  Results of UserTesting 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 Test results: Stanford University, Spring 2010 CS377v - Creating Health Habits habits.stanford.edu

  Shortcomings of DesignI may not always be next to my bag with carrots when receiving a phone call (when received calls while away from the bag, did not eat the carrot) May forget to eat a carrot in case of a long telephone conversation – additional trigger may be required (happened twice) May not work well when receiving many calls within short time frame (happened once) 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
