Human anthropology and other puzzles

I know what anthropology is — the study of evolution and different cultures. From dictionary.com:

1.	the science that deals with the origins, physical and cultural development, biological characteristics, and social customs and beliefs of humankind.

2.	the study of human beings’ similarity to and divergence from other animals.

3.	the science of humans and their works.

But how does anthropology help to design a keyboard? I saw that in a keyboard publicity claim — “close analysis of human anthropology.” Did the inventor/s (I won’t say who, because I don’t want to embarrass them) perhaps mean “anatomy”? I myself am leery of someone who can’t tell the difference, or worse, throwing around what they think are big important sounding words. That suggests to me that they are using “ergonomic” as a buzzword to sell their product, having no clue what it really entails — not only layout, but design that accounts for posture, impact, amount of force and so on, and materials that are suited to those needs. Ergonomics is not just a fad — it is vital. And I expect that anyone making a truly ergonomic product would not make the mistake of using such out of context words.
