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 <ul><li>Persuasive Purpose </li></ul><ul><ul><li>To eat one peeled carrot each time I receive a phone call. </li></ul></ul>Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu <ul><li>Industrial Design </li></ul>
  • 3. User Description <ul><ul><li>Typical PhD student who doesn’t take the time to eat, not to mention eat healthy </li></ul></ul><ul><ul><li>This typical user is…myself </li></ul></ul>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 <ul><ul><li>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 </li></ul></ul><ul><ul><li>Image can be updated periodically to bring more fun into the process and develop new alertness </li></ul></ul>Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 6. Theoretical Justifications <ul><ul><li>Health incentive (snacking is good as it reduces the amount of food consumed at one time; snacking healthy is even better) </li></ul></ul><ul><ul><li>Research shows that carrots can improve the appearance of the skin, hair and nails </li></ul></ul><ul><ul><li>If taken daily carrots can lower cholesterol and blood pressure </li></ul></ul><ul><ul><li>If eaten raw, carrots contains beta-carotene, a strong antioxidant that can prevent cancer </li></ul></ul><ul><ul><li>Carrots can regulate blood sugar </li></ul></ul><ul><ul><li>Carrots are rich in fiber and can promote colon health </li></ul></ul>Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 7. Results of User Testing <ul><ul><li>I happened to love carrots and was surprised to have enjoyed carrying a bag of carrots in my backpack and snacking throughout the day </li></ul></ul><ul><ul><li>On the first day I realized that one full bag cannot be consumed in one day </li></ul></ul><ul><ul><li>Switched to ziploc bag with only 10 carrots </li></ul></ul>Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 8. Shortcomings of Design <ul><ul><li>I may not always be next to my bag with carrots when receiving a phone call </li></ul></ul><ul><ul><li>May forget to eat a carrot in case of a long telephone conversation – additional trigger may be required </li></ul></ul><ul><ul><li>May not work well when receiving many calls within short time frame </li></ul></ul><ul><ul><li>Have to stop if I ride my bike and receive a call </li></ul></ul><ul><ul><li>Carrots can go bad if kept in the backpack in a hot day </li></ul></ul>Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 9. Expansion - What else is possible? <ul><ul><li>Other form factors or ID possibilities </li></ul></ul><ul><ul><ul><li>Can be scaled to other activities (i.e. each time an email is received the system pops up an image of a carrot) </li></ul></ul></ul><ul><ul><li>Other features and interactions </li></ul></ul><ul><ul><ul><li>Automate changing the picture ID trigger by leveraging existing resources (i.e. Flickr database of photos) </li></ul></ul></ul>Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
  • 10. Next Steps in Design Process <ul><ul><li>Test concept on other users </li></ul></ul><ul><ul><li>Get user feedback </li></ul></ul><ul><ul><li>Iterate the prototype design </li></ul></ul>Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu
