is okay to go to sleep earlier at night. Design to trigger behavior: “Reverse alarm clock” in the form of a traffic light that goes off as a text/phone alarm and turns red at a preset time. Accumulate reward points in “energy bank” in the form of a car proportional to # of energy drinks/coffee not consumed that day. User can snooze if necessary, but lose points from the energy bank! An animal avatar in the car/energy bank gives user feedback . All reminders sent as text messages. Results from user testing (paper-prototype) Very cute idea, seems female oriented (animal, style of idea, etc) How to get people not to cheat? (# energy drinks not had, snooze) Outlet for points accumulated? Could be physical or virtual.
