Have you ever wondered why PlayStation controllers use X-Circle-Square-Triangle for the face buttons instead of the more traditional B-A-Y-X that Nintendo has employed since the Super NES days or the mirrored A-B-X-Y that Microsoft overlaid on the Xbox controllers? It’s OK, it’s kept me up at night too. Why? Why? Why?

Thankfully, Kill Screen’s David Shimomura went looking for an answer and he found one by talking to Teiyu Goto, the developer who originally designed the PlayStation controller for Sony back in the mid 90s. Goto revealed that he named the face buttons what he did in a nod to symbolism and semiotics. However, American and European players didn’t have the same connection to Goto’s symbols as a Japanese player would and it caused all sorts of friction within Sony:

Goto wanted to be memorable but he also wanted to make sense, at least in his own mind. “I gave each symbol a meaning and a color,” he states in the same interview. “The triangle refers to viewpoint; I had it represent one’s head or direction and made it green. Square refers to a piece of paper; I had it represent menus or documents and made it pink.” So far so good, sort of. The triangle is reminiscent of an arrow or a direction. It has directionality to it and, even though it’s equilateral, it must point somewhere. The square is a little looser but the connection between a page and the square are strong, at least for Goto. One can construe it as a box and use it for inventory or some other kind of menus. But then things got weird.
