Dear Bob,
This method of using your hand as a sundial dates back to the early
1500s if not earlier. I've got a lot of information on such methods
in my office (not here), but most is in Latin or German. I'll try to
provide better citations from there early in the week.
The Adler Planetarium has a hands-on model of this type of sundial in
the exhibition, "Universe in Your Hands." (I was the chief curator of
this exhibit for the first 6 years of planning.) In the exhibit, we
invite visitors to find the time by their hand, and tell them how to
do it. I don't recall the AP's website having an image and
instructions there.
More later,
Sara
