Uncanny Valley

The uncanny valley is a hypothesis in the field of human aesthetics which holds that when human features look and move almost, but not exactly, like natural human beings, it causes a response of revulsion among some human observers. Examples can be found in the fields of robotics,^[1] 3D computer animation,^[2][3] and in medical fields such as burn reconstruction, infectious diseases, neurological conditions, and plastic surgery.^[4]The "valley" refers to the dip in a graph of the comfort level of humans as subjects move toward a healthy, natural human likeness described in a function of a subject's aesthetic acceptability.
