 Roboticist Masahiro Mori's essay on human reactions to humanlike entities, "Bukimi no Tani Genshō" (Valley of Eeriness Phenomenon), describes the gap between familiar living people and their also familiar inanimate representations, such as dolls, puppets, mannequins, prosthetic hands, and android robots.The entities in the valley are between these two poles of common phenomena.Mori has stated that he made the observation independently of Jentsch and Freud, though a link was forged by Reichardt and translators who rendered "bukimi" as "uncanny".
