Part 7 of the 11 part series Golden Rules of Anthropomorphism and Design. Anthropomorphic products enter the human social space. Humans have the most complex social behavior of any organism on Earth. Anyone or anything trying to join in should be careful to do it right. Although an anthropomorphic product may function perfectly, if it crosses social boundaries it will still tick people off. This can cause the product to become a social reject, which won’t do sales much good. Luckily, it’s not hard to figure out why things go wrong. Imagine a scenario where a person and a product interact, then replace the product with a second person. If the actions of the second person and the product don’t match up, then there’s something off about the product’s design. Image via Anvari.
