Atool is an extension to our previous CamKeys project. Like CamKeys, atool allows keyboard input based on a cheap webcam. Atool adds DDR pads (or other game controller buttons) as an additional input and it allows playing recorded sounds on input events.

I really like using Wordpress for my website and blog but I hadn’t thought until recently about using it as an application framework. Karen and I talked about a site to enable teachers to quickly build topical beginning readers for people with varied interests and abilities. I began thinking about the features such a site would have and found lots of overlap with what Wordpress already provides. A blog post by Steve Winton over at NixonMcInnes encouraged me to examine the possibilities further.

I’m pleased to report that it is really easy to integrate a PHP web-app into Wordpress. I use ordinary blog posts as the books with the <!–nextpage–> tag for pagination and a bit of Javascript for switch accessibility and text to speech. The book creator wizard is simply a set of pages with custom templates. You select some images, provide some captions and a title, and it creates the blog post that is your book. Wordpress provides logins, all the database manipulation, comments, tags, categories, etc. Redirects work fine because Wordpress is silent until you invoke get_header. Query parameters work fine; Wordpress seems to ignore them. Session variables work fine too. So far Wordpress hasn’t gotten in my way once and has helped a ton.

A US federal appeals court on Tuesday ruled that the country’s one-sized paper money discriminates against the blind and told the government to change the currency’s size and texture. It’s taken six years to get this far, and the government may well appeal again. I say give it up and switch to an accessible design.

Notes from a conversation with Karen. Always great fun.

Take pictures of the book during group reading (teacher is displaying it to the rest of the class using a projector say). Make it available for self selected reading later. Perhaps create PowerPoint presentation with the pictures and easily recorded audio of someone reading the text for each page. Enable typing in the text so it can be read using TTS either continuously or one word at a time. Make it easy to share these on some closed site. What about the copyright provisions related to people with disabilities? Public Law 104-197 would allow us to do this in a “specialized format”. That says to me it couldn’t be PowerPoint but that is not problem, we’d just have a specialized player. Very simple to show pictures and play speech. Might even be browser based. Could the whole thing be easily made browser based? Should it be?

Thanks to Martha for pointing out this video: TED | Talks | Tod Machover, Dan Ellsey: Releasing the music in your head (video). Very interesting. I’d love to do something like this for kids. Machover talks about Hyperscore.

24 ways: Marking Up a Tag Cloud is an excellent discussion of how to implement a cloud using CSS. I hadn’t realized that most ways of doing it are inaccessible. I used his approach to construct my query cloud page.

Ian Bicking’s interesting and provocative blog post on HTML Accessibility is a good read. Empirical accessibility is a good idea. I think by this he means making it work for real users. Fred Brooks’ ideas about the computer scientist as toolsmith seem very relevant.

I’ve been thinking about grass-roots accessibility for a while, though I can’t say I’ve made much progress. It seems to me we have to somehow empower people to enhance accessibility in a bottom up way without much help from developers.
