uncanny valley

This week, I would like to explain about an interesting word, "uncanny valley". This word was suggested by a Japanese robot engineering professor, Mori. When a humanoid robot is created with more reality in emotion and movement, we likely to have a positive impression to it, however, in some stage, our impression dramatically fall suddenly. But when more reality is added, our likability increases a lot. This curve, when drew in graph, is called the "uncanny valley". There are many discussions made to explain the relationships between CG animation movie and its box-office revenue. When the reality of the movie is on the bottom of uncanny valley, the revenue tend to become much lower compared to non-real movie or very real movie. Many robotics and CG technicians are seeking for a way to get over the uncanny valley.
