What the Hell is...Uncanny Valley?

The movie "Polar Express" was panned, with critics contending that the motion capture process created animated characters that were more disturbing than cuddly. And video gamers have remarked in recent years that digital characters are becoming unsettling.

The idea of the uncanny valley has even been extended to photo retouching, as consumers have difficulty reconciling digitally altered photos with their expectations of a subject's appearance. A recent advancement in photorealistic characters from design firm Image Metrics may have provided an answer by analyzing specific movements and timing gestures.

Origin: Japanese robotics inventor Masahiro Mori defined the concept in 1970. He was looking to explain why people suddenly rejected his creations as they became more evolved. Mori based his theories on the philosophies of Ernst Jentsch and Sigmund Freud, in which both men expounded on the idea that something can be familiar and unknown at the same time.

Correction: One of our eagle-eyed readers noted that the connection between Mori's theory and the work of Freud and Jentsch was made after his postulate was released. Mori's work was not based on their philosophies, it is just a correlation that has been drawn by subsequent researchers.
