That thing is called a CAPTCHA.

You do have to solve a CAPTCHA as well.

But then, first you take a screen shot, and then you draw something that is related to it.

Then of course, you fill out the CAPTCHA because you help us digitize a book.

While you're typing a CAPTCHA, during those 10 seconds, your brain is doing something amazing.

Let me now tell you about a project that we did a few years later, which is sort of the next evolution of CAPTCHA.

Imagine you're using the Internet and you see a CAPTCHA that you think is somewhat peculiar, like this CAPTCHA.

And basically, since we released it about three or four years ago, a lot of websites have started switching from the old CAPTCHA where people wasted their time to the new CAPTCHA where people are helping to digitize books.

See here's the thing, each time you type a CAPTCHA, essentially you waste 10 seconds of your time.

CAPTCHA Project is something that we did here at Carnegie Melllon over 10 years ago, and it's been used everywhere.
