This paper describes how usability affects the usage of a computer-based assessment (CBA) instrument. The aim of our current study is twofold: a) the development of a usability improved CBA instrument (ISO 9241-11, 1998; ISO 9241-210, 2010) within the framework of human-computer interaction (HCI) and b) the comparison and evaluation of two concept map applications in regards to the impact that usability has on the assessment interaction. In this study we developed and evaluated two CBA concept map applications. We assessed 60 students aged between 16 and 18 who were asked to conduct concept maps on two different versions of the same knowledge assessment instrument. We observed significant differences regarding two out of three usability criteria of the ISO standard definition: efficiency and satisfaction of the students. Our findings highlight that usability influences the assessment interaction and therefore the chances of the assessment taker to work (successfully) through the assessment. [less ▲]

In this paper we present the DriveLab IVIS testing platform which allows for the same experiments to be conducted both under simulator and real car conditions. Other key aspects of DriveLab is that it is highly modular (therefore allowing the exchange or integration of different components) and that it supports more than one driver. For example we show that the same IVIS devices and scenario can be used with two different 3D engines. The paper provides a technical overview and a brief example of use. [less ▲]

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 ▲]

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.

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.

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 ▲]

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 ▲]

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.

La méthodologie du card-sorting a été utilisée dans le cadre d’un processus de restructuration de multiples sites Internet et Intranet d’une grande entreprise en vue d’élaborer un portail unique. Cette méthodologie offre la possibilité d’investiguer la structure des informations indépendamment des comportements de navigation. La complémentarité des approches des tests d’utilisabilité et du card-sorting permet de se distancier, lors de la phase du card sorting, des difficultés d’utilisabilité liées à l’interface qui est présentée à l’utilisateur pour se focaliser sur des problèmes structurels sous-jacents. L’analyse structurelle des résultats permet d’appréhender les représentations mentales et les catégorisations cognitives qu’effectuent les utilisateurs lorsqu’ils sont eux-mêmes amenés à structurer l’interface.
