    ICS 690 talk: Personal Environmental Trainer ICS 690 talk: Personal Environmental Trainer Presentation Transcript

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