CAREER: Transforming Personal Informatics Systems to Support Routine Transitions in Healthy Eating

许多人使用智能手表和移动跟踪应用程序等个人信息技术来支持和维护他们的健康饮食目标。然而，日常生活的中断和转变，如搬家、工作变动或家庭疾病，可能会干扰他们坚持目标的能力。当这些转变发生时，它们可能会影响个人获取健康饮食资源的方式，或者给人们带来挑战，让他们在既定的常规之外保持健康的饮食行为。转变还可能创造新的需求，或改变人们围绕健康饮食的优先事项。然而，当前的个人信息学技术通常是基于日常行为保持静态的假设而设计的。因此，当日常生活发生转变时，现有技术难以帮助人们评估和适应不断变化的需求、约束和优先事项。因此，这个项目的目的是研究如何设计个人信息学系统，以支持人们在个人和合作的日常生活中经历转变时的健康饮食。最初的工作将是系统地了解人们的需求，以及当他们的日常生活发生转变时健康饮食的挑战。这些发现将有助于创建支持围绕这些过渡进行技术设计的设计原则和理论基础。第二条线将迭代地设计和开发能够支持人们应对过渡并继续健康饮食的技术。最后，项目团队将进行实地研究，以评估随着时间的推移和在过渡环境中使用这些技术的有用性、可用性和参与度。该项目将提供经验知识、设计指南、理论框架和现场评估的技术，以支持日常生活中的健康饮食过渡。它还包括针对大学、高中和当地社区的综合教育和外展活动。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Many people use personal informatics technology, such as smartwatches and mobile tracking applications, to support and maintain their healthy eating goals. However, disruptions and transitions of routines, such as moving, job changes, or family illness, can interfere with their ability to stick to their goals. When these transitions happen, they might influence how individuals access healthy eating resources or create challenges for people to maintain their healthy eating behavior outside their established routine. Transitions may also create new needs or change people’s priorities around healthy eating. However, current personal informatics technology is typically designed based on the assumption that everyday behavior remains static. As a result, when transitions happen in everyday life, existing technologies struggle to help people assess and adapt to the changing needs, constraints, and priorities. Thus, this project aims to examine how personal informatics systems can be designed to support people in healthy eating when experiencing transitions in their routines, individually and collaboratively. The initial line of work will be to systematically understand people’s needs and the challenges of healthy eating when transitions in their routines occur. These findings will help create design principles and theoretical foundations supporting technology design around these transitions. The second line of work will iteratively design and develop technologies that can support people to cope with transitions and continue to eat healthily. Finally, the project team will conduct field studies to evaluate the usefulness, usability, and engagement with these technologies over time and in the context of transitions. The project will contribute empirical knowledge, design guidelines, theoretical frameworks, and field-evaluated technology to support healthy eating during transitions in routines. It also includes integrated education and outreach activities for universities, high schools, and local communities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
