Interactive holograms is on my watch list and I'm really hoping something extraordinary will come of it.
Edit: also they're not physically touching anything.
That's pretty fascinating. I'm curious to see the niches this and things like hololense fill. You may decorate your house with these interactive holograms so that anyone who comes over gets to experience a "full" room. While a google glass or hololonse is used more for private matters. Mostly I'm interested how digital decorating will blend into physical spaces. My fiance isn't much for computers and has an eye for older looking furniture. I would love for my hologram aesthetic to blend well with her physical aesthetic, like projecting the days weather and news onto the mirror of our old dresser.
