and plans of the user), most respondents gave a neutral response. Students had an
unfavorable opinion concerning the adaptation of the application to the physical
capacity of the user and to the environment (luminosity, noise and geographic
localization). With accessibility, a problem cited several times, respondents
commented on the smallness of characters, which resulted in poor legibility. A
recurring problem with behavior was the lack of “feedback” during validation
actions.

Average satisfaction levels according to criteria linked to the container
Other general results linked to utility and usability (in the sense of [NIE 93])
were obtained:
- Utility determines whether the interface meets the needs of the user: 55% were
satisfied (satisfaction level [0.75; 1.0]), 40% satisfied ([0.5; 0.75]) and 5% not very
satisfied ([0.25; 0.5]). Users make few mistakes.
- Usability accounts for the quality of the human-machine interaction in terms of
how easy it is to learn and use. The satisfaction rate of the users in terms of usability
is 41% satisfied and 59% very satisfied. These good results can be explained by the
fact that the service is relatively simple, and learning it is quick and easy.
Such results are promising and call for other experiments and developments.
3.6. Discussion about the possibility of generalization relative to personalization
Elements of personalization applied to traveler information have been described
in this chapter. However, it seems to us that it is possible to go much further in
terms of personalization if we generalize the idea of having a detailed schedule of
the activities of the user, made available to intelligent software agents at their
service.
