Safe Ears
Persuasive Purpose To influence users to adopt the
health habit of applying sunscreen by helping them achieve the smallest behavior that matters of application to the ears every morning.

User Description
• Busy students who regularly eat lunch outside of the Packard building.
• They are probably graduate students who work in Packard or Gates.
• They spend most of the day indoors, so they don't think to apply sunscreen.

Storyboard: Daniel at Work
He grabs his sunscreen from his bag and applies it.
Daniel is a busy grad student who spends most of his time coding for his exciting research project.
He notices that he's received a text message, and decides to check it.
It's that new service he signed up for to help him remember to protect his ears before eating lunch outdoors with his friends.
As he eats lunch outside, Daniel rests easy, knowing his ears are safe from the sun.

Prototype of Safe Ears
11 AM
Stanford University, Spring 2010CS377v - Creating Health Habitshabits.stanford.edu
Features/Functionality
• Users get a text at 11 AM every day so their sunscreen is applied before they go to lunch.
• Sunscreen bottle is carried in backpack in a plastic ziplock bag to prevent spilling.

Theoretical Justifications
• Ears are especially sensitive to burning• Sunscreen is only effective for a few hours.• Fogg Behavior Model:
o Motivation - known benefits of using sunscreen
o Simplicity - availability of sunscreen, quick to apply to ears
o Trigger - daily text message just before peak exposure hours

Results of User Testing
• Plan to user test with online surveys multiple times per week, with entry and exit surveys as well.

Shortcomings of Design
• Sunscreen makes hands slimy, so users need to wash them
• The texts could interrupt users' work• Small coverage area (only ears)

Expansion - What else is possible?
• Customizable text delivery times• Allow response to text to indicate that the
behavior was performed• Track stats, allow Facebook sync to enable
competition

Next Steps in Design Process
• Find users, run a pilot study.• Get feedback to inform iteration.
