Personalized and Trusted Behaviour Change Technologies

建议的研究将推动电脑系统领域的最新技术，以支持人们改变自己的行为，为自己和社会带来利益。它将开发新颖的个性化说服技术和激励机制，这些技术和机制将得到用户的信任，不仅包括用户，还包括他们的社交圈（朋友、邻居、家庭成员），以支持他们实现改变行为的目标。我将从经验（通过用户研究和观察）、理论（通过设计信任和激励机制，并通过理论分析和模拟对其进行评估）和实践（通过在实际系统中设计和评估激励机制）上探索有效的激励机制。我将从社会心理学中选择动机和认知偏差理论作为出发点，指导说服策略和激励机制的设计，以激励用户从事有益的行为。应用领域包括网上购物、自我完善（学习）、健康的生活方式、在工作和休闲中实行安全行为，以及增加孤立（老年人或残疾人）个人的积极社会联系。

The proposed research will advance the state of the art in the area of computer systems supporting people to change their behaviour for their own benefit and for the benefit of the community. It will develop novel personalized persuasive technologies and incentive mechanisms that are trusted by users and that involve not just them, but their social circles (friends, neighbours, family members) in supporting them to achieve their behaviour change goals. I will explore effective motivational mechanisms empirically (through user studies and observations), theoretically (by designing trust and incentive mechanisms and evaluating them through theoretical analysis and simulations) and in practice (by designing and evaluating motivational mechanisms in real systems). I will use as a starting point selected theories of motivation and cognitive bias from social psychology to guide the design of persuasive strategies and incentive mechanisms that motivate users to engage in beneficial behaviours. The application areas include online shopping, self-improvement (learning), living a healthy lifestyle, practicing safe behaviours at work and leisure, and increasing the positive social connections of isolated (elderly or impaired) individuals.
