They are. When I end up at robots as I always end up at in research, it is the heavy ABSTRACTION that designers need to make in order to find what’s sensibly inbetween a living vs a constructable thing.
Here, these artificial finger people worked hard and read the research and did their own and came up with 15 dimensions of touch, which is more than I’d expected but they all are unique and make sense.
They may or may not match up entirely to human experience BUT they are a darn lot closer to anything else out there. They fit the subjective experience of each while being quantifiable, which is fantastic.
Why does this doorknob with the zinc coating feel different than the doorknob with the brass coating?
Now I have some idea.
