US mouse movements are obviously very vigilant, some people say they're the strongest mouse movements ever seen.

Since this is a serious website: I'd be genuinely curious how mouse velocity and trajectories differ between cultural and environmental settings (apart from hardware, that's boring and should be normalized).

There was a time when studies made headlines that were exactly about the relationship between mouse movement, typing etc, and psychiatric disorders as well as physical health.

Obviously, both are related.

If you ask me, Ad tech would probably be able to tell your denominated faith using this data, when there's enough of it...

Genuine question: would right to left language based interfaces have different type of movements and thus training data than left to right language ones?

I'm sure detailed mouse and keystroke data can actually leak health data from subjects. What are the odds one can detect early parkinson disease from mouse wiggle data? If such data leaks away health status, I think capture should be forbidden under current rules.
