[MaanuAir]

Holographic display projected from whatever wearable: watch, ring, earring, glasses...

You don’t “hold” anything, you interact freely with a screen that appears floating in front of you.

Hey, the projection could be applied directly into your own eye, as only you could see it (or eyeDrop — pun intended — with others ?)

Good luck with that, but hey, Clarke’s 3rd law:

> Any sufficiently advanced technology is indistinguishable from magic.
