00:00:02.880 --> 00:00:06.431
Prototyping helps you test and validate your designs early

00:00:06.431 --> 00:00:12.080
so that you can refine or even rethink your ideas and avoid costly mistakes further down the road.

00:00:12.080 --> 00:00:18.450
*Paper prototypes* are the fastest and cheapest way to get ideas out of your head and into users' hands.

00:00:18.450 --> 00:00:21.131
While digital versions might look more pleasing,

00:00:21.131 --> 00:00:27.211
you can create multiple versions on paper within a fraction of the time it takes to create a single one digitally.

00:00:27.211 --> 00:00:31.339
Paper prototypes also make it simple to conduct a Wizard of Oz session

00:00:31.339 --> 00:00:34.533
where you swap out elements to simulate interactions.

00:00:34.533 --> 00:00:40.018
Once you test and weigh your options, you can proceed to the digital version with the shortlisted option.

00:00:40.018 --> 00:00:42.949
If assembling paper prototypes feels cumbersome,

00:00:42.949 --> 00:00:45.472
you can take pictures of your paper wireframes

00:00:45.472 --> 00:00:49.782
and turn them into digital prototypes that users can use on real devices.

00:00:49.782 --> 00:00:53.206
Turning sketches into prototypes is as easy as taking a picture with

00:00:53.206 --> 00:00:56.286
your smartphone and linking different screens.

00:00:56.286 --> 00:01:00.930
You can use dedicated prototyping tools or even regular presentation tools

00:01:00.930 --> 00:01:04.798
to create a digital prototype from hand-drawn wireframes.

00:01:04.798 --> 00:01:09.838
The digitized paper prototype will be easier to handle for you and your users

00:01:09.838 --> 00:01:13.360
while still giving you the speed and flexibility of sketching.
