Notation systems for tactile sign languages

[Zwitserlood, Inge]

Dear all,
One of my students is writing a thesis about tactile sign language. She
would like to know which notation systems are used to transcribe these and
whether there are notation systems that are specifically designed for/aimed
at transcription of tactile sign languages. If any of you knows about this,
could you please contact me?
Thanks!
Best,
Inge Zwitserlood
