Personalized and Trusted Behaviour Change Technologies

这项拟议的研究将推动计算机系统领域的最先进水平，支持人们为了自己的利益和社区的利益而改变自己的行为。它将开发新的个性化说服技术和激励机制，这些技术和激励机制得到用户的信任，不仅让他们，而且让他们的社交圈(朋友、邻居、家人)参与支持他们实现行为改变目标。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(通过设计和评估真实系统中的激励机制)来探索有效的激励机制。我将使用社会心理学中关于动机和认知偏差的精选理论作为起点，来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、在工作和休闲时实践安全行为，以及增加孤立(老年人或受损)个人的积极社会关系。

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.
