Interesting. Back in the '80s, the ergonomic keyboard [0] designed as part of the Japanese TRON project was originally supposed to be produced in three different key pitches for differently sized hands, based on measurements of Japanese people [1].
Another aspect was that some key columns were splayed, being more apart further away.
It has inspired many follow-ups in the DIY ergo-mech scene in more recent years.
Years ago a chip supplier suggested using their RTOS. We asked what it was called. They nearly shouted, "Industrial standard Micro Industrial The Real-time Operating system Nucleus, haven't you heard of it?" This would begin a year of Google translation of Japanese RTOS docs.
Neat keyboard. Also pretty cool how far the TRON project went and how many parts of computing it influenced.
