Towards New Interactive Displays
in Stations and Airports
10.1. Introduction
In train, tram, bus stations and airports, the supply of information to passengers
is an essential task for the smooth running of their journey. However, the multitude
of information present in these places often leads to a multiplication of display
devices and overloads passengers with information that does not necessarily concern
them. This can only lead to the confusion of users and a lot of time spent searching
before finding the desired information. This is particularly true in the case of public
display devices, such as the display screens that can be found in airports; see
Figure 10.1. This type of screen displays information concerning all available
flights, whereas a passenger considered individually will only be interested in one
flight. This therefore leads the user to carry out an information search that can be all
the more tedious when there is a great deal of information present.
Based on the principle that there is no point in presenting a person with
information that does not concern him, our objective is to make sure that the
presentation of information is targeted at the users who receive it. We therefore
suggest designing an
opportunistic
system for presenting information, which only
provides information to the users situated in its proximity.
