ICS 690 talk: Personal Environmental Trainer

  1. 1. The Personal Environmental Trainer Robert S. Brewer Presented to ICS 690 12/4/2008
  2. 2. Context <ul><li>My status </li></ul><ul><ul><li>Working on PhD research portfolio </li></ul></ul><ul><ul><li>In pre-proposal phase </li></ul></ul><ul><li>Presentation goals </li></ul><ul><ul><li>Spur myself to articulate proposal ideas </li></ul></ul><ul><ul><li>Share those ideas & related work </li></ul></ul><ul><ul><li>Get feedback </li></ul></ul>
  3. 3. The Problem <ul><li>Climate is changing and it’s our fault </li></ul><ul><ul><li>IPCC report 4 </li></ul></ul><ul><li>Need to reduce GHG emissions </li></ul><ul><ul><li>Switch to renewable energy sources </li></ul></ul><ul><ul><li>Many possible sources </li></ul></ul><ul><li>Reduced energy usage eases burden </li></ul><ul><ul><li>Increased efficiency </li></ul></ul><ul><ul><li>Behavior changes </li></ul></ul><ul><li>IT can play central role </li></ul><ul><ul><li>Provide awareness of energy usage </li></ul></ul><ul><ul><li>Support positive behavior changes </li></ul></ul>
  4. 4. Core Idea <ul><li>Make energy usage transparent </li></ul><ul><ul><li>At personal, neighborhood, and state levels </li></ul></ul><ul><li>Personal Environmental Tracker (PET) </li></ul><ul><ul><li>Gathers user activity data via sensors </li></ul></ul><ul><ul><li>Aggregate data in central depot </li></ul></ul><ul><ul><li>Present data & analyses to user </li></ul></ul><ul><li>Analyses and UI are the essence of PET </li></ul>
  5. 5. PET Background <ul><li>Energy usage feedback -> 10-15% reduction </li></ul><ul><ul><li>S. Darby 2006 for survey of many studies </li></ul></ul><ul><li>Carbon calculators provide estimates </li></ul><ul><ul><li>Broad estimates based on recollection </li></ul></ul><ul><ul><li>J. Murray & C. Dey 2007 for survey </li></ul></ul><ul><li>Systems for manually tracking footprint </li></ul><ul><ul><li>StepGreen , mobGAS </li></ul></ul><ul><li>Systems for tracking one aspect </li></ul><ul><ul><li>Ecorio , TED , Dopplr </li></ul></ul>
  6. 6. Two Directions <ul><li>Sensors and sensorbase provide the plumbing </li></ul><ul><li>Two ideas for UI focus </li></ul><ul><ul><li>1. Comprehensive carbon dashboard </li></ul></ul><ul><ul><li>2. Multi-level electricity feedback display </li></ul></ul>
  7. 7. 1: Dashboard Description <ul><li>Comprehensive, sensor-based carbon footprint </li></ul><ul><ul><li>Track electricity, ground transport, flights </li></ul></ul><ul><ul><li>Data from physical & informational sensors </li></ul></ul><ul><li>Integrated display allows rational decisions </li></ul><ul><ul><li>What areas should be prioritized </li></ul></ul><ul><li>Support behavior modification </li></ul><ul><ul><li>No one set of “best” modifications </li></ul></ul><ul><ul><li>Explore “what-if” scenarios </li></ul></ul><ul><li>Provide comparisons to other similar people </li></ul><ul><ul><li>Compare against friends, neighbors, averages </li></ul></ul>
  8. 8. Dashboard “Secret Sauce” <ul><li>Footprint based on data from diverse sources </li></ul><ul><ul><li>Other systems are either broad or use sensors, not both </li></ul></ul><ul><li>Explore what-if across sources of emissions </li></ul><ul><ul><li>How many long showers = cross Pacific airline flight </li></ul></ul><ul><li>Suggestions based on knowledge about user </li></ul><ul><ul><li>Sensor data can guide recommendations </li></ul></ul>
  9. 9. Dashboard Scenario <ul><li>Kimo starts using Dashboard </li></ul><ul><ul><li>Builds up data about daily activities </li></ul></ul><ul><li>Kimo feels guilty about taking long showers </li></ul><ul><ul><li>Electricity usage higher than neighbors </li></ul></ul><ul><ul><li>Dashboard suggests reducing hot water temp </li></ul></ul><ul><ul><li>Further option of solar hot water suggested </li></ul></ul><ul><li>But Kimo likes his showers hot </li></ul><ul><ul><li>Taking bus once a week = lots of showers </li></ul></ul><ul><ul><li>Kimo decides to take the bus on Fridays </li></ul></ul><ul><ul><li>After a few weeks, decides bus isn’t so bad </li></ul></ul><ul><ul><li>Kimo starts taking the bus every day </li></ul></ul>
  10. 10. Building Dashboard <ul><li>Leverage existing infrastructure </li></ul><ul><ul><li>Sensors: TED, GeoLife or Ecorio, Dopplr </li></ul></ul><ul><ul><li>Storage: Pachube , sensorbase.org </li></ul></ul><ul><li>Web app to display data & analyses </li></ul><ul><ul><li>Full functionality for display & interaction </li></ul></ul><ul><li>Social applications: Facebook, Twitter, Ning </li></ul><ul><ul><li>Display updates to self and friends </li></ul></ul><ul><ul><li>Others can be inspired by your choices </li></ul></ul><ul><ul><li>Use friends to build comparison list </li></ul></ul><ul><ul><li>Your commitments are public </li></ul></ul>
