EIZO Releases Color Vision Deficiency Simulation Monitor

EIZO has created a monitor that can simulate various types of vision deficiencies (PDF document). It is great to see hardware vendors making an effort to provide tools to improve accessibility, but this one makes me wonder. Do you really need to have hardware support for this? The advantage seems to be that you can test moving images more easily.

EIZO worked closely with the Color Universal Design Organization (CUDO) (also see english machine translation) in conducting experiments with colorblind test subjects to improve the ability to identify difficult to distinguish colors.

Fore those not fortunate to have access to an EIZO monitor, there are a number of software tools available to simulate how web pages and images look with various types of vision deficiencies:

What I haven’t seen is an application that isn’t confined to the browser, but works on top of your operating system. I guess this wouldn’t be very hard to do. Depending on the operating system it should be possible to have a filter applied to the entire screen. If you know of one, please post it in the comments below.

Automated Accessibility Tests with RAAKT in Ruby on Rails

A couple of days ago I released RAAKT – The Ruby Accessibility Analysis Kit gem (I know, it really needs a better name). RAAKT is a gem that can be used independently of Rails and my plan was to make a Rails plugin that would add a custom assert method that did the check. It turns out that it only takes five lines of code so there is no need for a plugin. So let’s see how you can integrate accessibility checks into your current Rails application.
