人工食物日志和自动饮食监测(ADM)各自的优缺点表明,结合这两种方法的半自动日志系统具有价值。然而,目前对人们如何预测实现半自动食物日志系统的策略的理解是有限的。因此,我们进行了一项有600个回答的投机性调查研究,研究人们如何预测自动捕获和提示细节的方法。参与者认为ADM传感器的位置和检测能力会影响预期的物理、社会和隐私负担。人们更积极地期待包含与他们的日记目标相关的信息的提示,帮助他们回忆起他们吃了什么,并迅速做出反应。我们的工作表明,在ADM系统的检测性能和预期可接受性之间需要权衡,面部区域的传感器比其他区域的传感器性能更高,但可接受性较低,而更有用的提示方法(如含有特定食物的提示方法)比手动提醒更具挑战性。我们建议有机会改进高可接受性、低精度的ADM传感器,选择基于个人和从业者日志需求的方法,并更好地向潜在用户描述能力。
The respective benefits and drawbacks of manual food journaling and automated dietary monitoring (ADM) suggest the value of semi-automated journaling systems combining the approaches. However, the current understanding of how people anticipate strategies for implementing semi-automated food journaling systems is limited. We therefore conduct a speculative survey study with 600 responses, examining how people anticipate approaches to automatic capture and prompting for details. Participants feel the location and detection capability of ADM sensors influences anticipated physical, social, and privacy burdens. People more positively anticipate prompts which contain information relevant to their journaling goals, help them recall what they ate, and are quick to respond to. Our work suggests a tradeoff between ADM systems' detection performance and anticipated acceptability, with sensors on facial areas having higher performance but lower acceptability than sensors in other areas and more usable prompting methods like those containing specific foods being more challenging to produce than manual reminders. We suggest opportunities to improve higher-acceptability, lower-accuracy ADM sensors, select approaches based on individual and practitioner journaling needs, and better describe capabilities to potential users.
