Describes the UbiGreen project at the University of Washington (joint with CMU, Intel Labs, and Microsoft Research). The project attempts to use low-cost sensing, inference, and feedback to allow people to make better choices with respect to their use of precious resources. This project is an example of the larger thrust of activity-based ubiquitous computing. This was presented at the 3rd U.S.-China Computer Science Leadership Summit at Peking University, Beijing China on June 15, 2010.

Editor's Notes
- [20 minute goal, took 22 minutes, with a couple of questions along the way]
- Locke and Latham summarize 35 years of research into the effect of goals on behavior:Goals serve a directive function; they direct attention and effort toward goal-relevant activitiesGoals have an energizing function. Hard goals lead to greater effort than easy goals.Goals affect persistence. Hard goals prolong effort (LaPorte & Nath, 1976).I’ll talk more about how goals have been used to motivate environmental behavior with eco-feedback technology in the next part of the talk.
