Anthromimetics - Flattening the Curve of the Uncanny Valley


Image results for anthromimetics are disappointing, so you get a beautiful Hubble picture of the universe instead, the Veil Nebula, via the ESA and NASA, 2021.

A search for anthromimetics wants me to see anthropometrics. Correcting gives me 78 results. Anthromimicry? 10 results. (Two of them are from this weblog, and 2 are from what I would call procedurally generated domain name redirects, kind of like the lists of phone numbers and why you get calls from yourself sometimes. The other sites are circa 2012.)

So I will explain - biomimicry copies biology and anthromimicry copies humans. It's what we're doing to robots to help them cross the uncanny valley. We want them to copy us good so we can believe them. 


A new machine-learning system helps robots understand and perform certain social interactions
Nov 2021, phys.org

"In a simulated environment, a robot watches its companion, guesses what task it wants to accomplish, and then helps or hinders this other robot based on its own goals."

In order to teach robots how to be social, we're just showing them footage of people helping each other, and go figure the robots gets better at figuring out what you're trying to do, and then helps you do it. Sounds simple until you realize that to be "social" is extraordinarily complex, and something that has taken most of us our entire lives to get right (and that's a lot of training data).

Making (and breaking) eye contact makes conversation more engaging

Synchrony - "In the past, it has been assumed that eye contact creates synchrony, but our findings suggest that it's not that simple," says senior author Thalia Wheatley, a professor of psychological and brain sciences at Dartmouth, and principal investigator of the Dartmouth Social Systems Laboratory. "We make eye contact when we are already in sync, and, if anything, eye contact seems to then help break that synchrony. Eye contact may usefully disrupt synchrony momentarily in order to allow for a new thought or idea."

Heart rate synchronization and palm sweat found to be signs of attraction
Nov 2021, phys.org

They set up the "dating cabins" at public events such as concerts and invited young single people to participate in their study.

When two people are attracted to one another, their heart rates tend to synchronize and their palms sweat together.

The scores of attractiveness the volunteers gave each other after a first quick peek did not hold up. Nor did their behavioral clues

Hanako - aka the Uncanny Horror

Post Script:
This one can't make the rounds enough. So here you have it again. You're looking at a screenshot of a humanoid robot designed for dental students. It recoils, it gags, and it squeals in fear and discomfort. If you find the video, you will be horrified beyond repair. That's why I only give you the picture.
