Origin

1970s: from a translation of Japanese bukimi no tani, coined by the roboticist Masahiro Moti, who created a graph that plotted the emotional response of a human being to a robot against the increase in the perceived realism of a robot; the graph showed a significant dip at the point where the robot's resemblance to a human is perceived to be almost exact.
