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
