Hello, we're here today with Bonnie Chen.

Bonnie is a recent graduate of UCSD and she's working in a design lab here

this summer and heading on to University of Washington for her PhD this fall.

And when Bonnie took my class, she made a really great application and

we wanted to share that with you today in paper prototype form.

To give you a sense of what running through a paper usability

study looks like.

Bonnie, do you want to tell us a little about the World Kitchen app?

>> Sure, so the World Kitchen app is an app that is

supposed to be a cultural experience for people who use it.

So it's trying to connect people from different cultures, specifically at UCSD.

>> And so this is like there's a weekly lunch event that this is drawing on.

And so there's a weekly lunch event where students get lunch

that's cooked from a different country each week and in your app, people

get to learn a little bit more about the background of that food and culture.

>> Right, so in my app, I wanted people to learn about different

foods that they might experience, and also the culture,

including names of people from different countries, how to pronounce them.

Or Common phrases that they might say.

>> Cool and so here we've got a paper prototype of the app that Bonnie's made.

And I'm going to be the user in this case.

And okay, so I'm ready when you are.

>> All right, go ahead.

>> So, I'm going to pick a country and today's lunch is USA, so

I'm going to click USA.

And here I see the different dishes and I'm going to click on mac and

cheese to learn more about mac and cheese.

Okay, for somebody watching this somewhere, this is a cultural experience.

All right and then okay I can read about mac and cheese here,

I can get the recipe or submit a recipe.

I wonder what this chat does.

Aha, so I can learn how to pronounce American names like Scott or

have greetings like, what's up?

And now I want to go back.

And I'm going to submit a recipe.

Okay so here, I can add ingredients.

And so I'm going to add an ingredient, macaroni.

[LAUGH] And then I'm going to add another ingredient.

Nice drop down, and I'm going to add cheese.

Okay, now I'm going to click Submit, and the recipe is submitted.

What else could I do with this app?

>> Well you can get the recipe and you can click to enlarge it, I think they'll just.

>> All right, well I'll go back and I'm going to get the recipe.

And let's see if the zoomed in mac and cheese.

Awesome, there we go. >> [LAUGH]

>> So here's Bonny's prototype and

when you run through your paper prototype like this,

you'll see a bunch of different things.

One of them is that if something happens on the fly,

where you want to be able to add an individual element, no problem.

You just grab a piece of paper and you write on it.

Or if there's an issue, you can update things,

change things, whatever, right on the fly.

In this case I was able to figure out my way around this app pretty easily.

Usually it's the case that when you start out with something new,

it'll be more difficult.

And so paper prototypes are a really rapid, fast way to work out the kinks in

your app, try out alternatives, get feedback with users.

And they're great for collaboration too because unlike code where it's daunting.

I mean you're not going to get everyday folks to write code with you.

With something like a paper prototype you can get the user to be like okay,

I'm going to draw my screen here [SOUND] and then it's part of your interface.

So this, in a nutshell, is how you test your paper prototype.
