Are those dots just like a density map/gradient? Or are they real symbols / characters?

    Are there devices that can render those as something that blind people can feel?

      Sure, braille terminals exist. See https://en.wikipedia.org/wiki/Refreshable_braille_display https://en.wikipedia.org/wiki/Refreshable_braille_display for some examples.
