Veggie Alarm Veggie Alarm Presentation Transcript

  • Veggie Alarm A conceptual design by Andrew Hershberger Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu Design Challenge Use mobile or social technology to influence at least five college students to create a stronger habit of eating vegetables every day.
  • Veggie Alarm
    • Persuasive Purpose
      • Use mobile or social technology to
      • influence at least five college
      • students to create a stronger habit
      • of eating vegetables every day.

  • User Description
      • Users are Stanford graduate students who:
        • Want to eat more vegetables
        • Live in Escondido Village
        • Buy their own groceries
        • Carry a cell phone with a repeating alarm feature
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • Time For A Snack Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu Todd decides to set his cell phone alarm for 7 PM. He usually stays in the lab until six, so he should definitely be home by seven. The next day, Todd’s alarm goes off at 7 PM. Todd is a Stanford student. He used to be in great shape, but recently he’s been working so much that when he’s hungry, he just reaches for the potato chips – “there’s just no time to decide what else to eat,” he says. One of Todd’s friends invites him to try out a new way to increase the number of vegetables he eats every day. It’s called Veggie Alarm, and all Todd has to do is set a repeating alarm on his cell phone. Before he gets started, Todd also has to think of one raw vegetable he likes and buy some at the store. He picks baby carrots. They’re just so easy and so delicious. Todd is thankful that he doesn’t have to decide what to eat for an appetizer tonight. He goes straight for the carrots. 6:30, biking home

  • Features/Functionality
      • Users set a repeating alarm on their cell phone
      • The suggested time for the alarm is 30 minutes after they usually arrive home from the lab
      • Users also need to pick a vegetable they enjoy eating raw and have a supply on hand at home
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • Theoretical Justifications
      • Simplicity
        • The repeating alarm only needs to be set once.
        • Users only have to eat one vegetable for the snack (although it is okay to eat more too).
      • Timing
        • The trigger (the alarm) comes in the evening when the user is at home and vegetables are available for a snack.
        • Since the user picks the time for the alarm, it could work for people with different schedules or in different time zones.

  • Plans for User Testing
      • Recruit friends via Facebook to participate for five days.
      • Sell it as an “experiment.”
      • Explain and demonstrate how to do it with a video.
      • Surveys to gather data
        • Entrance survey
        • Daily during the trial
        • Wrap-up a few days after required participation is over
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • Shortcomings of Design
      • Users might not always get home at the same time, so repeating alarms may turn into cold triggers if no veggies are available.
      • Alarm could conflict with dinner time since both are in the evening.
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • Expansion - What else is possible?
      • Other features and interactions
        • Use a calendar (e.g. Google Calendar, etc.) to send reminders, or generate alarms at different times each day
        • Turn it into a service that automatically analyzes your calendar to pick good times to remind you to eat veggies
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • Next Steps in Design Process
      • Shaping
        • Eat more than one veggie at the alarm time.
        • Add another alarm time
      • Scaling
        • Expand to another audience (e.g. families who could participate as a group)
