1. Principles of Smart Home Control Scott Davidoff, Min Kyung Lee, Charles Yiu, John Zimmerman, and Anind K. Dey Human-Computer Interaction Institute + School of Design Carnegie Mellon University Presented by, Sree Lekshmi (p2ELT13012) Sajana.A (p2ELT13015)

2. Outline Abstract Introduction Contribution Related works Field work summary Design principles conclusion

3. Abstract smart home researchers focused on the concept of control. Allow users to gain control over their lives activities and routines do not map well to programming tasks. End-user programming ultimately provides control of devices. suggest seven design principles that will help end-user programming systems deliver that control.

4. CAMP (Truong et al, 04) Micro Commander (Jahnke et al, 02)Speakeasy (Newman et al, 02) Jigsaw (Humble et al, 03) Focused on device control: visually, verbally  what you can do with the system; not what the system can do for..

5. Smart home control systems provide control of devices CURRENT RESEARCH Families are struggling to gain control of their lives Anthropological Perspective Technical Perspective How can smart home control systems help users regain control of their devices families lives

6. Families are struggling to gain control of their lives CURRENT RESEARCH Smart home control systems provide control of devices Anthropological PerspectiveTechnical Perspective How can smart home control systems help users regain control of their devices families lives

7. 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. 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 their children RELATED WORK BUSYNESS AS A MORAL GOOD

9. Busyness leads to stress Managing busyness is tough, if fails..A “house of cards” “The rush hour of life” Fear of the sick child RELATED WORK LESS THAN IDEAL CONTROL

10. RELATED WORK We could use this knowledge to develop tools that help families do less. Systems for family life control will have to co-exist with busyness IMPLICATIONS

11. 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. “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

13. FINDINGS “WICKED” PROBLEM OF ACTIVITY MANAGEMENT

30. Incremental precision Improvisation Technological infrastructure Lifestyle choices FINDINGS FLEXIBILITY AS A COPING STRATEGY

31. FINDINGS CONTROL AND FLEXIBILITY

32. FINDINGS ACTIVITIES CONSTRUCT FAMILY AND INDIVIDUAL IDENTITY Activities mean more than the work behind them People derive meaning from their participation

33. 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

34. 1:ALLOW FOR THE ORGANIC EVOLUTION OF ROUTINES AND PLANS Hard to specify a priori Incremental precision Many routines are “unremarkable”

35. 2:EASILY CONSTRUCT AND MODIFY PLANS AND ROUTINES Daily basis task planning and coordination Frequent interaction should merit attention Input should be low-cost

36. 3: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

37. 4:DESIGN FOR BREAKDOWNS Exceptions happen frequently Complete solution is impossible

38. 5:ACCOUNT FOR MULTIPLE, OVERLAPPING AND CONFLICTING GOALS More than one person May not agree on task performance metrics “Thermostat Predicament” Support v. Independence

39. 6: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”

40. 7:PARTICIPATE IN THE CONSTRUCTION OF FAMILY IDENTITY Some tasks are more than work They constitute how we interpret who we are

41. 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
