10:10 Nathalie Colineau and Cecile Paris: Can Beneficial Habits Be Induced through Reflection
Abstract: Persuasive technology aims at changing people's behaviour. In health, in particular, such technology tries to promote healthy habits. Systems using persuasive techniques typically provide an external motivation (e.g., a reward). They often face two challenges: what reward will make people change their behaviour, and how can people maintain a healthy habit once the reward has been removed. Both are heavily debated issues. In our work, we look at encouraging reflection and see if it can lead to an intrinsic motivation, which in turn can affect behaviour. If it is possible to induce an intrinsic motivation, the two challenges mentioned above would disappear. In this paper, we present a study we conducted in the health domain: we tried to encourage people to reflect on their lifestyle and find ways to improve it. We present some of the interesting findings regarding intrinsic motivation and behavioural change from our study.

Abstract. Effective delivery of dysphagia exercises requires intensive repetition, yet many brain injury survivors demonstrate difficulty adhering to home programs. The Technology Assisted Prompting (TAP) system provides a novel method to deliver intensive in-home therapy prompts, scheduled to fit the patient's TV watching schedule. This paper reports on a study that compared the effectiveness of the TAP system to typical practice on program adherence, satisfaction, and caregiver burden. A within-participant alternating treatment design with random assignment of treatment condition compared exercise program adherence across TAP and typical practice delivery conditions, replicated across three participants. Data included quantitative program completion rates, satisfaction survey reports, and caregiver burden questionnaire results, as well as qualitative interview findings. A large treatment effect was demonstrated for two participants; exercise program completion rates increased by 6-17 times typical practice levels with the TAP system. TAP supported sustained practice for the third participant despite minimal differences between conditions. Participants reported high satisfaction and endorsed the TAP system. There was no significant change in caregiver burden.

13:00-14:30 13:00 Alexander Felfernig, Ingo Pribik, Sophie Steinparz, and Gerhard Leitner: Towards Persuasive Technologies for Improved Software Quality
Abstract. Complexity metrics and refactoring rules have been developed with the goal to estimate the quality of software artefacts and to systematically improve the quality of those artefacts. There is still a significant gap between the prevalent quality of software artefacts and the potential quality which could be achieved if software developers would adopt well-known software development practices represented in complexity metrics and refactoring rules. The major goal of our work is to develop persuasive mechanisms that pro-actively motivate software engineers to improve the overall quality of software artefacts. We have implemented these mechanisms as a plug-in for the software development environment Eclipse. The major goal of this short paper is to introduce the idea of persuasive technologies for improved software quality, to report the current status of our work, and to discuss issues for future research.

13:20 Idoia Cearreta and Nestor Garay-Vitoria: Ontology for adapting interactions between humans and systems able to manage affective states
Abstract. This paper presents an approach to user-based adaptation of communication. This is achieved by modelling the interaction between computer-based systems and humans, taking into account the context which surrounds them and without filtering the information which is implicitly transmitted (affective states, mood, emotions) by humans. Thanks to this adaptation, it is possible to influence users in order to get the necessary motivation and achieve the objective of the interaction. The presented adaptation and modelling are being used in affective mediation via computer-based systems.

13:40 Hien Nguyen and Judith Masthoff: Developing Personalised Digital Behaviour Interventions: A Multi Stage Process
Abstract. Digital behaviour interventions are becoming more and more popular and significant. While there are plenty of successful stories, there are as many others that failed. So what distinguish an effective from an ineffective intervention? In this paper, we present a number of key principles in designing effective digital interventions. These principles include: tailoring the intervention to each individual, increasing the level of interactivity, using theories of behaviour and behaviour change as the intervention's theoretical basis, and using multiple behaviour change techniques simultaneously. These principles in turn have great implications and raise numerous research challenges on the process of developing a personalised digital intervention.
