For me, a base symbol is a basic configuration of the fingres and the thumb. The base configuration in ISWA tends to be on the edge facing left because that configuration shows all the fingers being articulated most clearly. Sometimes the clearest configuration is facing the reader. The "base" configuration is a defined configuration of fingers, thumb, palm. I don't know if that's clear, but it's what I go on.
Has anyone come across the definition of a base symbol - in the literature
or anywhere else? How would you define the base symbol of ISWA 2010? To
define it I'm explaining the whole system of rotations and orientations
for each given base
symbol- but still how do you explain the base symbol -
does it represent NO rotation and orientation? (because actually it is
marked for rotation and orientation).
Complex question maybe..sorry- would appreciate any feedback.
