Abstract

L'invention concerne un système afficheur au sol (100) qui comprend ou qui est associé à un dispositif de mesure de poids (120, 125, 130). Une sortie du dispositif de mesure de poids peut être traitée par une logique électronique (170) en vue d'afficher des informations correspondantes (119) sur un afficheur électronique (117) du système afficheur au sol. Lesdites informations peuvent se rapporter au poids d'un objet posé sur le système afficheur au sol, par exemple le poids d'une personne debout sur ledit système afficheur au sol. Ce système afficheur au sol peut également afficher un contenu arbitraire comportant des images graphiques et des informations verbales, le contenu pouvant être modifié à la demande. Ledit système afficheur au sol peut en outre comprendre des propriétés réfléchissantes (117, 401).
