What eyetracker Hikaru is using? (Serious question)

Hi,

As some of you know, I'm using an eyegaze / eyetracker due to my disability.

This is the current one I am using https://eviacam.crea-si.com/ it's pretty decent but sometimes, it's not enough in speed chess.

A few days ago, I saw Hikaru doing an eyetracker speedrun, and he was able to move really fast and could draw arrows too (I can't draw arrows as I can't use right click and dragging at the same time)

This is the video

I just want to know what eyetracker he was using on that video and if I could download/buy it, I really need something like that...

Hikaru was using a mouse

Wait, my bullet would be 2000 if I use it too.

how

Hikaru is using mouse, it just shows what he's looking at on the board.

hikaru was just using eyetracker so you could see what he does and stuff. he used his mouse to move i think

wdym

Is it cheating to use eye tracker?

Why would it be cheating. is using a trackpad cheating?

Ohhhh, well this is disappointing 

Its basically a software that helps u move faster than mouse at times.

It's the exact opposite tbh

no it is a software that help ppl like Bora who cant use a mouse play chess or do stuff on a comp

oh

rip

oof

of course it is you asked us

Eye trackers track where your eye is so you can see it for content. What Bora uses because he has no mouse is different

chromebooks do be like that sometimes
