[Oberon] Have MenuInputTablets confirmed ETHO's TUI?

[eas lab]

I see the public inputting to their tablets via:
 1. see the menu;
 2. select from what is seen.

This is how ETHO works; but never became popular.

Will these new users, in future, dislike the idea of using a computer
by looking up-and-down [like a chicken] to see the display and the
keybrd alternatively?

A stenographer or 'typist' who doesn't need to access all the extra
keys, which computing has introduced, since the original optimum
keybrd-design, can operate like a skilled pianist and never need
to look down at the keybrd.

But with the menu/ETHO method, you can select in one-operation, what
keying would need 50 operations for.

So how will it evolve in our fast moving future?
