We propose an operational framework for a social, technical and contextual analysis of security. The framework provides guidelines about how to model a system as a layered set of interacting elements, and proposes two methodologies to analyse technical and social vulnerabilities. We show how to apply the framework in a use case scenario. [less ▲]

Concept maps: A useful and usable tool for computer-based knowledge assessment? A literature review with a focus on usability

The concept map is now widely accepted as an instrument for the assessment of conceptual knowledge and is increasingly being embedded into technology-based environments. Usability addresses how appropriate (for a particular use) or how user-friendly a computer-based assessment instrument is. As we know from human-computer interaction research, if the interface is not user-friendly, a computer-based assessment can result in decreased test performance and reduced validity. This means that the usability of the interface affects the assessment in such a way that if the test is not user-friendly, then the test taker will not be able to fully demonstrate his/her level of proficiency and will instead be scored according to his/her information and communication technology (ICT) literacy skills. The guidelines of the International Test Commission (2006) require usability testing for such instruments and suggest that design standards be implemented. However, we do not know whether computer-conducted concept map assessments fulfill these standards. The present paper addresses this aspect. We conducted a systematic research review to examine whether and how researchers have studied and considered usability when conducting computer-based concept map assessments. Only 24 out of 119 journal articles that assessed computer-based concept maps discussed the usability issue in some way. Nevertheless, our review brings to light the idea that the impact of usability on computer-based concept map assessments is an issue that has received insufficient attention. In addition, usability ensures a suitable interaction between test taker and test device; thus, the training effort required for test use can be reduced if a test's usability is straight forward. Our literature review, however, illustrates that the interplay between usability and test use training has mostly been neglected in current studies. [less ▲]

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

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 ▲]

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 ▲]

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 ▲]

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 ▲]

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.

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.
