CRII: CHS: Examining a Multimodal Approach to Lowering the Burden of Food Journaling

人们使用个人日记的方法来培养更好的习惯，并对健康和福祉做出明智的决定。随着时间的推移，由于支持设备的设计不佳和单一平台的限制，食品日志等活动变得繁重，不准确或不完整。在这个项目中，研究人员计划使用物联网（IoT）功能来开发一个具有集成和多模式输入功能的系统，以支持食品日志。将开发一个集成设备平台，以支持来自智能手机、可穿戴设备和笔记本电脑等多种设备的数据输入。将采用迭代的、以用户为中心的设计方法。未来的用户将被选择进行可用性研究，原型将通过将多模式物联网食品日志与其他常见的食品日志应用进行比较来验证。好处包括更多可用的个人日志技术，以支持身心健康，压力管理和个人福祉。该项目将围绕两个参与式设计调查。研究小组（1）将研究有健康饮食目标的人如何使用轻量级技术探头，通过语音描述，摄影或文本描述记录食物。该探测器部署将为平台如何支持跨输入模态协作收集数据提供建议。这些建议，以及一个迭代的设计过程，以提高可用性，将告知一个功能齐全的多模态食品日志工具。然后，研究小组（2）将把开发的工具与商业和研究食品期刊的典型设计策略进行比较，同样是与有健康饮食目标的人进行比较。比较将是混合的方法，结合的价值和负担的技术，通过验证的调查工具与半结构化的访谈讨论每种方法的挑战的看法。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。

People use personal journaling methods to develop better habits and make informed decisions about health and well-being. Activities such as food journaling become burdensome, inaccurate, or incomplete over time due to poor design of supportive devices and single-platform constraints. In this project, the investigator plans to use internet-of-things (IoT) functionality to develop a system with integrated and multimodal input capabilities to support food journaling. An integrated device platform will be developed to support data input from multiple devices such as smart phones, wearables, and laptops. An iterative, user-centered design methodology will be applied. Prospective users will be selected for usability studies, and the prototype will be validated by comparing multimodal IoT-enabled food journaling to other common food journaling applications. Benefits include more usable technologies for personal journaling to support mental and physical health, stress management, and personal wellbeing. This project will center around two participatory design investigations. The research team (1) will examine how people with healthy eating goals use lightweight technology probes developed for journaling food via voice description, photography, or text description. This probe deployment will inform recommendations for how platforms can support collecting data collaboratively across input modalities. These recommendations, and an iterative design process to improve usability, will inform a full-featured multimodal food journaling tool. The research team (2) will then compare the developed tool against design strategies typical of commercial and research food journals, again with people who have healthy eating goals. The comparison will be mixed-methods, combining perceptions of the value and burden of the technology through validated survey instruments with semi-structured interviews discussing the challenges of each approach.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.