  11. 11. Evaluating Dashboard <ul><li>Physical sensors can be expensive </li></ul><ul><ul><li>Provide ways to enter estimates manually </li></ul></ul><ul><ul><li>Evaluate UI and utility of analysis </li></ul></ul><ul><li>Pilot study </li></ul><ul><ul><li>Test initial design, get feedback, eval again </li></ul></ul><ul><li>Small group of subjects get sensors </li></ul><ul><ul><li>Elicit baseline data from previous year </li></ul></ul><ul><ul><li>Equip subjects with sensors </li></ul></ul><ul><ul><li>Record data & provide consumption feedback </li></ul></ul><ul><ul><li>Survey subjects on their experiences </li></ul></ul><ul><ul><li>Track changes in carbon footprint </li></ul></ul>
  12. 12. 2: Electricity Feedback <ul><li>Electricity feedback can reduce usage </li></ul><ul><ul><li>Real-time feedback is best </li></ul></ul><ul><ul><li>Time-of-use rate awareness also helps </li></ul></ul><ul><li>Comparison with peers can also help </li></ul><ul><ul><li>Need to compare apples to apples </li></ul></ul><ul><ul><li>Don’t want to demotivate low consumers </li></ul></ul><ul><li>Utilities track generation & consumption </li></ul><ul><ul><li>Real time in CA during 2000 energy crisis </li></ul></ul><ul><ul><li>Bad news when demand exceeds supply </li></ul></ul>
  13. 13. Electricity Feedback “Secret Sauce” <ul><li>Put them all together </li></ul><ul><ul><li>Collect personal, community, and utility data </li></ul></ul><ul><ul><li>Combine together in one UI </li></ul></ul><ul><li>Does utility data help? </li></ul><ul><ul><li>Will users reduce load when utility is overloaded? </li></ul></ul>
  14. 14. Electricity Feedback Scenario <ul><li>Lani is running the dishwasher </li></ul><ul><ul><li>Notices the electricity meter shooting up </li></ul></ul><ul><ul><li>Heat drying dishes uses lots of juice </li></ul></ul><ul><ul><li>Decides to air dry dishes in the future </li></ul></ul><ul><li>Lani notices her daytime usage is > neighbors </li></ul><ul><ul><li>Looks for devices left on while she’s at work </li></ul></ul><ul><ul><li>Finds fan & air filter have been left on </li></ul></ul><ul><li>HECO heading into a crisis on hot windless eve </li></ul><ul><ul><li>Demand is high due to AC usage </li></ul></ul><ul><ul><li>Renewable energy from wind farm way down </li></ul></ul><ul><ul><li>Lani decides to open windows & reads a book </li></ul></ul>
  15. 15. Building Electricity Feedback <ul><li>Same data plumbing as Dashboard </li></ul><ul><li>Utility data harder </li></ul><ul><ul><li>Monthly trend reports available </li></ul></ul><ul><ul><li>Real-time data requires HECO participation </li></ul></ul><ul><ul><li>HECO planning time-of-use pricing </li></ul></ul><ul><li>Ambient display to make users aware </li></ul><ul><ul><li>LCD display in home? Chumby ? </li></ul></ul><ul><ul><li>Can provide “glanceable” display on cell phones </li></ul></ul>
  16. 16. Evaluating Electricity Feedback <ul><li>HECO participation = high risk </li></ul><ul><ul><li>Making data available benefits them </li></ul></ul><ul><ul><li>But if they cannot execute, then give up </li></ul></ul><ul><li>Recruit small group of subjects </li></ul><ul><ul><li>Install meters in homes </li></ul></ul><ul><ul><li>Record baseline usage </li></ul></ul><ul><ul><li>Install display showing only personal usage </li></ul></ul><ul><ul><li>Later add utility usage </li></ul></ul><ul><ul><li>Survey subjects on behavior changes </li></ul></ul><ul><ul><li>Track changes in electricity usage </li></ul></ul>
  17. 17. Common Issues <ul><li>Getting subjects & sensors is a pain </li></ul><ul><ul><li>But without them, what’s the point? </li></ul></ul><ul><li>Success shouldn’t lie solely on energy reduction </li></ul><ul><ul><li>Evaluate UI affordances separately </li></ul></ul><ul><li>IT also has environmental impact </li></ul><ul><ul><li>Ensure net reduction in energy </li></ul></ul><ul><li>Motivating behavior change </li></ul><ul><ul><li>Many systems provide awareness </li></ul></ul><ul><ul><li>Need to change awareness to action </li></ul></ul>
  18. 18. Mahalo <ul><li>Questions? </li></ul><ul><li>Comments? </li></ul><ul><li>Suggestions? </li></ul><ul><li>Interested in being a future subject?  </li></ul>
