We are constantly doing research on web technologies. Making better websites is the main goal of this research. By 'better' I mean web sites that are easier to use and accessible to all people, including people with disabilities. The W3C Standards have played a major role in the Web 2.0 craze. Many developers have changed the way they develop web sites based on these standards.

Typically, a blind person will access a website with a screen reader and hope that the developer has allowed for this in his / her design. As we speak special keyboards are being developed to help disabled people have easier access to the internet. ( Eric informed me of this technology. Maybe he can provide a link in the comments? )

Imagine a web site that speaks to you if you are blind, or a web site that allows you to control it through voice commands. Amazing right? This technology is upon us. Here is a link to a developer's site who has created a mixing board using this technology. All the sound is generated on the fly, no uploaded tracks, no uploaded mixes!

This also displays an amazing example of a tactile website. Which is only possible through Flash Technology. Here is an in-depth article about this technology:

If this technology can create sound with the click of a button... why not create sound based on text? An internal screen reader for the blind!

And, if that is possible, why not go a step further and capture sound, translate it into text. We could have voice controlled web sites or Closed Captioning for internet video!

This is the web we are working towards. The faster the internet becomes the closer we are to these types of Artificial Intelligence.

I find this very exciting. The possibilities are limitless! You're average web site will not exist much longer.
