a screen 12 for displaying an image, the image influenced by the processor based on the varied signal. The signal might be an audio signal that is transmitted from and received by a combination headphone-loudspeaker port at the processor. The controller might be a stylus having a nib 15. The nib is displaceable by being pushed which moves a member or wiper 18 of a potentiometer 16, and this alters the resistance or impedance of the circuit which in turn modifies the signal. The screen might be a touch-sensitive screen. |
