At some point everybody will be able to wear lightweight and affordable high quality XR glasses. A really good version of this is still some years off, but it’s fun to think about it now.
One of the things you will be able to do with those glasses is simply point your finger and draw in the air. Everybody who is in the room with you will be able to see your drawing, and they will be able to make their own drawings as well.
Of course all of this will be tied to artificial intelligence. After you draw something, you will be able to say things like “What would a couch look like right here?” or “Show me what this would look like as a real vase.” Your drawing will then come to life for everyone as something that looks realistic.
I wonder who just this one feature will change communication.
