3. User Description

I has a karotstoryboard Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu Instead of the photo of the personcalling 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 callEvery 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

    • Health incentive (snacking is good as it reduces the amount of food consumed at one time; snacking healthy is even better)
    • Research shows thatcarrots 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

    • 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

    • 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)

    • Test concept on other users
    • Get user feedback
    • Iterate the prototype design
