I wonder if I have it backed up or could track down what it was again. I was not much of a developer then, but these days it would be simple to wire up simulated mouse events.
My experience with eye trackers was similar. The clicking thing is partially solvable with eye tracker + foot pedal combination, but the biggest turn off with eye tracker was poor support for wider monitors or multiple monitor setup. Eye trackers also require you to be in a certain distance from it which was affecting my posture.
These were some of the reasons why I've built Cursorly https://cursorly.app/ It's still in the early stage but I'd love to hear some feedback. There is a free trial for a few days, but let me know if you want to extended it, I'd be happy to do so.

I disagree with these assertions. There are several options in Talon for eye tracking. Optikey is a nice suite of functionality, but it's Windows-only, while Talon is cross platform. I also have a few users who use the Optikey UI but prefer to use Talon's eye tracking to control it. I've certainly recommended Optikey to users.
The updated direct control mouse mode in Talon 0.3 can be used without any head tracking at all as long as your targets aren't too small.
The zoom mode explicitly uses no head tracking as well.
To click or trigger the zoom mouse, you can make a pop noise, use voice commands, or a physical mouse button, or keyboard, or any keyboard emulating input device (such as a foot pedal), or use one of the dwell options.
