Interactive systems that aim to motivate people to adopt behaviours and actions that are beneficial for them and their community are attracting the attention of governments, practitioners, and researchers. Persuasive Technologies (PTs) are interactive systems designed to motivate desirable behaviour change. Despite the growing interest and investments into PTs, current PT design frameworks suffer a major limitation: They are based on the one-size-fits-all approach and hence resulting PTs are not personalized to be appropriate for the target user(s). Personalization in persuasive technologies is challenging, since motivating users for a particular behaviour or action needs to take into account a wide range of individual and context-dependent factors. The primary objective of this research is to develop, evaluate, and refine novel multi-dimensional mechanisms (that considers multiple factors simultaneously) for personalizing and adapting persuasive technologies to make them appropriate for individual users and increase their efficacy at promoting positive behaviour. First, we will develop multidimensional personalization models of user's responses to distinct persuasive strategies using both explicit and implicit user behaviour data gathered via user studies, using interaction log, and physiological responses across various behaviour contexts. Second, to evaluate the efficacy of the models across various persuasion contexts, we will apply the models to design, develop, and evaluate new model-driven personalized and adaptive persuasive systems targeting three technical domains (digital games, mobile, and social computing) and two application areas (health/wellness and safety/security). The persuasive systems will be targeted at diverse audience including at-risk and underserved Canadian populations: African Nova Scotians and Aboriginals, older adults, and youths.The primary outcomes of this research will be: 1) The development of novel multi-dimensional mechanisms for personalizing and adapting persuasive systems, and 2) applications of these mechanisms in designing and evaluating several personalized persuasive systems that motivate and assist users towards beneficial behaviours. Overall, successful completion of this research will lead to technological advances in the area of adaptive systems design. Our innovations have the potential for economic benefits within the Canadian computer games industry, to inform better game designs. Finally, our work inscribes in the broader framework of adaptive and intelligent systems for social good: it can improve the lives of Canadians by targeting several problem domains (including safety/security and health/wellness). This work can help everyone, but can also target specific, at-risk Canadians and under-served populations (e.g., African Nova Scotians, Aboriginals, older adults).

旨在激励人们采取对他们及其社区有益的行为和行动的互动系统正在吸引政府、从业者和研究人员的关注。说服性技术 (PT) 是一种交互式系统，旨在激发理想的行为改变。尽管人们对 PT 的兴趣和投资不断增长，但当前的 PT 设计框架面临着一个主要限制：它们基于一刀切的方法，因此生成的 PT 并未个性化以适合目标用户。说服性技术中的个性化具有挑战性，因为激励用户进行特定的行为或行动需要考虑广泛的个人和上下文相关因素。这项研究的主要目标是开发、评估和完善新颖的多维机制（同时考虑多个因素），以个性化和调整说服技术，使其适合个人用户并提高其促进积极行为的功效。首先，我们将使用通过用户研究收集的显式和隐式用户行为数据、使用交互日志和跨各种行为环境的生理反应，开发用户对不同说服策略的反应的多维个性化模型。其次，为了评估模型在各种说服环境中的有效性，我们将应用这些模型来设计、开发和评估新的模型驱动的个性化和自适应说服系统，针对三个技术领域（数字游戏、移动和社交计算）和两个应用领域（健康/保健和安全/保障）。说服系统将针对不同的受众，包括高危和服务不足的加拿大人群：非洲新斯科舍人和原住民、老年人和青少年。这项研究的主要成果将是：1）开发用于个性化和适应说服系统的新颖的多维机制，2）应用这些机制来设计和评估几种激励和协助的个性化说服系统 用户采取有益的行为。总的来说，这项研究的成功完成将带来自适应系统设计领域的技术进步。我们的创新有可能为加拿大电脑游戏行业带来经济效益，为更好的游戏设计提供信息。最后，我们的工作铭刻在更广泛的适应性和智能系统框架中，以实现社会公益：它可以通过针对多个问题领域（包括安全/安保和健康/保健）来改善加拿大人的生活。这项工作可以帮助每个人，但也可以针对特定的高危加拿大人和服务不足的人群（例如非洲新斯科舍人、原住民、老年人）。
