Saw this alternate entry device announced at CES: https://www.charachorder.com/ SelfieType, using a camera to watch your fingers, looks even more futuristic: https://www.androidauthority.com/samsung-selfie-type-demo-vi...
I would prefer to have camera read my lips rather than read my fingers as I type on nothing.
It reminds me of a talk someone gave about this ad-hoc verbal shorthand someone invented so that they could use speech-to-text to code. The talk sounded really funny but the process did seem fairly productive.
