Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home CURRENT RESEARCH CAMP (Truong et al, 04) microCommander (Jahnke et al, 02)Speakeasy (Newman et al, 02) Jigsaw (Humble et al, 03) DISCIPLINARY GAP Focused on device control: visually, verbally what you can do with the system; not what the system can do for..

7
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home CONTRIBUTIONS Recast the problem of smart home control Suggest new evaluation metrics for smart home control systems Provide rich description of nuanced notion of control Produce design principles to serve as signposts
8
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home Increased obligations of daily life Context switching across roles (home/work) A skill parents want to gracefully master Parents want to pass this skill on Darrah 2000, 2002 RELATED WORK BUSYNESS AS A MORAL GOOD
9
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home Busyness leads to stress Managing busyness is tough, if fails.. A “house of cards” “The rush hour of life” Fear of the sick child Beech 2004, Frissen 2000, Darrah 2002 RELATED WORK LESS THAN IDEAL CONTROL
10
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home Systems for family life control will have to co-exist with busyness RELATED WORK IMPLICATIONS
11
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home Goal: develop an opportunity map for technology to aid families 12 dual-income families Dual-income families: Large audience, representing 46% of the US population Lots of needs, early adopters FIELDWORK SUMMARY
12
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home “Wicked problem”* of activity management (= main source of family busyness) Flexibility as a coping strategy Relationship between control and flexibility Activities construct (individual/family) identity SUMMARY OF FINDINGS * Rittel 1973
13
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home FINDINGS “WICKED” PROBLEM OF ACTIVITY MANAGEMENT
14
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home EXAMPLE GAME OR PRACTICE? HOME OR AWAY? WHAT TIME?
15
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home EXAMPLE WHO PICKS UP? WHO DROPS OFF? WHERE?
16
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home EXAMPLE SHIN GUARDS, KNEE PADS. CLEATS OR FLATS?
17
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home EXAMPLE PRACTICE UNIFORM? HOME OR AWAY UNIFORM?
18
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home EXAMPLE CLEAN CLOTHES THE NIGHT BEFORE
19
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home EXAMPLE JUICE BEFORE OR AFTER? ORANGES AT HALFTIME?
20
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home EXAMPLE LOST ON THE CALENDAR
21
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home BREAKDOWNS LAST MINUTE CARPOOL DECISIONS

25
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home BREAKDOWNS CREEPING RESPONSIBILITY
26
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home BREAKDOWNS CREEPING RESPONSIBILITY
27
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home BREAKDOWNS UNPREDICTABLE ORANGES
28
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home BREAKDOWNS SICK CHILD
29
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home BREAKDOWNS CASCADE EFFECTS
30
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home Incremental precision Improvisation Technological infrastructure Lifestyle choices FINDINGS FLEXIBILITY AS A COPING STRATEGY
31
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home FINDINGS CONTROL AND FLEXIBILITY
32
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home FINDINGS ACTIVITIES CONSTRUCT FAMILY AND INDIVIDUAL IDENTITY Activities mean more than the work behind them People derive meaning from their participation
33
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home Now what? RELATED WORK
34
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home SEVEN DESIGN PRINCIPLES Allow for the organic evolution of routines and plans Participate in the construction of family identity The home is more than a location Understand periodic changes, exceptions and improvisation Design for breakdowns Easily construct new plans and routines, and modify existing ones Account for multiple, overlapping and occasionally conflicting goals
35
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home PRINCIPLE 1:ALLOW FOR THE ORGANIC EVOLUTION OF ROUTINES AND PLANS Hard to specify a priori Incremental precision Many routines are “unremarkable” * Tolmie 2002
36
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home PRINCIPLE 2:PARTICIPATE IN THE CONSTRUCTION OF FAMILY IDENTITY Some tasks are more than work They constitute how we interpret who we are
37
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home PRINCIPLE 3:THE HOME IS MORE THAN A LOCATION Opportunistic planning occurs in many locations A smart home is more than a physical space Also includes “information space”
38
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home PRINCIPLE 4:UNDERSTAND PERIODIC CHANGES, EXCEPTIONS AND IMPROV Routines are often not routine Vary by season Routines change with exceptions Rigid model of routines would not fit observation
39
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home PRINCIPLE 5:DESIGN FOR BREAKDOWNS Exceptions happen frequently Complete solution is impossible
40
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home PRINCIPLE 6:EASILY CONSTRUCT AND MODIFY PLANS AND ROUTINES Daily basis task planning and coordination Frequent interaction should merit attention Input should be low-cost
41
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home 7:ACCOUNT FOR MULTIPLE, OVERLAPPING AND CONFLICTING GOALS More than one person May not agree on task performance metrics “Thermostat Predicament” Support v. Independence PRINCIPLE
42
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon Family Control Smart Home CONCLUSIONS Family is a place of busyness where identity and life control collide Opportunity for technology to improve quality of family life Design principles help address this space Evaluate smart home technology in terms of life control
