I found some wrist concepts, if we want to go the wearable route. Also a ring possibility.

Because I'm extra as heck here are my scribbly take on a mix of both wearables, with a holo-interface for a screen/keypad, with the ring on a dominant hand for voice stuff.

I'm not married to any of this, jsyk, I'm bored at work rn and spitballing ideas.
