Loop member (1) 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. |
