  • Good solid work. . . . just keep going. What you'll learn in rolling out will be much better than any advice we can give at t his point.

  • - I really like your user choice. Niche, focused, motivated.
    - The idea seems interesting - uses medium the target group already uses (phones), and makes for an effective solution.
    - One thing I'd think about is how to make something like this dynamic. Just like a post-it loses importance once you've seen it 5 times, think about how you can keep the person motivated. Seeing the same text might make him get used to it.
    - One other wish is a way to track metrics - can you somehow ensure the person is actually doing what he's supposed to?

    - my hunch is that you should roll with this - see how it works out - you'll learn a ton!

Ultimate Sun v2 Presentation Transcript

  • 1. Ultimate Sun A conceptual design by Reed Matheny and Jimmy Chen Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu Design Challenge: To create a cycle behavior of sunscreen application in at least five people. Time limit: 4 hours
  • 2. Ultimate Sun
    • Persuasive Purpose
      • To influence one of the most sun-susceptible groups, Ultimate Frisbee players, to apply sunscreen regularly before all Frisbee events.
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
    • Industrial Design:
  • 3. User Description
      • Members of the Stanford Club Ultimate Frisbee Team who already understand the benefits of sunscreen but may forget to apply it before practice
      • Male students aged 18-25
      • Spend ~3 hours per practice outdoors, 2-3 times per week
      • Usually receive Ultimate-related information daily through email and/or text message
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 4. Ultimate Sun Storyboard Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu Ten minutes before practice, Matt receives a text: “Practice on Roble Field at 3:15pm. Don’t forget sunscreen!” Due to the immediacy of the reminder, Matt remembers to apply sunscreen. Matt clicks the link and is directed to a Google Form. The form describes the service, briefly outlines the benefits of sunscreen, and allows for easy signup. Matt fills in his cell phone number and cellular provider, then clicks Submit. Matt lives a long, healthy, melanoma-free life. Reminders are sent before each practice for the rest of the season. Matt receives an email about tomorrow’s ultimate frisbee practice. At the bottom of the email is a link to sign up for texts reminding him to go to practice and apply sunscreen.

  • 6. Features/Functionality
    • All members of the team list will see the email offering the Ultimate Sun service
    • Users enter their cell phone number and carrier information just once to receive reminders for all Frisbee events that are organized via email – reminders sent
    • Event reminders with sunscreen plug reach the user at the critical point – just before he is about to go outside and play (hot trigger)
    • Service automatically parses event time and location from email and renders them in the SMS reminder
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 7. Theoretical Justifications
    • Ultimate Sun takes advantage of both the high level of email communication among the Frisbee team and the immediacy of a text reminder just before playing
    • Frisbee events organized by email (practice, pickup, throwing) occur nearly everyday, making it the ideal technology to tap for this vulnerable group of athletes
    • It provides a friendly, lightweight reminder to a group of people who are aware of the benefits of sunscreen but frequently forget to bring their own sunscreen
    • This is primarily meant to be an intervention that helps users form a habit, but the service is agnostic about usage time – it can be easily extended to be an integration
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 8. Planned User Testing
      • After a trial period, text message those who signed up for the SMS reminders, asking them whether they actually applied sunscreen after the reminder – record results
      • Follow up by calling several users who did not apply sunscreen and ask them why
      • Send email to the entire list, asking those who did not sign up why they chose not to sign up
      • Do A/B testing on different text messages formats, including those with more health-related information
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 9. Shortcomings of Design
    • Not all players will feel the need to use text reminders for team events, neglecting the health aspects of the service
    • The reminder is not interactive: it’s only a short message before the event
    • There is a short time window to forget the sunscreen reminder. Often there is no perfect moment when the user is both carrying a cell phone and applying sunscreen on the field
    • This service is only a reminder – it assumes that the user has his own sunscreen and is willing to apply it
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 10. Expansion - What else is possible?
      • Other form factors or ID possibilities
        • Apply to other sports and outdoor activities that coordinate events via email
        • Supplement SMS with emails or Tweets
      • Other features and interactions
        • Include additional information about sunscreen as part of the SMS reminder (verify that this is effective through user testing)
        • Interactive self-report service: user submits a simple SMS reply to the reminder if he applies sunscreen and builds a reviewable data set of usage over time
        • Interactive self-report service: allow teammates to compare sunscreen usage frequency
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 11. Next Steps in Design Process
      • Create automated software system that parses emails and sends reminder texts
      • Conduct user testing to determine effectiveness of the service, iterating as needed
      • Include more features as outlined previously
      • Explore phone interfaces for channels other than SMS to distribute messages
