  • Is it possible to create a home environment that is aware of its occupants whereabouts and activities?

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

The Adaptive House, Mozer et al.

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.

  • 14 households with one or more of the following:
  • Remote lighting control
  • Multi-room audio/video systems
  • Security cameras
  • Motion detectors

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

Why?

Peace of Mind

Control

O: over various devices

DIY: over what they installed and enabled.

Monitoring

diversity in installation desires
Diversity in Installation & Desires

From X10 to control a few lights to embedded panels in every room

Control

Media

Security

Environment

Augmented, Not Smart

Not ready for broad adoption

4 barriers

Cost, Inflexibility, Manageability, Security

Caveat 1: Not problems for our participants

Caveat 2: Not answering whether functionality

is generally appealing

barrier 1 high cost of ownership
Barrier 1: High Cost of Ownership

+

DIY: $200 - $60,000, $5,000 median

DIYs trade-off lower monetary cost for time

O: $13,500 – $120,000 $40,000 median

Barrier 1: High Cost of Ownership

Two Surprises

Consultant visits not a big factor

Low perceived value of additional applications

barrier 2 inflexibility
Barrier 2: Inflexibility

Integration Ease or Flexibility

DIY: Use expertise to overcomeOutsource: Choose one brand

Structural or Retrofit?

(9 put automation in place during structural changes)

Surprise:

Thinking ahead to moving…

barrier 3 poor manageability
Barrier 3: Poor Manageability

Our households were well-equipped to manage

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.”

Difficult to customize for Outsourced

barrier 3 poor manageability1
Barrier 3: Poor Manageability

Iteration 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)

barrier 4 difficulty achieving security
Barrier 4: Difficulty Achieving Security

Remote access

  • Eight households currently have remote access enabled
  • Tension between convenience and security

Very technically savvy participants concerned about vulnerability of remote access

Cameras

Door locks

simple user groups for future needs
Simple User Groups for Future Needs
  • 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

concluding remarks
Concluding Remarks
  • 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
