Abstract: Loop member 10 for pointing devices for computers, consisting of a number of axially extending thin wires 11, 12, 13, 15, 16, twined in each other in such a way that the wires 11, 12, 13, 15, 16 work as links that can rotate a small angle in relation to each other. The wires 11, 12, 13, 15, 16 together build up a tangentially bendable cylinder, the cross-section of which is stretched into an elongate shape via two supports. Between the supports, there is a thin plate on which the upper part of the cylinder rests. The upper surface of the cylinder can be reached by a user through an opening in an apparatus box and be moved in a two-dimensional way, the move being detected and giving rise to the corresponding move of a pointer or the like on a screen. Suitable embodiment for said supports and peripheral mechanics is also shown.

Abstract: The present invention includes a device suitable for the displacement of a cursor or its equivalent on a monitor. The device comprises a loop (10), mounted in tension around and between two separate shaft devices (20, 30) that can be translated, at least one of which is arranged such that it can be displaced and rotated.
