Family Control Smart Home
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 35: Principles of Smart Home Control](https://reader036.fdocuments.in/reader036/viewer/2022062705/55665ce8d8b42aa21e8b492e/html5/thumbnails/35.jpg)
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon
Family Control Smart Home
PRINCIPLE ALLOW FOR THE ORGANIC EVOLUTION OF ROUTINES AND PLANS
Hard to specify a priori
Incremental precision
Many routines are “unremarkable”
* Tolmie 2002
![Page 36: Principles of Smart Home Control](https://reader036.fdocuments.in/reader036/viewer/2022062705/55665ce8d8b42aa21e8b492e/html5/thumbnails/36.jpg)
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon
Family Control Smart Home
PRINCIPLE PARTICIPATE IN THE CONSTRUCTION OF FAMILY IDENTITY
Some tasks are more than work
They constitute how we interpret who
we are
![Page 37: Principles of Smart Home Control](https://reader036.fdocuments.in/reader036/viewer/2022062705/55665ce8d8b42aa21e8b492e/html5/thumbnails/37.jpg)
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon
Family Control Smart Home
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”
![Page 38: Principles of Smart Home Control](https://reader036.fdocuments.in/reader036/viewer/2022062705/55665ce8d8b42aa21e8b492e/html5/thumbnails/38.jpg)
Scott Davidoff, Min Kyung Lee, John Zimmerman, Anind Dey | Carnegie Mellon
Family Control Smart Home
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
![Page 39: Principles of Smart Home Control](https://reader036.fdocuments.in/reader036/viewer/2022062705/55665ce8d8b42aa21e8b492e/html5/thumbnails/39.jpg)

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

and control
Develop end-user programming
