How to determine if a pointer is rough or accurate

Question

I read this about interacting environments that explain how css can detect if a pointer is touch sensitive or not. It uses a query @medialike

@media (pointer: coarse){
  body{
    // do something
  }
}

but I'm just wondering how to implement it using javascript from jQuery, is this possible?

Thank you and sorry for my english

Answer 1

is_fine = matchMedia('(pointer:fine)').matches
is_coarse = matchMedia('(pointer:coarse)').matches

Works in Chrome for me.
