Transcript

  • 1. 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
  • 2. 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
  • 3. 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
  • 4. 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
  • 5. 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
  • 6. 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
  • 7. 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
    Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 8. Shortcomings of Design
      • I may not always be next to my bag with carrots when receiving a phone call
      • May forget to eat a carrot in case of a long telephone conversation – additional trigger may be required
      • May not work well when receiving many calls within short time frame
      • 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
  • 9. 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
  • 10. Next Steps in Design Process
      • Test concept on other users
      • Get user feedback
      • Iterate the prototype design
