A Few Notes…
❡ Organize yourselves into groups of 2 or 3 persons
–
These will be your group members for the class
–
It’s okay if you don’t know anyone yet, we’re here to make friends!
❡ Please open ilab.zanecochran.com, go to the Physical
Computing page and scroll down to Lesson 2
❡ I need blogs addresses from:
–
Shem & Gabriel
❡ If you did not complete a research survey, let me know!
❡ Everyone please send me a quick e-mail to
[email protected]
Let’s get ready!
❡ What is interactivity? (And what isn’t)
❡ Degrees of Interactivity
❡ User Interaction
❡ Why should we make things interactive?

Interaction
A cyclic process in which
two actors alternately
listen, think, and speak.

What is interactivity?
(And what isn’t)
❡ It’s not the design of the
case or the monitor
❡ It’s not how much
information it can store on
the hard drive
❡ Or its ability to connect to
the Internet
❡ It’s the user interface.
When the user
communicates with the
computer and the
computer responds
intelligently
Degrees of Interactivity
❡ The level of interactivity in an
object depends on how well it
does 3 things:
❡ Listen – How well does it
receive input? Does it
make mistakes?
❡ Think – What does it do
with the information it
gets?
❡ Speak – When it responds,
does it make sense to the
other person?

User Interaction
❡ What functions does this
phone have?
❡ How well does it “listen”?
❡ How does it process and
“think” about the
information it receives?
❡ How does it respond? Does
it do a good job?
User Interaction
❡ How is this similar?
❡ How is it different?
Why should we make
things interactive?
❡ Improve user experiences
–
Better feedback about the things we use
–
Make better decisions
–
Do things more efficiently
❡ Solve old problems with new ideas
❡ More creativity and better art
❡ Technology to make things interactive is easier
to use, more powerful than ever, and cheaper

Imaginary Expressive
Object
❡ What would a person have to see, hear, touch, etc. while
operating the device?
❡ What cues would a person need to understand the interface
with the object?
❡ What gestures/actions trigger the device's behaviors?
❡ Who is the intended audience/user/beneficiary? What
specifically does your device do? Where and when will it be
used?
❡ Why is it necessary/important/fun?
Imaginary Expressive
Object
Quick Look & Reflection
❡ What makes something interactive?
❡ Name a few things that are good examples of
interactive devices. Name a few things that
aren’t interactive.
❡ What was your favorite imaginary expressive
object today?
❡ How would you improve your imaginary
expressive object?
One last thing…
Can I talk to Timothy,
Lawrence, Randy and
Anthony after class?
