The design of urinals can be a bigger challenge than one might initially believe, especially for those who don’t have any use for them (a large portion of you). “It’s just like a hold in the wall to pee in, right?” Wrong. There are subtleties to a well designed urinal which even the veteran user experience designers can miss.
In fact, even if we restrict the problem space to just urinals that are equipped with infrared sensors to detect usage and automatically flush, there are still issues to consider.
