You’ve seen them in futuristic or sci-fi shows, but do they actually exist? Sorry to say this, but although LCD displays has replaced the bulky CRT displays within the past decade, it seems kind of dated. You could say that, despite recent advancements in technology, it still feels that I’m living in the past.
However do actual interactive mid-air holographic screens exists? Well…
In the above video, there’s a hand tracking system and image is drawn with lasers with water mist or smoke (seeing laser between point A and B is not possible unless there are fine particles in between). How this works is similar to a projector display, but with the screen being in mid-air. As you can see, there’s a glass casing surrounding it and the lighting surrounding it being dark.
I don’t even know why I’m writing this…
