This interactive demo features MIXER, a Virtual Learning Environment (VLE) consisting of synthetic characters representing the various actors in a scenario group difference scenario. MIXER creates virtual dramas by using interactive narrative with those characters. The goal is to enable children to identify social rule differences, by interacting with one of the characters to which they become empathic. MIXER is evaluated in the UK and Germany with children aged 9 to 11 years. The video for the demo content can be found at: http://youtu.be/iKIndn5NPaQ.

Designing and executing test cases for security-critical protocols is a technically complicated and tedious process. SecureMDD is a model-driven approach that enables development of security-critical applications based on cryptographic protocols. In this paper we introduce a method which combines the model-driven approach used in SecureMDD with the design of functional and security tests. We construct and evaluate new modeling guidelines that allow the modeler to easily define such test cases during the modeling stage. We also implement model transformation routines to generate runnable tests for actual implementation of applications developed with SecureMDD. © 2013 Elsevier B.V. All rights reserved.

While a lot of research has been devoted to improving the security and the reliability of ubiquitous display environments, work on the user experience factor of trust is still scarce. To ensure that ubiquitous environments find acceptance among users, the user experience factor of trust should, however, not be underestimated. In this paper, we present a decision-theoretic approach to trust management that we consider particularly appropriate when a system has to balance the benefits and risks of a decision carefully. In the paper, we define decision policies that help maintain trust in critical situations, such as the loss of sensor data or the presence of unknown people. The approach has been employed in three interactive applications that have been developed as part of a university-wide ubiquitous displays management system. © 2012 Springer-Verlag Berlin Heidelberg.

User-Centred Prototyping (UCP) tools are expected to support interface developers in order to more efficiently, effectively and satisfactorily design, evaluate and analyse user-friendly products by an all-in-one tool solution. We developed such a UCP tool called MoPeDT that supports the user-centred development of interactive evolutionary prototypes for mobile phones in the context of the Internet of Things. In this paper we address our tool features for the design, evaluation and analysis phase that mostly base on meaningful features from related tools. Additionally, we cover potential enhancements to former UCP tools in order to support interface developers with a wide-ranging playground to investigate the user's behaviour and preferences. The paper also describes MoPeDT's evaluation with 20 students over one month that investigated the interface developer's efficiency, effectiveness and satisfaction when applying our UCP tool. As an outcome of this study we describe potential benefits and problems that might be of interest to other developers of UCP tools. © 2010 ACM.
