There are many different senses that can come into play. For humans, the primary ones are sight, sound and gross physical locations (bumping into something). Ben makes a point of saying "human-like AGI". If we were shooting for fish-like, we'd need to include the lateral line, which is a sensory organ that humans simply don't have (its used to detect movement and vibration) Of course, I'm interested in "science-like" AGI -- so, for example, in atomic-force microscopes (AFM), its been noticed that stiction (the stick/slip friction that you talk about) is a very good way of sensing atomic-scale properties. There's been some effort to attach an AFM to a spring-and-lever-mounted, motorized ball/handle-grip, "haptic interface" so that humans could directly sense, via arm and wrist muscles, atomic-scale Casimir forces & etc. My point is that the world of sensory input can be much richer than a small number of basic senses. We can already augument human vision with infrared googles, but it would be even cooler to see in four primary colors (appearently 1 on 50 women (but no men) have more than three color receptors in their retina) Now that would be something. --linas ------------------------------------------- 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=126863270-d7b0b0 Powered by Listbox: http://www.listbox.com
