Won't people know you are there when they feel water on their heads? All those systems work in a static preset state. Holograms that use light, for example, require a container and super cooled gas. Moving the projector requires you to move the container, and people will notice the container when it hits them.

They must have a refresh rate of over 200 times a second." 3D visualization technology exists, you know. For instance, there's the water droplet projection system used by the Vocaloid concerts.
Aug 4, 2021 at 4:23 comment added user64888 Nanomachines would not be inherently better than miniaturized electronics. You only need the parts to be a little less than a millimeter in size. Reducing the size a thousand times more won't help. Further more, this means in addition to all the things above you need to add nanotechnology to that.
