I'd love some chording gloves or even just something that senses finger motion from say forearm muscle activity. I'd use it with my current laptops - just lean back and twitch your fingers
I actually tend to do a lot of coding in bed and would love this kind of setup. Or while on an airplane where space is a premium (I hate having my laptop on that stupid tray table).
Pair the glasses with bone conductive headphones and you could be immersed in your world without the silliness of the Apple Vision. And you wouldn’t have to turn anything off during takeoffs or landings…
if it could be refined to the point where it'd be as capable as smartphone thumb typing and deployed as a standalone input device would be a real game changer.
