Yes, I saw this link. I haven't tried the software. Bliss intrigues me, but I am rather skeptical of the whole premise. I would love to see some research, but it seems to me if someone can communicate with Blissymbolics, at say a fourth grade reading/writing level, would they not probably be able to communicate in the written version of their native language at about the same grade level? Bliss was meant to be a universal written language. It didn't work out. Nowadays its mostly used as a picture communication system for some people who cannot speak, but it's not as popular as PCS or MinSpeak. I've brought these comparisons up before... <http://lists.w3.org/Archives/Public/w3c-wai-ig/1999AprJun/0367.html> <http://lists.w3.org/Archives/Public/w3c-wai-ig/1998JulSep/0493.html> Hmm. We haven't made to much progress on this debate in the last three years! Picture-based communication systems require the active participation of the "speaker" and the communication partner. The idea of a picture oriented web stands this idea on its head and makes the internet content the "speaker" and the CD/LD person the communication partner. The equation still requires extensive customization and specialized learning on both parties. As I understand the problem, certain people on this list are looking for ways to represent or reformat general content so that it can be conveyed in a picture-oriented format. Yet the audience we are primarily interested in providing this service to do NOT themselves communicate with a picture based systems! Bliss has been around since World War I. People have been using pictures to communicate since before there were cave drawings, but the field of Augmentative and Alternative Communication (where people first tried to formally substitute pictures for voice) is maybe 30 years old. Gregg could probably tell us when the term was first used. The point is that some very learned people have been trying to systematically replace words with pictures for a few decades now and the best they have come up with is PCS or MinSpeak, both of which end up being highly customized to the individual involved! I will also go so far as to mention hieroglyphics. How transparent do you find that picture-based communication system? I submit that these examples go pretty far towards demonstrating that the nominal objective of replacing general text with graphics is beyond our reach. (I suspect there is a mathematical proof for this "theorem", but its construction is beyond me. I doubt that formal evidence would go very far in dissuading the proponents here.) I submit that the best we could hope to do is come up with guidance for constructing images that supplement understanding. This latter goal is FAR more usability oriented than being true accessibility. I respectfully suggest we suspend conversation on this topic and conserve our collective energies for topics that offer a hope of reaching some conclusion. Most of the references from the post I cited above have suffered the nearly inevitable link rot. I offer these instead: PCS: <http://don.iserver.net/catalog/piccomd.htm> MinSpeak: <http://www.prentrom.com/speech/aqlsiconic.html> (mostly just a photo of an icon-oriented communication overlay) Sincerely, Bruce Bailey > ---------- > From: love26@gorge.net > Sent: Thursday, April 26, 2001 10:15 AM > To: w3c-wai-gl@w3.org; ward@talkingsigns.com > Subject: RE: Sources and conferences related to cognitive and > learning d isabilities > > At 01:53 PM 4/25/01 -0400, Bailey, Bruce wrote: > >maturity of Bliss > > http://www.handicom.nl/english/SymfW/index.asp > describes "Symbol for Windows" a program for manipulating Bliss symbols, > etc. > > We may be able to "write what we mean" sooner than later? > > -- > Love. > ACCESSIBILITY IS RIGHT - NOT PRIVILEGE > >
