Smart Homes

Is it possible to
c
reate 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

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.”

Why?

Peace of Mind

O: over various devices

DIY: over what they
installed and enabled.

Control

Barrier 1: High Cost of Ownership

Consultant visits not a big factor

Two Surprises

Low perceived value of

additional applications

Barrier 2: Inflexibility

Structural or Retrofit?

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 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

Remote access

Tension between convenience and security


Barrier 4: Difficulty Achieving Security

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
