  • Can't eat a full bag b/c you don't get enough phone calls?

    I ate most of a bag today, I think. Along with snap peas. Too much, really.

    --

    But my big question: The goal is to get 5 people to start increasing their habit. This seems to be just for you. Rationale?

    • I has a karot A conceptual design by Victor Gane Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu Design Challenge To . . . eat a peeled carrot each time I receive a phone call. Time limit: 3 days
    • I has a karot
      • Persuasive Purpose
        • To eat one peeled carrot each time I receive a phone call.
      Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
      • Industrial Design
    • User Description
        • Typical PhD student who doesn’t take the time to eat, not to mention eat healthy
        • This typical user is…myself
      Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
    • I has a karot storyboard Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu Instead of the photo of the person calling I see the trigger reminding me to eat a carrot During the call or shortly after I reach for my backpack and grab a carrot I change the picture caller id to act as a trigger to eat a carrot when I receive any phone call Every morning before leaving to school I put a bag of peeled carrots in my backpack I receive the first phone call and check who is calling I feel less desire to eat large meals after snacking on carrots 4-6 times a day
    • Features/Functionality
        • Any smart phone can be customized with a picture ID call image reminding the user to eat one baby carrot each time he/she receives a phone call
        • Image can be updated periodically to bring more fun into the process and develop new alertness
      Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
    • Theoretical Justifications
        • Health incentive (snacking is good as it reduces the amount of food consumed at one time; snacking healthy is even better)
        • Research shows that carrots can improve the appearance of the skin, hair and nails
        • If taken daily carrots can lower cholesterol and blood pressure
        • If eaten raw, carrots contains beta-carotene, a strong antioxidant that can prevent cancer
        • Carrots can regulate blood sugar
        • Carrots are rich in fiber and can promote colon health
      Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
    • Results of User Testing
        • I happened to love carrots and was surprised to have enjoyed carrying a bag of carrots in my backpack and snacking throughout the day
        • On the first day I realized that one full bag cannot be consumed in one day
        • Switched to ziploc bag with only 10 carrots
        • Test results:
      Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
    • Shortcomings of Design
        • I may not always be next to my bag with carrots when receiving a phone call (when received calls while away from the bag, did not eat the carrot)
        • May forget to eat a carrot in case of a long telephone conversation – additional trigger may be required (happened twice)
        • May not work well when receiving many calls within short time frame (happened once)
        • Have to stop if I ride my bike and receive a call
        • Carrots can go bad if kept in the backpack in a hot day
      Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
    • Expansion - What else is possible?
        • Other form factors or ID possibilities
          • Can be scaled to other activities (i.e. each time an email is received the system pops up an image of a carrot)
        • Other features and interactions
          • Automate changing the picture ID trigger by leveraging existing resources (i.e. Flickr database of photos)
      Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
    • Next Steps in Design Process
        • Test concept on other users
        • Get user feedback
        • Iterate the prototype design
