On the Ishiguru robot and uncanny valley I think the simulation which we're creating of other people is closely based upon the sort of multi-modal integration going on in our own brains - the "dynamic core". So seeing the Ishiguru robot as a static photo and seeing it moving are handled by different regions of the visual cortex, and we normally expect there to be a certain characteristic type of synchronisation going on between these two areas, based upon the way that we ourselves move (maybe with an individual specific delta applied, as in eigenfaces). When there is a slight synchronisation mismatch (you could also call it a prediction error) we get the uncanny feeling. An extreme form of this mismatch is the nausea felt by users of full immersion virtual reality, or car sickness. Here your eyes are telling you that you're moving in a certain way (visual odometry/structure from motion) but this doesn't tally with what your vestibular system is telling you (you're sitting still). I think that there's a fair chance that the same mechanism responsible for VR nausea is also responsible for uncanny valley sensations. Of course we all know that the makers of horror movies actively exploit the uncanny effect, and I could go out even further on a speculative limb and suggest that some forms of post traumatic stress experienced by soldiers after hand-to-hand combat originates from sustained exposure to prediction error specifically related to modeling other individuals. ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=117534816-b15a34 Powered by Listbox: http://www.listbox.com
