[aprssig] "Blind" APRS

[Patrick]

We were chatting about APRS on the way to work the other day on the local repeater.  One
of the guys in the discussion brought up something I've never really considered.  Is
there any currently system(s) for using APRS which would be usable by a blind operator?

If so, does anyone here know of any end users of such systems that wouldn't mind trading
a couple emails on the subject?  I'm prepping a presentation on APRS for January, and
thought that adding some content on that aspect might ensure that even people who know
about APRS might learn something they didn't know before..
