Fun in the Sun

Persuasive Purpose To encourage users to put on sunscreen before engaging in

outdoors activities

User Description

• Business school students who have signed up on the “SchwabSports Mailing List,” indicating interest in participating in pickup basketball, soccer, volleyball, and other games at the Manzanita fields

• They are likely…• 22-32 years old• Active• Well-educated about

the benefits of sunscreen• Very frequent users

of cell phones

John Smith Goes to Manzanita

Using the pocket-sized sunscreen that is in his backpack, John goes to the bathroom to apply the sunscreen to his face after class and texted back: “Yes, I just did!”

Later on at lunch time, John got an email from the SchwabSport list that said:” Anyone up for pickup soccer in 15 minutes?”

John wakes up on a beautiful spring day in California

He goes to class while daydreaming about spending the day outside

Between his first and second class, John gets a text message: “Have you put on your sunscreen today?”

John rushed back to his room and managed to be out on the field in 10 minutes, completely protected from the sun!

Prototype of Fun in the Sun

• The user will get a reminder in the morning and during class break times (7:45am, 9:45am & 11:45am) to apply sunscreen

• If the user has not put on sunscreen in the morning, then the user will use the pocket-sized sunscreen (distributed) for the daily application

Stanford University, Spring 2010CS377v - Creating Health Habitshabits.stanford.edu

Features/Functionality

• The mobile application is a simple trigger which reminds the user to apply sunscreen daily

• The reminder is phrased in a question-form so that the user can respond and confirm that he/she has applied sunscreen each day

• The pocket-sized sunscreen helps with the user’s ability so that the trigger does not have to be as precise (e.g. after the user wakes up and before he/she leaves the room for morning classes)

Stanford University, Spring 2010CS377v - Creating Health Habitshabits.stanford.edu

Theoretical Justifications

• Persuasive Strategies• Personalized – each user gets his/her own text

message• Response-Prompting

• Users are much more likely to apply sunscreen if they have to confirm back that they have done so

• Tracking• The response allowed the user result to be tracked

more accurately than simply relying on the users’ memory

• Targeted Users• Targeted users are more likely to spend a substantial

amount of time in the sun, thereby providing greater motivation

Results of User Testing

• To Be Updated

Stanford University, Spring 2010CS377v - Creating Health Habitshabits.stanford.edu

Shortcomings of Design

• Although the pocket-sized sunscreen helps facilitate the trigger, it is possible that the trigger may come at an inconvenient time (particularly Wednesdays and the weekends)

• The design is likely only effective for a definitive period of time and is reliant on the user maintaining the habit post the trial period

Expansion - What else is possible?

• Other features and interactionso Use the reminder tool to encourage other health habits

(flossing, drinking more water, etc)

Next Steps in Design Process

• Expand text messages to include other facts that may more persuasively motivate users to put on sunscreen• For example, facts showing greater aging without

sunscreen usage
