User Description

• Typical PhD student who doesn’t take the time to eat, not to mention eat healthy

• This typical user is…myself

I has a karot I has a karot storyboard

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

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

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

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

Expansion - What else is possible?

• Other form factors or ID possibilitieso 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 interactionso Automate changing the picture ID trigger by leveraging

existing resources (i.e. Flickr database of photos)
