Robotic Mimic Is Slightly Less Uncanny
Writing by Evan Ackerman on Thursday, 30 of October , 2008 at 3:18 am
Before you judge the performance of this robotic head too harshly, just remember where the bottom of the uncanny valley really is. Yeah, this one is actually pretty good, huh? “Jules,” developed by researchers at the University of Bristol, creates facial expressions by watching human faces and then trying to match them. Jules has a video camera that watches humans, analyzes their facial structure 25 times per second, and then makes dynamic adjustments to 34 tiny servos underneath pliable skin to try to match the expressions as closely as possible. And it really does seem to work a lot better than simply programming a servo movement sequence for “smile.”
I think the key here is that the robot, by duplicating human expressions, may be able to account for important facial muscle motions that we don’t necessarily directly identify with a certain emotion. For example, we can usually recognize the difference between a sincere smile and an insincere one, but it’s sometimes hard to tell exactly what the physical difference is. And this is exactly what lands androids at the bottom of the uncanny valley: doing what humans do on paper, but not being human about it at all.
Despite Jules’ human-like expressions, he’s still a robot to the core… See a video of Jules justifying the destruction of humanity (and he’s got some good points), after the jump.

mouth needs a bit of work, but it is very amazing.
Love the tyraid, he just better not get any limbs or actual motivation, because if he does then i’d have to shoot ‘em.

Безусловно у этого типа просмотра существует большой минус – отсутствие возможности сохранить видео. Имеется альтернатива – это ТВ онлайн. Интересно, когда тебя любят на другом континенте! :)Сегодня в прокат выходит фильм Леонида Рыбакова “Скажи Лео”. emarketer.
