Technology & Design in Partnership

Silicon Bay WAVE


The WAVE system has been designed with accessibility in mind from the outset, enabling visitors with a range of potential disabilities equal access to the website.


Why do websites have to be accessible?

  • It’s Law!
  • 14% of the UK are Registered Disabled
  • 4% of the UK have a Sight Problem
  • Download Speeds Increased
  • Better Search Engine Results
  • Easier to Maintain

The Law

In the UK it is unlawful for a service provider to discriminate against a disabled person by refusing to provide them any service which it provides to members of the public. As such, any website provided must also be accessible by customers with a range of potential disabilities:

  • 1995 Disability Discrimination Act
  • 1999 Disability Discrimination Act Part III
  • 2002 DDA Code of Practice, Part III


The W3C has produced a set of guidelines to produce accessible websites. WAVE has been designed with these standards in mind from the start:

  • Priority 1: Must be met
  • Priority 2: Should be met (EU recommended)
  • Priority 3: May be met to improve accessibility

America has the American federal accessibility standard - Section 508.

Alternative Browsers

As well as the standard computer web browsers, a web site should also be able to support a host of other browsers that may be used to view the site. WAVE websites can be viewed with the following browsers as well as the more common desktop browsers:

Text Only Browsers

e.g. Lynx: Can not display images, and have no table or multimedia support.

Screen Readers

e.g. Jaws: Typically used by the blind or partially sighted, reading the content in the order found in the HTML.


PDAs have small screens with limited support for JavaScript. It is estimated that there will be 58 million PDAs worldwide by 2008.

Web TV

Web TV supports a limited width of 560 pixels, with no horizontal scrolling.
