Can a computer help you quit smoking, watch less TV, or improve your eating habits? Researchers are studying how people interact with their devices — and how "persuasive technologies" might help us stay on track.
Such devices could be as simple as a pillbox that reminds a patient to take medication, or as complicated as the design of computer applications that encourage users to return to a Web site and interact with it.
