This screen, created on a piece of cardboard with post it notes,
allow people to navigate the hospital system.
They didn't do any programming to make this, but they were able to get a lot of
feedback on the kinds of choices people wanted to make, and
what they expected to see on such a screen when they entered the hospital.
Here's another great prototype that I love, also considered a walk-through.
It's the walk-through of a digital experience.
Now you may be asking yourself, where are the computer screens?
Where's the handheld?
In this project, they realized the most important thing to understand was what was
it like when people first came to the welcome page of the website.
And so what they've prototyped in this picture is the welcome experience.
So their goal was to make the welcome experience feel like
you were walking into somebody's home.
On the ground, you'll see a green sheet of paper.
That's the welcome mat.
So what would it be like to design a website,
where it was as welcoming as if you were walking into somebody's home.
And they were offering you a choice of options,
of things to eat when you came into their home.
They did this walk-through to understand, what are the sequences of events, and
what kind of expectations do people have.
And, how could they use this analogy to inform the design
of their ultimate digital experience.
Here's an example of a touch point.
