Google Group For Package G-Client

I've created a Google Group for package G-Client here: Emacs-G-Client. If you are using package G-Client you can use this group to discuss your experiences with other users. Note that the codebase for this package is evolving actively under SVN at lisp/g-client .

An Essay On Eyes-Free Computing

I just posted an essay on eyes-free computing to my MathZomeblog. This essay highlights the relevance of ZomeTool in teaching mathematical concepts to students who are visually impaired. More generally, it describes my experiences as a mathematician who cannot see. I'm posting the abstract here; the complete essay can be found on my Web site.

The experiences described in this essay have influenced the software I have built and use on a daily basis; it should be of interest to:

• Emacspeak users wishing to understand why things look like the way they do in Emacspeak.
• Students with visual impairments who are entering the field of mathematics.
• Teachers working with visually impaired students.
• And the generally curious mathematician who wishes to view the world from a different perspective.

Abstract

This essay outlines some of my experiences as a mathematician who cannot see. Note that I transitioned to being a Computer Scientist during Graduate School. However I strongly believe in the edict Once a mathematician, always a mathematician! — my training in mathematics continues to influence the way I think.

I've been unable to see since the age of 14, which means that I've studied and practiced mathematics predominantly in an eyes-free environment. This essay is my first conscious attempt at asking the question What is involved in doing mathematics when you cannot see? I hope that some of the experiences outlined here will prove insightful to mathematicians at large. At its heart, mathematics is about understanding the underlying structure inherent in a given area of interest — and where no such structure exists — to define the minimal structure that is needed to make forward progress.

The general perception that mathematics might be hard to do in an eyes-free environment probably traces itself to the common view of mathematics as a field where one performs copious calculations on paper. I'll illustrate some of the habits and abilities one evolves over time to compensate for the lack of ready access to scratch memory provided by pencil and paper when working in an eyes-free environment. In this essay, I hope to demonstrate that mathematics in its essence is something far bigger. By being bigger than calculations on paper, not being able to see rarely if ever proves an obstacle when it comes to doing mathematics; the challenges one needs to overcome are primarily centered around gaining access to mathematical material, and communicating ones insights with fellow mathematicians. Thus, a large portion of this essay focuses on solutions to the challenges inherent in mathematical communication.

Web 2.0 And The Emacspeak Audio Webtop

Blogging while at WWW 2007. I attended the W3C AC meeting the first two days of the week. The highlight for me from the AC (Advisory Committee meeting was a panel consisting of TimBL and Tim OReilly at the end of the day yesterday. It was fun to hear Tim OReilly define Web-2.0 --- he is credited with originally coining the term, but in the last year, Web 2.0 has often been lightly equated to dynamic Web applications that use JavaScript to the extent that many assume that anything that doesn't use JavaScript is not Web-2.0!

The gist of Tim O's definition of Web-2.0 was to point out that once the Web had gained sufficient coverage and scale, it became possible to build application services on this Web that drew their value from aggregating the data on the Web; his examples ranged from Google to Amazon. His comments were insightful --- my own view now is that Web-2.0 should have been called Web^2 i.e. this current revolution is about applying the power of the Web to itself.

The other amusing piece while running around at the conference and observing what everyone is working on is to realize that now that Web Gadgets and the like are popular, it's now considered a fine idea to write light-weight site-specific tools. Notice that Emacspeak has had this since the late 90's in the form of first the websearch module, to be later joined by url-templates. I believe these innovations arrived earlier on the Emacspeak Webtop as compared to the rest of the Web for the following reasons:

• Emacspeak relied on Emacs/W3 for Web functionality,and when that browser stopped being maintained, there was a strong need to develop Web tools in the context of Emacspeak.
• The visual Web was getting too complex for use via speech output, and given the flexibility of the Emacs environment, and the arrival of XSLT in 1999, things were well set up to build a powerful set of Web access wizards.
• Task-oriented Web tools in Emacspeak led to the conceptual Web Command Line in Emacspeak at a time when command-line interfaces were considered passe'.

Incidentally when I showed others working in the field of accessibility these Emacspeak tools during their early days, they were promptly dismissed as site-specific hacks that wouldn't scale in the face of generic screenreaders that would handle every web page. With the visual Web getting too busy for everyone mainstream users now have access to productivity solutions such as Apple's Dashboard Widgets, IGoogle modules that can be placed on a Web page or the desktop, and other comparable tools. It will be interesting to see how much longer blind users saddled with commercial screenreaders will have to wait before seeing similar tools emerge in their world --- just remember, when that does arrive, Emacspeak had them in 2000!
