Shout out to one of my students for giving me this lead. I have always said that anything can be improved with human factors. Here is one I hadn't thought of.
Pronto has created a new packaging system for condoms that makes it easy to put on. I haven't tried them, so I can't attest to the truth of their claim, but I have read that much of the spread of HIV/AIDS in sub-Saharan Africa is tied to men not wanted to use condoms because they take too long to put on and are often put on backwards. So it is "ease of use" and "mapping" that cause the problems. The same goes for a lot of Western populations, although I have less sympathy for them.
Hurray for Human Factors.
