I guess we can take this off the main ASVS list, but the SWAN project 
may be of interest to others, so I'll briefly point to my Sonification 
Lab's research Web page at

http://sonify.psych.gatech.edu/research/index.html   and more 
particularly, the SWAN page at


Sorry, both of these web sites are a bit sparse and not quite up to 
date. I can provide more details to anyone interested. I will suggest 
that this group may be interested especially in the System for Wearable 
Audio Navigation (SWAN), the Sonification Sandbox, and the Audio 
Abacus, these last two being software for displaying quantitative data 
(feel free to download and play with them).

In our work we are obviously very interested in the issue of mapping 
data to auditory display parameters, which is a key design concern for 
this ASVS system. For an auditory display to be acceptable and 
effective, you need to get the mappings right; but not just the 
mappings--also the polarities. For example, Will mentioned mapping 
increasing color onto increasing pitch. This seems reasonable, and will 
probably be the most suitable arrangement. However, note that (1) not 
everyone shares the same mental models about how some things "should" 
be represented with sound, and (2) there are many similarities, but 
also some key differences between the way sighted and blind listeners 
interpret what they hear in auditory graphs (at least in our research, 
that is).

I guess the message is, as Will said, to follow a user-centered design 
approach, and also to make the system flexible/customizable, or at 
least highly learnable.
