    1. 1. Leveraging Human-CenteredComputing with Trust Do trust matters? @ Sónia Sousa, 2013
    2. 2. 3This presentation covers...• Contextualization• The research goals and questions• The overall research methodology• The expected contributions and results – Results so far – Some assumptions and questions @ Sónia Sousa, 2013
    3. 3. 4Contextual aim• Design and develop strategies to foster Trust among systems designers• Develop and evaluate a toolset to monitor Trust levels• Facilitating the deployment of trust level regulation interventions. @ Sónia Sousa, 2013
    4. 4. 5Contextual aim• Taking into consideration – knowledge sharing • the ways we perceive and handle information – Learning interactions • the way we use our cultural context and relate to our environment – Individuals active participation • The way we create and maintain social relations – Individuals cooperation • the way we go about (cooperate) in our work and life @ Sónia Sousa, 2013
    5. 5. WHYHuman-Centered Computing….
    6. 6. 7Human-Centered Computing• Closely related to field – human-computer interaction; and ce • focused on ergonomics and the usability of computing artifacts – information science • focused on practices surrounding the collection, manipulation, and use of information;• Is an emerging interdisciplinary academic field concerned with – Computing and computational artifacts as they relate to the human condition. @ Sónia Sousa, 2013
    7. 7. WHY TRUST….
    8. 8. 9 Trust? (assumptions) • Trust is in fact a crucial element – in human relationship • Trust is a fundamental for influencing – individuals participation; and – Cooperation • Consequences – Trust engenders more efficient collaboration – Trusting • Influences the level of commitment • Reduces the level of uncertainty • Influences the performance(e.g. Yan, 2010; Mcknight, 1996; Constantine, 2006, Preece, 2004) (e.g. Garfinkel, 1963; Coleman, 1988; Fukuyama, 1995, Weber, 2003)

    10. 10. Research strategies Approach one Approach two• research questions • research questions – How do the large user base – divided in two sets of questions systems and technologies 1. Develop and evaluate a foster trust? toolset to monitor trust – To what extent were these levels; and systems and technologies 2. The deployment of designed for trust? interventions designed to – How to systematically support regulate (moderate, improve, designing for trust? recover) trust levels. @ Sónia Sousa, 2013
    11. 11. 12The toolset to monitor trust• Research questions – What data can be used to monitor trust? – How often should data be sampled to generate robust trust indicators? – How should data samples be collected taking into account that the impact of the sampling process in the generation of confidence indicators should be minimized? – What metrics should be used to express trust levels? – How should trust indicators be interpreted? @ Sónia Sousa, 2012
    12. 12. 13Deployment of interventions• Design interventions to regulate (moderate, improve, recover) trust levels – What interventions result in favorable changes in trust indicators? – How to facilitate the design and deployment of these interventions? @ Sónia Sousa, 2012

    16. 16. 17Framework of reference• Builds on my previous body of knowledge – Aiming to leverage the sustainability of Digital ecosystems, by • Perceiving Trust as an interaction facilitator construct.• Bridges various disciplines • On Human-Centered Computing (HCC) focus on – humans with systems, – humans with technologies, – humans with their environment, – humans with humans integration • On the previously knowledge on Trust • On previous knowledge of distance education paradigms @ Sónia Sousa, 2013
    17. 17. 18Specifically...• Observing on three main trust factors – the course mediators, • Trust towards Teacher’s/facilitators and learner’s interactions, – Course learning artifacts; and – Course learning environment.• Focus on a socio-technical model of Trust – Which represent the interceptions of • Human-Computer Trust Components; and • The dynamic nature of Trust in relationships @ Sónia Sousa, 2013
    18. 18. 19Measuring and dimensions scales• The Measuring scales – Student’s trust predispositions; and – Student’s rational and emotional perceptions;• The Dimensions scales: – Students’ Motivation; – Willingness towards the learn activities; – Trust predisposition towards three main factors – Students’ rational perception towards • competence, predictability and reliability – Students irrational perceptions on • reciprocity and benevolence and and honesty @ Sónia Sousa, 2013
