- 18 - ABSTRACT OF THE DISCLOSURE A data input device has a moveable element, for example, a circular knob. This is moveable in two different directions, one of which can be circular and the other can be along the axis of the knob. A display unit is preferably associated with the screen, so that rotation of the knob in a first direction causes a pointer to scroll through a menu on the screen. Actuation of the knob in the second direction causes the different screens to be selected, or selected items on the screen to change their state. It can be used as a sole input device for microprocessor-based devices.
