My main grievance with Dyson dryers it that it's difficult keeping your hands in the little narrow gap while the jet is blasting your hands, without touching the sides. It kind of defeats the point if you end up touching the dryer. It seems like a case of form over function.

Yep, but I found over time that I tense my arm muscles before going in and now can keep them fairly steady in the middle without touching. Call it a learning curve I guess.

I think it indicates a serious UX problem if users need to do something like that.

I agree. This is not vim, it's a hand dryer. User should be able to master it on the first use.

This can be fixed by measuring user's hand proximity to both sides and adjusting the air jet flow to keep their hand in the middle.

This test was done with a hand dipped in a virus. When in real life this is only used after you wash your hands. That doesn't seem like a very accurate test IMO. Science.

The degree of dispersion should be the same, though, right? It's just that with a lower starting density you end up with a lower ending density. But the relative performance of the methods would still be valid.

if the starting density is insignificant, then the ending density is insignificant.

we expect hands washed in soap to be clean enough to handle food, so they damned well be clean enough to breathe nearby!
