Smart Homes
Is it possible to create a home environment that is aware of its occupants whereabouts and activities?
The Adaptive House, Mozer et al.
Georgia Tech Aware Home
Develop a home that essentially programs itself by observing the lifestyle and desires of the inhabitants, and learning to anticipate and accommodate their needs

Don’t forget Hollywood
It's up to Ben to match wits with PAT's central intelligence and "out-smart" the Smart House once and for all!

Adopting Home Automation
Do-It-Yourself (DIY) Outsourced
Our goal: Better understand current state of home automation and learn from people’s long term use.

Living with Automation
Convenience
“It allows me to be lazy, honestly, because every day [before automation] I would go double check the locks, make sure all the lights are off on all the floors and make sure that everything’s closed.” Technology consumer from DIY house 6, D6_C

Not ready for broad adoption
Caveat 1: Not problems for our participantsCaveat 2: Not answering whether functionality
is generally appealing
4 barriers Cost, Inflexibility, Manageability, Security
![Page 13: Home Automation in the Wild: Challenges and Opportunities A.J. Brush Bongshin Lee Ratul Mahajan Sharad Agarwal Stefan Saroiu Colin Dixon](https://reader036.vdocuments.net/reader036/viewer/2022062506/56649c945503460f94951116/html5/thumbnails/13.jpg)
Microsoft Research 13
Barrier 1: High Cost of Ownership
+DIY: $200 - $60,000, $5,000 median
O: $13,500 – $120,000 $40,000 median
DIYs trade-off lower monetary cost for time
![Page 14: Home Automation in the Wild: Challenges and Opportunities A.J. Brush Bongshin Lee Ratul Mahajan Sharad Agarwal Stefan Saroiu Colin Dixon](https://reader036.vdocuments.net/reader036/viewer/2022062506/56649c945503460f94951116/html5/thumbnails/14.jpg)
Microsoft Research 14
Barrier 1: High Cost of Ownership
Consultant visits not a big factor
Two Surprises
Low perceived value of additional applications
![Page 15: Home Automation in the Wild: Challenges and Opportunities A.J. Brush Bongshin Lee Ratul Mahajan Sharad Agarwal Stefan Saroiu Colin Dixon](https://reader036.vdocuments.net/reader036/viewer/2022062506/56649c945503460f94951116/html5/thumbnails/15.jpg)
Microsoft Research 15
Barrier 2: Inflexibility
Structural or Retrofit?(9 put automation in place during structural changes)
Surprise: Thinking ahead to moving…
DIY: Use expertise to overcomeOutsource: Choose one brand
Integration Ease or Flexibility

Microsoft Research 16
Barrier 3: Poor Manageability
Our households were well-equipped to manage
Difficult to customize for Outsourced
Complex UI Consultant Required“I started explaining the panel (how to call fire department) to them and they looked in dread. People just don’t want to touch it. And my own mother sat in our house in the dark, because she was scared to touch any of the controls.”

Microsoft Research 17
Barrier 3: Poor ManageabilityIteration required
“I thought when I went into this, I’d want my alarm system integrated and I’d want these automatic features firing off in the background like, you know, I’d wake up and music is playing in my bathroom and the lights come up, you know all these Jetson type things. And the challenge with that, while they’re all great, I don’t live that structured of a life, not waking up into [it] every day, and I'm not going in the shower every day at the same time. And you know, I don't want to hear music all the time. So I don’t think the routineness of automation is what I was really wanting.” (D8_G)

Remote access– Eight households currently have
remote access enabled– Tension between convenience and security
Barrier 4: Difficulty Achieving Security
Door locks Cameras
Very technically savvy participants concerned about vulnerability of remote access

• What restrictions would you place (if any) on applications you were interested in buying?
• Presence based security• All other restrictions:
– Adult household member– Child household member– Guest– Household technology guru
Simple User Groups for Future Needs

Microsoft Research 23
• Interviewed 14 households with home automation, DIY and Outsourced
• 4 Barriers to broader adoption:– Cost of ownership (Time & Money)– Inflexibility– Poor Manageability– Difficulty Achieving Security
• Identify directions for future research– Eliminate the need for structural changes– Enable composition of home devices– Simple security that can be confidently configured
