Description

TECHNICAL FIELD OF THE INVENTION The present invention aims at a screen support, an information dissemination device used during a professional training and a method of displaying information by a screen attached to such a support. It applies, in particular, to the display of information during a professional training. STATE OF THE ART Vocational training usually involves a group of people gathered during a seminar.

In current systems, training staff provide instruction based on a presentation posted once for all participants. The disadvantage of these systems is that there is no interactivity between the participants and the information displayed nor any interactivity between the participants. The information displayed is, moreover, strictly identical for each participant. In other current systems, training participants each have a computer or tablet and training is provided interactively but always in the same way for each participant and without interaction between participants.

In other current systems, the participants each have an identical information medium and these participants exchange orally with each other. The disadvantage of these systems is the multiplication of devices increasing the overall cost of implementing the training. In general, the training tends to move towards playful and interactive aspects. The notion of interactivity presupposes the notion of structuring exchanges in order to normalize the result of these exchanges. Current systems do not allow structuring of conversations between users in the absence of a member of the training staff. Since electronic media have to replace paper media, the current solutions are not satisfactory with regard to their effect on the interactivity between: - the participants and the information and - the participants between them.
