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.

Focused on device control: visually, verbally what you can do with the system; not what the system can do for..

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

• 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 WORKBUSYNESS AS A MORAL GOOD

• 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

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

• “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

FINDINGS “WICKED” PROBLEM OF ACTIVITY MANAGEMENT

EXAMPLE GAME OR PRACTICE? HOME OR AWAY? WHAT TIME?

EXAMPLE WHO PICKS UP? WHO DROPS OFF? WHERE?

EXAMPLE SHIN GUARDS, KNEE PADS. CLEATS OR FLATS?

EXAMPLE PRACTICE UNIFORM? HOME OR AWAY UNIFORM?

EXAMPLE CLEAN CLOTHES THE NIGHT BEFORE

EXAMPLE JUICE BEFORE OR AFTER? ORANGES AT HALFTIME?

Incremental precision

Improvisation

Technological infrastructure

Lifestyle choices

FINDINGS FLEXIBILITY AS A COPING STRATEGY

FINDINGS CONTROL AND FLEXIBILITY

FINDINGSACTIVITIES CONSTRUCT FAMILY AND INDIVIDUAL IDENTITY

Activities mean more than the work behind

them

People derive meaning from their

participation

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

1:ALLOW FOR THE ORGANIC EVOLUTION OF ROUTINES AND PLANS

Hard to specify a priori

Incremental precision

Many routines are “unremarkable”

2:EASILY CONSTRUCT AND MODIFY PLANS AND ROUTINES

Daily basis task planning and

coordination

Frequent interaction should merit

attention

Input should be low-cost

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

4:DESIGN FOR BREAKDOWNS

Exceptions happen frequently

Complete solution is impossible

5:ACCOUNT FOR MULTIPLE, OVERLAPPING AND CONFLICTING GOALS

More than one person

May not agree on task performance

metrics

“Thermostat Predicament”

Support v. Independence

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”

7:PARTICIPATE IN THE CONSTRUCTION OF FAMILY IDENTITY

Some tasks are more than work

They constitute how we interpret who

we are

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
