Suppose you want to share something with a large audience, a message, a concert or a speech. Only this audience is divided over different locations.
Ideally you want to be at all these locations at the same time and also be in contact with the people.
That seems futuristic but it is realistic! In fact, you are not only everywhere, a live connection is also possible and you are displayed with 4K video quality via a hologram at any location (s) you want. Through a video connection, you are able to connect with your audience from one location and involve them live without delay.
