iOS Spectator View: AR in the TV production

Graphical visualization and 3D simulations in TV shows are well suited for explaining abstract concepts and progresses. Since the 1960s the blue/greenscreen-technique is used in German productions to add graphics. Within the last ten years many broadcasters used virtual studios for their production.  To escape the “green hell”, Augmented Reality (AR) has gotten more popular …
