you can come up with some metrics to mathematically analyze certain aspects of the user interaction And we have done that! Fitts’ law [1] gives us a very good way of quantifying certain aspects of user interface design. I can’t tell you how many UIs I’ve used (lost count) that have ignored this very basic principle and as a result they’re extremely frustrating to use. In any case, it may not be what garganzol was talking about, but it did resemble a comment I’ve seen made many times. In the vast majority of cases I’ve seen, people who claim that math is inapplicable to some problem are completely unaware of a rich and storied field of mathematics dedicated to that topic.
