Abstract
A system for delivering and displaying messages in a display device part of a network comprising: a set of display devices (100, 100', 101, 102, 103) and a set of presence detection sensors (200, 200', 201, 201', 202, 202') configured to provide a sensor state which is related to the presence of users. Each of the display devices is configured to periodically sense the sensor states of a subset of said presence detection sensors. Each of the display devices is configured to compute a presence probability estimate, function of said sensor states, and whose value covariates with the probability that a user is in a neighbour area of said display device. Each display device is configured to display messages whose presence probability estimate is above a predetermined threshold.
