In a very Infocultist move, one dental school is using human-like simulations to teach dental work. And these sims are actually based on sex dolls. Yes:
one of Japan's top sex doll makers, Orient Industry, was brought in to help design and craft realistic skin, tongue and mouth areas.
The jokes really just tell themselves, don't they?
"We think it's OK for people to be tense while training, and to make mistakes, because, well, this is a robot."
"We considered the motions of the tongue and mouth lining separately."
Showa Hanako 2 has several major upgrades over her predecessor, Showa Hanko 1, for example, her skin is now made of silicone rather than PVC and she moves much more realistically.
