Colours for Presentations

“It wasn’t until I had my vision tested that I discovered I had a green colour deficiency and so colour overload is a problem, such as occurs in some pie-charts. I tend to use blue as this is usually a safe colour for presentations and when developing web pages if you have a colour deficiency – blue, pale colours.  When items are highlighted, the text goes white on a blue background.

To show you how this looks I have made a PowerPoint presentation about colour deficiencies – it is available for download from Slideshare.”

YouTube to make procrastination productive!

“I use Youtube  when I am procrastinating about what to write or revise. I find it helps my concentration and is a more productive way of taking a break, whilst keeping me centred on the project.”

Refseek have several sites that offer videos for various topics besides YouTube university and Apple iTunes U.

Linearise layout of tables and presentations for screen reader users

“If certain things aren’t designed in a way which is friendly towards my screen reader, if I struggle to navigate pages of notes or what have you, then I find I just give up. …It very rarely happens, but there have been times, like for the last year we had presentations we had to do for French. Otherwise we used to have to produce a sheet that went with the presentation, like a document, and I used to have to get that e-mailed to me. Now if there were tables in that, you had to set them out in a very standard way, you couldn’t have a non-standard table, one of those funny shaped things, you’d have to have just a plain table. If you’d pulled it off a website, well fine, but then edit it, because otherwise I can’t read it.” David –  Politics and French

WebAim provide very good examples alongside their articel on Creating Accessible Tables

“Here is a table which was created for visual effect:

toilet in a table

The visual user will read: “Basement Toilets Must Flush UP!”

The screen reader will hear (or feel via Braille): “Basement UP! Toilets Flush Must”
