Meet the Team
  • Psychological Science & Engineering of Interactive Technologies

    We are focusing on the psychological science and engineering of interactive technologies to understand and solve real-life problems. We are studying the design of technologies, human cognition, current technologies-in-practice and the situations in which technologies are used: education, business, health, politics, and games. We are developing methods and devices to support better design and decisions, exploring design solutions that support effective practice, and we are engaging with users and stakeholders to change culture and practices where possible.

    HABIT group also brings expertise in the design and evaluation of web and mobile devices. Such a strategy includes: the use of UX guidelines (for both web and mobile), a rich understanding of users and tasks, and user testing to validate the effectiveness of design interventions.


  • Human Behavior & Human Factors

    Human-Centred Design becomes increasingly important and our research focus with practical recommendations for the Web/mobile devices and services. This line of research is enriched with latest findings from cognitive and social psychology, as well as affective design. Particular methodologies used to address real-life problems are: expert review, contextual interviews, user task analysis, survey-based research, structured experiments, and rigorous usability testing. In addition, we explore the role of affect and emotion using biofeedback and physiological assessment to explore affective and emotional components of educational, health and business applications.

  • Adaptive Communication & Personalized Environments

    Designing intelligent systems that are adaptive to context and user needs is a key research area. Challenges today in the Web personalization and adaptation research area range from heterogeneous user needs and user environment issues such as current location and time to multi-channel delivery of applications concerning Web-based content related to services, educational multimedia, entertainment, commerce etc. Nowadays, most Web personalization systems implement various techniques to extract the user profiles, which serve as the main component of such systems. Based on given user preferences and navigation behavior, the Web-based content returns the requested personalized result.

    We conduct applied research in the areas of personalization with emphasis on adaptive hypermedia, Semantic Web, Recommender Systems and Collaborative Filtering approaches to improve interactive experience. In particular, we develop and assess user profiles that includes user perceptual preference characteristics (see also PersonaWeb project). We further analyze the main intrinsic user characteristics such as visual, cognitive and emotional-processing parameters that are incorporated as well as the ‘traditional’ user profile characteristics that together tend to give the most optimized, adapted and personalized outcome. We further design and evaluate adaptation and personalization systems that implement various user profiles.

    Research on Adaptive Communication and Personalized Environments had three main strands:

    1. Theories, Methods, and Applications of Intelligent User Interfaces to align with users’ preferences.

    2. Cognitive and Emotional Processes in educational applications (Web-based and mobile) to increase users’ learning performance and satisfaction.

    3. Mass Customization and personalization strategies and best practices to design products and services that support users’ needs and lead to positive user experience.

    Adaptive communication and personalization been partially driven by a realization that tailored interaction cannot be achieved on a large-scale using traditional, non-adaptive approaches. Adaptive systems endeavor to transform the user from passive receptor of information to collaborator in various tasks and applications.

    Our  research encompasses aspects derived from various fields including computer science, education, human-computer interaction, and psychology.
