There is also the advantage that it has T.V. Raman in charge of it, who makes sure it's well designed and that it continues to meet the needs of Emacspeak users. Along similar lines, somebody at a W3C conference once suggested to me that if you really want a superbly designed technical solution to a difficult problem, bring together 4 or 5 if the best people in the field and give them absolute freedom to design the protocol or language that is needed. Returning to Emacspeak and other non-visual user interface software for Linux and Unix environments, I also think the success of projects is facilitated by the extent to which some of the developers are also users. At a minimum, it provides a smaller feedback loop than is available under circumstances in which the developers aren't intensive users of the software. I look forward to further developments with AsteR; there is nothing that even attempts to equal its functionality. Apparently there's a proprietary tool which will convert MathML to words that can be read by a screen reader. I'm sure I don't need to explain to this audience how primitive that is by comparison with the audio formatting, style language and structural browsing that AsteR offers. The lack of user interface innovation in "assistive technologies" is as apparent as ever - it's still mostly about "screen readers" providing access to visual interfaces rather than the design of more effective auditory (or for that matter, tactile) user interfaces. ----------------------------------------------------------------------------- To unsubscribe from the emacspeak list or change your address on the emacspeak list send mail to "firstname.lastname@example.org" with a subject of "unsubscribe" or "help".
