- [Woman] Three, nine, two, five, four, six, repeat.

It has a 5.7 inch OLED display, a Snapdragon 855 processor,

and it can track your pupils on a sub millimeter level

with a reported median error of three and a half percent.

Okay, this video isn't really about a three year old phone.

If you wanna watch that review, we did one.

You can still check it out if you want to.

This video is about the camera in this phone, however.

And how researchers at UCSD are using it to do more

Instead, they're seeing if it can measure your pupil size,

for neurological diseases like Alzheimer's.

because when we talk about health and tech,

usually the conversation is around newer devices

So, I wanted to find out more about this technology,

and exactly what other health monitoring can be done

I'm a second year PhD student at UC San Diego

in the electrical and computer engineering department.

and things that we already have around us

how does pointing a smartphone camera in your eye

tell you anything about neurological diseases,

- [Colin] It can be difficult to understand

a metric for different neurological diseases.

And, first I guess to tell you a little bit

- That measurement is really just the size of your pupil.

- [Colin] So it's not just a quick snapshot of the eye.

Actually, it's recording your response to specific tasks.

These are correlated with neurological diseases

because of the connections within the brain

is basically giving scientists sort of a window

into the brain and seeing how we can not basically

identify different traits or different cognitive impairments

by the dysfunction or the function of your pupil response.

can tell scientists a lot about your cognitive health.

So how does this app allow them to do that?

- The way the app works is that it's going to be using

because it includes near infrared cameras.

So these cameras are recording in a non-visible range.

that we and you will see when we look around.

And this is especially important for pupil measurements,

because some people have, you know, dark brown eyes

is gonna be very minimal in the visible spectrum.

But when you look at it in the infrared spectrum,

these sub millimeter measurements of the people.

- There's actually a lot of work going on at UCSD

when it comes to unlocking the technology in your smartphone

- There's a huge sort of library of different measurements

to have these measurements sort of validated

and have them not only validated by themselves,

but validated across many smartphone models.

- Many smartphone models is a key point here too,

because not all smartphones have IR cameras.

The Pixel actually lost them after the four.

Now Vera and I aren't in the age demographic

but he was still nice enough to lead us through

our own pupil exams, which was pretty easy,
