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.

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
![Page 8: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/8.jpg)
• 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
![Page 9: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/9.jpg)
• 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
![Page 10: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/10.jpg)
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

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
![Page 12: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/12.jpg)
• “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

FINDINGSACTIVITIES CONSTRUCT FAMILY AND INDIVIDUAL IDENTITY
Activities mean more than the work behind
them
People derive meaning from their
participation
![Page 33: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/33.jpg)
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
![Page 34: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/34.jpg)
1:ALLOW FOR THE ORGANIC EVOLUTION OF ROUTINES AND PLANS
Hard to specify a priori
Incremental precision
Many routines are “unremarkable”
![Page 35: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/35.jpg)
2:EASILY CONSTRUCT AND MODIFY PLANS AND ROUTINES
Daily basis task planning and
coordination
Frequent interaction should merit
attention
Input should be low-cost
![Page 36: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/36.jpg)
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
![Page 37: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/37.jpg)
4:DESIGN FOR BREAKDOWNS
Exceptions happen frequently
Complete solution is impossible
![Page 38: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/38.jpg)
5:ACCOUNT FOR MULTIPLE, OVERLAPPING AND CONFLICTING GOALS
More than one person
May not agree on task performance
metrics
“Thermostat Predicament”
Support v. Independence
![Page 39: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/39.jpg)
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”
![Page 40: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/40.jpg)
7:PARTICIPATE IN THE CONSTRUCTION OF FAMILY IDENTITY
Some tasks are more than work
They constitute how we interpret who
we are
![Page 41: Principles of Smart Home Control](https://reader035.fdocuments.in/reader035/viewer/2022062811/56815f62550346895dce4d63/html5/thumbnails/41.jpg)
CONCLUSIONSFamily 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
