The document proposes a system called "Weather or Not" that sends text messages to resident advisors (RAs) and peer health educators (PHEs) at Stanford to encourage sunscreen and vitamin D usage. The system would track local weather and randomly send texts on sunny days reminding RAs to suggest residents use sunscreen, and on rainy days remind them about vitamin D. The goal is to promote health habits among dorm residents by making recommendations unexpected and gamified. It discusses the design, theoretical justifications, shortcomings, and possibilities for expansion.

4. Weather or Not Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu The text message will tell her about the weather in local terms (it's super sunny on Wilbur field!) and have a bit.ly link to let her e-mail her residents On an especially dreary/rainy day, the system may (or may not) remind her to provide Vitamin D to her residents, and to make things really random... Grace wants to be a helpful RA and PHE but she's inside studying all the time Fortunately, she has signed up for the "Weather or Not" service on her cell phone, that works a little like a slot machine When it is an especially sunny day, the system will text message Grace in the afternoon at some unpredictable time reminding her to suggest sunscreen to her "kids" At most once a quarter, the system will pick one RA, and have the other RAs "bomb" them with excessive sunscreen after fountain hopping
