However, the unsolved core issue in the field of vehicle automation is to know how to successfully communicate with pedestrians in a way that is efficient, comfortable, and easy to understand. To make technology trustworthy, automated vehicles must transmit crucial information to pedestrians through a human-machine interface, allowing pedestrians to accurately predict and act on their next behavior. (See “Turning Point” in this issue for an interview with Mori.).Īutomated vehicles need to gain the trust of all road users in order to be accepted. The following is the first publication of an English translation that has been authorized and reviewed by Mori.

Although copies of Mori's essay have circulated among researchers, a complete version hasn't been widely available. Now interest in the uncanny valley should only intensify, as technology evolves and researchers build robots that look human. Some researchers have explored its implications for human-robot interaction and computer-graphics animation, whereas others have investigated its biological and social roots. However, more recently, the concept of the uncanny valley has rapidly attracted interest in robotics and other scientific circles as well as in popular culture. The essay appeared in an obscure Japanese journal called Energy in 1970, and in subsequent years, it received almost no attention.

This descent into eeriness is known as the uncanny valley. In particular, he hypothesized that a person's response to a humanlike robot would abruptly shift from empathy to revulsion as it approached, but failed to attain, a lifelike appearance.

More than 40 years ago, Masahiro Mori, a robotics professor at the Tokyo Institute of Technology, wrote an essay on how he envisioned people's reactions to robots that looked and acted almost like a human.
