Abstract
The invention relates to a method including the steps of: displaying first successive images on a screen; acquiring at least one second image; searching for the position of at least one actuation member relative to the screen based on an analysis of the second image; and modifying at least one of the next first images to be displayed if conditions of determination of the position of the actuation member in the second image are only partially fulfilled.
