The future certainly involves spectacles/contacts that provide augmented reality. The jury is still out on how it will be controlled.

I have suggested a thin glove, or implants in the fingertips (depending on how dedicated you are).

Voice will certainly have its advocates. I think ultimately it will be a turn off (don’t you just hate people talking into a phone that isn’t there?), but something that lets you quietly sound out words could work.

Myo have a gesture control band. It’s a contender, although I would expect it to eventually be incorporated into smart clothing.
