"The group of artists and scientists that had so far done least was the one that had attracted the greatest interest --and the greatest alarm. There was the team working on "total identification." The history of the cinema gave the clue to their actions. First sound, then color, then stereoscopy, then cinerama, had made the old "moving pictures" more and more like reality itself. Where was the end of the story? Surely, the final stage would be reached when the audience forgot it was an audience and became part of the action. to achieve this would involve stimulation of all the senses, and perhaps hypnosis as well but many believed it to be practical. When the goal was attained, there would be an enormous enrichment of human experience. A man could become --for a while, at least-- any other person, and could take part in any conceivable adventure, real or imaginary. He could even be a plant or an animal, if it proved possible to capture and record the sense impressions of other living creatures. And when the "program" was over, he would have acquired a memory as vivid as any experience in his actual life --indeed, indistinguishable from reality itself."
