Abstract：
This study was motivated by a desire to help working-age individuals gain a better understanding of their daily nutritional intakes with a new self-reported dietary assessment method because an unhealthy eating behavior increases the risks of developing chronic diseases. In this study, we present the design and evaluation of NutriColoring, a food diary that leverages doodling on sketches to report and reflect on everyday diet in the working context. Through a 2-week field study involving 18 participants, the usefulness of NutriColoring in facilitating dietary assessment was tested by making comparisons with the typical bullet diary method. Our quantitative results showed that NutriColoring provided users with improved dietary assessment experience and intrinsic motivations, with significantly low task frustration and high enjoyment. Because of the freedom and playfulness in reporting intakes at work, the interview findings showed a high acceptance of employing NutriColoring at work. This article is concluded with a set of implications for the design and development of a Doodling toolkit to support healthy eating behaviors among office workers.
摘要：
这项研究的动机是希望通过一种新的自我报告的饮食评估方法来帮助工作年龄的人更好地了解他们的日常营养摄入量，因为不健康的饮食行为会增加患慢性病的风险。在这项研究中,我们介绍了营养着色的设计和评估，一本食物日记，利用在草图上涂鸦来报告和反思工作环境中的日常饮食。通过为期2周的实地研究，包括18名参与者，通过与典型的子弹日记方法进行比较,检验了营养着色在促进饮食评估方面的有用性.我们的定量结果表明，营养着色为用户提供了改善的饮食评估经验和内在动机，具有显著低的任务挫败感和高的乐趣。由于在工作中报告摄入量的自由和嬉戏，访谈结果显示，在工作中使用NutriColoring的接受度很高。本文的结论是对设计和开发Doodling工具包以支持上班族健康饮食行为的一系列启示。
