Hmm - Toki Pona is a language invented 2001.
Aha - Fully spaced out alphabet.
Neon - Maya.
@JohanEmpa - A group of hobbyist that I belonged to created another small auxiliary language called "ninu" (meaning small).
Ninu used four vowels and 16 consonants to create a maximum of 4096 two-syllable wordstems. One or more prefixes could be added to the wordstem to make phrases. The 64 (4*16) prefixes were single-syllable.
The alphabet was a bit like 7-segment number displays but had eight segments forming a ladder-like shape.
@JohanEmpa - I have a page about it on my old blog. Only in Swedish, though.
That was interesting. It must be a very challenging task to create a new (serious) language.
The 8 finger keyboard with corresponding segment characters sounds like it could be something, somehow. But on the other hand it may be good to move the hands a bit to avoid static work.
Some time ago I saw a keyboard optimized for the German language.
It would be a cool project to do the same, but optimize it for all EU languages.
