Abstract
The general field of the invention is that of devices for controlling a computer-based pointer of a computer-based assembly comprising two different computer-based systems, a first secure system comprising at least one first viewing screen and a man-machine interface called CCD controlling the position of the pointer, and a second non-secure system comprising at least one second viewing screen controlled by the same CCD. The control device according to the invention comprises a means called the “CCD manager” belonging to the first system, ensuring the control of the CCD transmission links and comprising the following functions activated when a displacement instruction is transmitted by the user to the CCD, the pointer occupying a first position in the reference plane, determination of the new position of the pointer, determination of the pointer membership area as a function of this new position, authorization of transfer of the displacement instructions coming from the CCD to the secure system or to the open system corresponding to the previously determined membership area.
