That's pretty sick and honestly easily feasible as we continue to scale down electronics.
What I'm hoping for though is more than just that.
It'd be sick if we could change our eye color on the fly, the tint on your glasses or even write words or scrolling sentences on them. That's not only cool, but it could be like, "You were invited to 'X' party." When I show up there, my eye color changes to a certain hue (or a bunch of hues) and they see that I've been invited.
Also, how about it saving all that we see in order to 'recall' something we may recognize or something that is similar; like, I know I've seen that girl before...but where? *Accessing* Or even better, remembering things we had forgotten. Like "Yo I gave you that last week!" ....Searching for last encounter with 'Joe'....Found one last week...Video loading..."Here you go bro. I'll see you in a week."..."****, I guess you did".
Also, could it scan my eyes to unlock everything I see? Like I look at my phone with the glasses/contacts on and it unlocks or I look at my car and it turns on, or my house or garage and it opens.
Also, this is just for contacts, but what can it display while my eyes are closed? Can I watch a movie? Or look at a visualizer while I listen to music?
