ABSTRACT:
With a view to bringing the cursor into a zone of the image displayed on a screen, the method embodying the invention uses a displacement mode comprising determination and indication on the screen of the orientation and relative direction of displacement one wishes to obtain, this stage being performed by varying the orientation of the index (C) by a first manual command until the required direction is obtained; relative displacement of the cursor (C) in relation to the image, in accordance with the orientation and direction thus determined until it reaches said zone, this displacement being performed by a second command distinct from the first; and validation of the position occupied by the cursor in relation to the image by a third command distinct from the first two. The invention relates equally to conventional management of a cursor, the plotting of the route of an aircraft or even to multidirectional scrolling of an image on a screen.
