Our multi-disciplinary team is developing mobile computing software that uses "just-in-time" presentation of information to motivate behavior change. Using a participatory design process, preliminary interviews have helped us to establish 10 design goals. We have employed some to create a prototype of a tool that encourages better dietary decision making through incremental, just-in-time motivation at the point of purchase.
