Description

Seeking to be sensitive to users, smart home researchers have focused on the concept of control. They attempt to allow users to gain control over their lives by framing the problem as one of end-user programming. But families are not users as we typically conceive them, and a large body of ethnographic research shows how their activities and routines do not map well to programming tasks. End-user programming ultimately provides control of devices. But families want more control of their lives. In this paper, we explore this disconnect. Using grounded contextual fieldwork with dual-income families, we describe the control that families want, and suggest seven design principles that will help end-user programming systems deliver that control. By Scott Davidoff, Min Kyung Lee, Charles Yiu, John Zimmerman + Anind K. Dey.

“ Wicked problem” of activity management Flexibility as a coping strategy Relationship between control and flexibility Activities construct identity SUMMARY OF FINDINGS * Rittel 1973

“ Wicked problem” of activity management

Flexibility as a coping strategy

Relationship between control and flexibility

Activities construct identity

EXAMPLE SHIN GUARDS, KNEE PADS. CLEATS OR FLATS?

EXAMPLE PRACTICE UNIFORM? HOME OR AWAY UNIFORM?

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

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

PRINCIPLE ALLOW FOR THE ORGANIC EVOLUTION OF ROUTINES AND PLANS Hard to specify a priori Incremental precision Many routines are “unremarkable” * Tolmie 2002

PRINCIPLE PARTICIPATE IN THE CONSTRUCTION OF FAMILY IDENTITY Some tasks are more than work They constitute how we interpret who we are

PRINCIPLE 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”

PRINCIPLE 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

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

FUTURE WORK Develop an activity manager system Evaluate system in terms of identity and control Develop end-user programming method
