Background

• Downloading of music and videos from the Internet has become incredible popular!

• Can systems for downloading these files be used by people with disabilities?

• Idea:– Study two of the most popular systems.– What are the strengths and weaknesses in the

accessibility of each system?

Accessibility

• Describes to what degree a system is usable for as many people as possible without modification.

• Computer users are getting older…

• Assistive technologies.

The Pirate Bay

• “The world's largest BitTorrent tracker”.

• In January, 2007 the worlds 268th most visited web site with 1 418 296 registered users.

• Many torrents points to copyrighted material.

• Free of use.

The iTunes Store

• The first really successful online digital music store.

• Started by Apple computers in 2003.

• Over 3.5 billion songs sold and a market share of 88% in the US.

• Offers download of music, video and audio books.

• Operating system– Microsoft Windows XP Professional SP2.

• Web browsers– Microsoft Internet Explorer 7.0.5730.11– Mozilla Firefox 2.0.0.1– Opera 9.10

• BitTorrent clients– uTorrent 1.6, English version– Opera 9.10

• Screen magnifier– Microsoft magnifier

• Screen reader– JAWS v7.10.452

Result:

– The Pirate Bay possible to use thanks to the simple design and the use of valid XHTML.

– The iTunes Store is impossible to use.• “iTunes is one of the most difficult pieces of software to

use. This is because it uses non-standard windows controls to display and manage items, and so screen reading technology does not stand a chance of reading the screen contents. Even the application's menu bar is inaccessible” (Brian Hartgen, 2007)

Summary of the result
