[accessibleimage] Tactile arrows

Hi all,

I was wondering what experience people had with arrows (or stair symbols) on
tactile diagrams?
For example, as anyone found any shape, design or size of arrow to be
superior to others?
We are trying a 'saw-tooth' arrow.  Put simply, this a line that feels rough
in one direction and smooth in the other, hopefully indicating direction.
Has anyone had experience with this?

Regards

Don

Hi,
Sending a notice about an article in the Feb 2005 issue of JVIB vol. 99
number 2
Tactile Graphics: An Evaluation of Substrates for Tactile Maps and
Diagrams by
Sarah Jehoe, Simon Ungar, Don McCallum and Jonathan Rowell.
Haven't read it yet, but surely a good read.
Regards,
Lisa
