A data-input device comprises a designator able to point to a position on a screen of a computer system to which the device is intended to be connected and a body intended to be fixed to a workstation, the body comprising a support zone intended to support the hand of an operator as he manipulates the designator. The device further comprises a knob arranged in such a way that it can be manipulated by the fingers of the operator, his hand remaining supported on the support zone. The knob is configured to allow at least two distinct data selections of which one is a choice of values in a series and one is a binary acquisition in relation to the chosen value.

Ergonomics of a data-input device

A data input device comprises a body intended to be fixed onto a workstation, a part that is rotationally mobile in relation to the body, a set of sensors delivering information on the relative position of the mobile part in relation to the body and means for braking the rotational movements of the mobile part in relation to the body. The braking means comprise a friction ring encircling the mobile part, the ring being split and extending mainly in a plane at right angles to an axis of symmetry of the mobile part, an annular spring extending in the plane and radially compressing the friction ring against the mobile part and means for adjusting the length of the annular spring.
