I don’t know about other countries - in Switzerland there’s something called ‘tactile sign language’. It’s a variation of sign language where the ‘listener’ is holding your hands to track your movements, and it’s commonly used by/with people with impaired hearing and eyesight.

A more universal (and much easier to learn but much slower) variant is ‘lormen’ where you use your right hand to draw letters on the ‘listening’ person’s left hand. E.g. the word ‘hello’ would be: run finger down top half of pinkie, tap tip of index finger, run finger down middle finger to wrist (twice), tap tip of ring finger.
