Motivating Healthy Water Intake through Prompting, Historical Information, and Implicit Feedback
This addresses hydration behavior change for office workers, but it is incremental as it builds on existing behavior change techniques.
The researchers tackled the problem of motivating healthy water intake in work environments by developing Hydroprompt, a prototype that uses historical information, implicit feedback, and explicit prompting, and found it effective in a 3-week field deployment.
We describe Hydroprompt, a prototype for sensing and motivating healthy water intake in work environments. In a 3-week field deployment of Hydroprompt, we evaluate the effectiveness of three approaches to behavior change: historical information enabling users to compare their water intake lev- els across different times of day and days of week, implicit feedback providing subtle cues to users on the current hydration levels, and explicit prompting at- tempting to remind participants when hydration falls below acceptable levels or when substantial amount of time has elapsed since the last sip.
