Eye tracking will probably lose the productivity metric, though. When you remove the ability to look at one thing and interact with another, you get farther from the way that humans tend to interact with their immediate physical environment.

I can cut vegetables without looking at them. I can use that dynamic to offset the planning and acting phases of my thought process. Falling short of that efficiency will feel limiting.

I don't click without looking at my mouse pointer. I think it's possible eye tracking is just better than mouse/trackpad.

I often am looking at another element before interacting with it with my mouse. With eye tracking enabled menus hovering over an element immediately because I'm looking at it becomes an annoyance.

Yea, I don't think a 1-to-1 translation of mouse movements with eye tracking is the correct answer here. I do think it's probable that eye tracking + {X} can be a 1-to-1 translation for clicking for 80%+ clicks.

Maybe X is a button on the keyboard. Maybe X is a gesture.

I do, when gaming.

I can think of some Portal puzzles in particular where timing is important, and you need to hold your aim but wait to click until something happens somewhere else on the screen (so the place you're clicking is not the same as the place you're looking).

I think the same thing applies to e.g. recording network activity in Chrome dev tools. My eyes are on the page to see when the thing I'm interested in finishes loading; my mouse cursor is on the button to stop recording.

It's not a super common pattern, but probably common enough that it would be annoying not to be able to do it.

Yea, I agree with this for gaming. Eye tracking as a gaming interface probably requires rethinking a lot about games. In VR for example the movespeed is much slower. In normal video games the character movement is constantly super-human speed, and this is jarring while in VR.

I am speaking mostly about the desktop interactions. In your Chrome Dev situation, I would look at the cursor before clicking on the stop recording button. I think I might be able to trust the MBP trackpad to do a primed click without looking at the cursor, but I wouldn't trust a traditional desktop mouse to have stayed steady enough.

Interesting, I just tried to use my pointer with my peripheral vision, and while possible, it was indeed more difficult and harder to focus on. Something I hadn't tried before.
