Eye tracking

How do you get inside people's heads to do your research? Or is it all from the exterior? Do you put in probes and things? But my nightmare of the neuroscientist is you just find any way you can to get inside people's brains.

We do a lot of eye tracking.

We also do occasionally fMRI, but we're very interested in eye movements because the oculomotor system spans the whole brain, like from the frontal lobes to the brainstem, cerebellum, you name it.

So it's virtually impossible.

That's what Megan does.

I do work in a lab that has an eye tracking machine.

which is used to measure people's eye movements and see where they are looking at a screen at certain times.

So yeah, again, I guess weird, almost like uncanny prediction of technology.

So, so that, that was extremely cool, and we got a lot of response from a lot of people.

It's an extremely challenging engineering problem to actually build this because you need very precise eye tracking.

You need to know the pupil size, the location, the prescription of the person.

So in a lab setting, it worked pretty well.

So that's kind of the effect that you'd see.

It's very subtle, but it makes a huge difference in the experience.

Right, and there's no eye tracking going on or anything changing in the display.

We're just pulling the focus of the camera in this case.
