Les systèmes d’infotainment embarqués dans les véhicules sont amenés à se multiplier davantage dans les années à venir. Bien que cette tendance mette en évidence la nécessité de comprendre et d’optimiser la charge attentionnelle placée sur le conducteur, force est de constater qu’il existe peu de données et d’outils communs pour la conception et l’évaluation de tels systèmes. Nous présentons deux directions que la communauté doit poursuivre pour améliorer cette situation ainsi qu’une plate-­‐forme de simulation automobile que nous développons et dont l’architecture favorise la ré-­‐utilisation des composants logiciels et la reproductibilité des résultats.

Gamification as a Methodology: A Multi-Part Development Process

Gamification is often thought of as the end result or outcome of a project. In this paper we explore how it can also be adopted during the conceptual design stage using metaphorical games and as a method of testing concepts within a more advanced simulation environment. We explore this from the perspective of the I-GEAR project where it is used as one of many methods in the design of a commuter mobility game. [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 ▲]

Studies in Socio-Technical Security Analysis: Authentication of Identities with TLS Certificates

in IEEE TrustCom (2013)

Authenticating web identities with TLS certificates is a typical problem whose security depends on both technical and human aspects, and that needs, to be fully grasped, a socio-technical analysis. We ... [more ▼]

Authenticating web identities with TLS certificates is a typical problem whose security depends on both technical and human aspects, and that needs, to be fully grasped, a socio-technical analysis. We performed such an analysis, and in this paper we comment on the tools and methodology we found appropriate. We first analysed the interaction ceremonies between users and the most used browsers in the market. Then we looked at user's understanding of those interactions. Our tools and our methodology depend on whether the user model has a non-deterministic or a realistic behaviour. We successfully applied formal methods in the first case. In the second, we had to define a security framework consistent with research methods of experimental cognitive science. [less ▲]

Replicating an International Survey on User Experience: Challenges, Successes and Limitations

in ACM SIGCHI 2013 Conference on Human Factors in Computing Systems (2013)

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 ▲]

Gaming concepts and incentives to change driver behaviour

In this paper we present a novel concept that deals specifically with changing driver behaviour in order to reduce traffic congestion. The project I-GEAR (incentives and gaming environments for automobile routing) aims to understand the motivations that drivers have while undertaking the daily commute and then to provide them with a range of incentives to change their behaviour. A key focus within the project is on ways in which the problem could potentially be solved without recourse to an expensive infrastructure project. Our solution to this problem was to move the problem of traffic management onto everyday mobile devices. In the following paper we outline the background to the problem, concepts relating to pervasive gaming, existing explorations of incentives and gaming approaches as well as our basic concept and project methodology.

Pervasive Gaming as a Potential Solution to Traffic Congestion: New Challenges Regarding Ethics, Privacy and Trust

The following paper presents a review of the ethical, privacy and trust aspects relating to pervasive gaming in particular within the domain of traffic congestion. The paper deals explicitly with the challenges involved that fall between the gaps standard ethical practice and scientific research when studies comprise of those in the lab (where collection and use is heavily controlled) and those which take place in the wild where there is the requirement to share data possibly with external parties. Also where the nature of such work is at the borders of the concept of traditional study and a commercial running prototype. [less ▲]
