  • the invention relates to a method of utilizing an interactive wireless communication networ in a defined logically ivided area of a localization-independent audience with portable communication units for audiovisual messages, in which the available information depends on the position of the individual communication unit within the area, and which may map the pattern of movement of the audience.
  • the object of the system is to continuously communicate topi- cal visual updatable messages, e.g. for information or advertising purposes, to a major number of visitors moving unpredictably within a defined area as for example a gallery exhibition or a shopping mall.
  • Such wireless electronic information units which may be operated interactively for choice of language and similar, are given to the visitors to be carried around by them, for example m a gallery.

  • Purposeful information of current interest to a customer who has put himself into an active buying situation by turning up, able to pay, in for example a shopping mall has been given low priority in advertising, but some variants are known, like placarding, customer newspapers, messages called over the loud speaker network, huge piles of uniform articles, establishing of bargain stands, implementation of article demonstrations.

  • the system lacks possibilities of interactive use and differentiation between users; the base station transmits the same information repeatedly, and does not contain any other way either to dif- 5 ferentiate the message than proximity to the transmitter.

It is assumed that the base unit and the individual communication unit are time synchronized.

Abstract

L'invention porte sur un procédé d'utilisation d'un réseau de communication hertzien interactif dans une zone définie, divisée de façon logique, d'une audience indépendante d'une localisation, à l'aide d'unités de communication portables destinées à la transmission de messages, les informations disponibles dépendant de la position dans laquelle se trouve l'unité de communication portable dans la zone, et pouvant correspondre au profil de déplacement de l'audience. On obtient des informations électroniques relatives à la positon, d'une unité de bases (1) dotée d'antennes (2) à une audience dont le déplacement n'est pas déterminé, au moyen de mesures géométriques ordinaires prises à partir d'au moins deux antennes. En vue de séparer les informations, la zone est divisée en une grille logique de champs/zones identifiés par des références de coordonnées, des informations hiérarchiques et/ou liaisons à d'autres sources d'informations ayant été affectées à un autre champ logique. Chaque unité de communication (3, 4, 5, 6, n) peut communiquer de manière interactive avec l'unité de base (1) en activant des liaisons d'informations transmises, et est autorisée par un sélecteur (7, 8, 9, 10) de signaux à choisir d'autres informations. Les informations obtenues à partir de l'unité de base (1) peuvent être utilisées pour établir une correspondance avec le profil mobile de l'audience. L'unité de communication (3, 4, 5, 6, n) est pourvue d'une alarme qui est déclenchée, par exemple, au moment de la fermeture, si l'unité est physiquement déplacée de la zone correspondante ou analogue.
