On Game AI In The Uncanny Valley
An anonymous reader writes "Normally, the Uncanny Valley theory is used to critique graphical realism in games, but it also applies to AI. Therefore, designer David Hayward examines AI's Uncanny Valley over at Gamasutra, citing games from Valve's Half-Life 2 to the interactive drama Façade." From the article: 'There's a small minority of people who are consistently strange in particular ways... I don't mean to pick on them as a group; nearly all of us dip into such behavior sometimes, perhaps when we're upset, out of sorts, or drunk. Relative and variable as our social skills are, AI is nowhere near such a sophisticated level of interactive ability. It is, however, robotic. Monstrous and sometimes unintentionally comedic; the intersection of broken AI and spooky people is coming.'"
When something does not appear human, its human traits stand out. When something does appear human, its inhuman traits stannd out. This is basically what the Uncannny Valley is about. Exactly what should be considered human and inhuman here probably depends on a thousands of factors. Perhaps being "done well" is part of it, but mostly I think more human appearance and behaviour raises the stanndards of craftmanship considerably. When you're using stick figures, it's not a problem if they don't move exactly like Tiger Woods. In fact, it might be uncannny if they did. If you've got spectacular, photorealistic graphics, everything that's not equally realistic gives you the feeling that something is not quite right.
