The control arrangement for a marker (140) on a computer (130) screen or display comprises a hand unit (10) with two probing components (20,30) fitted along two fingers of a user of the computer and which are brought into contact with each other in a point of intersection (80) controlling the marker position on the screen. The probing components are connected to a processor unit (120) for determining the point of intersection between them when they locate against each other and for controlling the marker position in two identical right-angled directions dependent upon the point of intersection. The processor unit incorporates devices for measuring the resistance in the probing components for determining the coordinates for the point of intersection between them. |
