Uncanny valley revisited

摘要

The 'Uncanny Valley' was conceived in 1970 by Prof Masahiro Mori and details a possible relationship between an object's appearance or motion and how people perceive the object. Initially this research was used without validation. Modern technology has enabled initial investigations, summarised here, that conclude further work is required. A good design guideline for humanoid robots is desired if humanoid robots are to assist with an increasingly elderly population, but not yet possible due to technological constraints. Prosthetics is considered a good resource as the user interaction is comparable to the anticipated level of human-robot interaction and there is a wide range of existing devices.
