Suppose I am a dancer or an actor, and I am charged with giving a performance for an audience. In today’s world, if I want complete freedom of movement, current production practice requires me to use my naked eyes to look at the physical world around me.
But soon production practice will change, due to recent and imminent advances in technology. Performers will be able to see whatever they wish in the physical space around their bodies, without any loss of freedom of movement.
As this happens, entirely new visual languages will develop, to be used by performers. Dancers will see choreographic steps, lines of principle flow, and other useful indications in the space around them, while actors will perceive virtual sets, animated characters, dialog prompts, sight line hints, and other production cues.
Directors will have entirely new, far more visual, ways to communicate with their cast, just as choreographers will have new powerful tools for expressing their vision to the dance troupe that will realize that vision.
It can be difficult to predict what these visual production languages will look like. But it is going to be exciting to watch them develop.
