[BlindMath] Giving presentations

Wed Oct 11 18:53:31 UTC 2017

Lukasz/Jason,

This is dangerously close to re-inventing the wheel.

Jason is right: use of markdown to create HTML does make use of MathJax (or can to be perfectly specific) so the finished product for the audience is accessible to the speaker. This obviates the need to have two documents to track, whether the speaker's notes be in hardcopy or on a second device.

Slidey is a presentation format that has the best of HTML and adds slide transitions etc as per a standard presentation. 

Lukasz: If you are suggesting someone write up LaTeX in a classroom situation for instant display, then it is interesting, but hardly practical for anything but the simplest things. In my experience, no one types up LaTeX sufficiently quickly or accurately to do this for more than one or two items per class. Students do not want to sit around watching the speaker perfect their slides, which should have been done before class.

Jason: I am interested in knowing what editors you are referring to. I've not seen any editor to date that is any better than the editor I wrote for my own use (beta testers welcome, but you must use R; write off-list)

Also note, There is the LEAN editor for Word which has been described on this list previously.

Cheers,
Jonathan

Following on Jason's idea, one could prepare markdown files 1.txt, 2.txt, each of them would have exactly one slide, you would open them in separate tabs of a text editor on one computer, on the other computer you would have for example mathml version opened in browser, made in such a way that you can use single shortcut to switch to next slide (i.e. at the bottom of say 1.txt you would add a link to 2.html and use CSS to add shortcut to it - it may sound like a lot of work but it actually isn't at all).

The only disadvantege is that you would have to change to next slide both on both computers, but I think it could work (or it could be a starting point).

Best,
Lukasz
