In order to study how the notion of User Experience (UX) evolved over the last few years, an international survey originally conducted in 2008 by Law et al. [1] has been replicated. Its main goal was to get some insights on the points of view from practitioners on the notion of UX. After having slightly adapted the initial (English) survey and having translated it into French and German, more than 758 valid answers have been collected from all over the world. This experience report aims at illustrating some of the challenges involved in the replication of such a study as well as successes and limitations. [less ▲]

Socio-Technical Study On the Effect of Trust and Context when Choosing WiFi Names

We study trust and context as factors influencing how people choose wireless network names. Our approach imagines the mindset of a hypothetical attacker whose goal is to ensnare unsuspecting victims into accessing dishonest WiFi access points. For this purpose, we conducted an online survey. We used two separate forms. The first form asked a random group of participants to rate a list of wireless names according to their preferences (some real and others purposely made-up) and afterwards with implied trust in mind. The second form was designed to assess the effect of context and it asked a different set of respondents to rate the same list of wireless names in relation to four different contexts. Our results provide some evidence confirming the idea that trust and context can be exploited by an attacker by purposely, or strategically, naming WiFi access points with reference to trust or within certain contexts. We suggest, in certain cases, possible defence strategies. [less ▲]

In this paper we provide an overview of the I-GEAR (incentives and gaming environments for automobile routing) project that is intended to reduce traffic congestion in Luxembourg through the use of persuasive gaming. In order to illustrate some of the issues involved we also present an outline concept of a live game in which we propose to encourage the workshop participants to take part. If a sufficient number of workshop participants take part, this real life game could even be used as a small scale study within the project. [less ▲]

In this paper the authors explain the use of gamification as a way to optimize mobility patterns within a heav- ily congested European City. They explore this from two perspectives, first by outlining a gaming concept and secondly by explaining how the use of a mobility game that took place in two locations can be used to explore incentives and design issues.

L’étude se centre sur le processus de reconception de sites web et sur la spécificité des sites à mission de service public. L’intervention ergonomique présentée correspond en effet à une demande de restructuration du portail Internet d’un service administratif. Des entretiens et des tests d’utilisabilité effectués auprès des différents publics cibles ont permis de mettre en évidence : d’une part, l’incidence des facteurs organisationnels sur les " défauts " d’utilisabilité du site, notamment sur sa cohérence interne ; d’autre part, l’existence de décalages importants entre les représentations que les concepteurs ont des besoins des utilisateurs et les besoins réels de ces derniers. La discussion porte sur les implications théoriques et pratiques de tels résultats dans la gestion du processus de reconception d’un portail web et aboutit à la définition de préconisations.
