4. A sunny day in California Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu Two college students Clair and Chloe sign in the ZipSunscreen independently, and are assigned to a group of five who are living and studying in the neighborhood. They follow twitter of ZipSunscreen and other members. Chloe finishes the morning class. The sky cleared up and she realizes she forgot to put sunscreen today but does not bring one. Clair brings sunscreen, but is not aware she needs to use one today. Clair notices ZipSunscreen tweet and is reminded of having a sunscreen with her. She puts sunscreen and tweet her location. Chloe notices ZipSunscreen tweets and knows that Clair has sunscreen nearby. Chloe drops by the Arbuckle Café and share the sunscreen with Clair. On the other day, Clair forgets to bring sunscreen, while Chloe brings one with her. Through the same process, this time Clair drops by Old Union and shares sunscreen with Chloe.
