sometimes the interaction concept creates a plenty of disinformation. interaction is percieved as something the user can do and also the camera moving during a show is somehow interaction? I think interaction in performing arts is more than that, is interface, is connection, is response, is communication between human and the machine. When I was at the University my studies after the second year took a clear direction, computer mediated communication. Thid "mediation" starts with a phone call and put the flowing border on the next AI issue so everything has to pass through the machine, has to be analyzed, translated, computed, interprtated, modified and finally exported as a final result back to the human senses. I don't think a simple digitalization is interaction, interaction is digitalization and interpretation of the content. Long live to interaction!
