Obviously they won't have a screen anymore. They'll be pop-up displays. So if you're sitting on a train and your romantic partner sends you a steamy selfie...guess who has an audience?
Has this annoyed anyone else?
If they're tactical screens, that makes sense. But I still don't think transparent displays on personal devices will be a thing in the future.
I suspect it'll be neural implants. embedded on the optical nerve somewhere, injecting hologram-like images into our field of view. Maybe toss in some sort of marking system for our fingertips for the implant to track as an interface device.
this could also conceivably provide tactile feed back through weak shocks to the fingertips, mimicking touching something, giving you the floaty keyboard and private conversations.
don't worry, they'll be so relevant, you'll just think the real content is... just a really clever add.
(Okay, so maybe all you'll see is just advertising. but how is that different than YT already is is?)
Hmmm.... can you imagine if they figure out how to start pumping other sensations? Dr. Sasquatch soap... making you think you smell like a mangy dog. the not-as-itchy socks company... giving you the sensation of itchy socks.
whatever iteration of as-seen-on-YT wonderbra they happen to be on... only to realize, your manboobs aren't actually that large...awkward.
