Accessibility, Crowdsourcing and Human-Based Computation

Background

von Ahn, Luis; Ginosar, Shiry; Kedia, Mihir; Blum, Manuel (2006): “Improving Accessibility of the Web with a Computer Game (PDF)”, ACM CHI Notes 2006.
Note: access to Phetch, the program described in this paper, was discontinued in 2008.

Fix the Web (UK).
Fix the Web is a British initiative that relies on crowdsourcing for both reporting and fixing accessibility issues on websites. (Due to a redesign, registration as a volunteer is currently not possible.)
The EIII User Testing Tool is a bookmarklet that you can install in any JavaScript-enabled browsers in order to report accessibility issues that cannot be reliably detected through automated testing only.
The bookmarklet was developed during the European project European Internet Inclusion Initiative (EIII).

The following initiatives do not focus (or focus exclusively) on accessibility but have the potential to make sites more accessible.

Accessmonkey.
GreaseMonkey started as a browser extension for Firefox and a database of scripts. The scripts are bits of JavaScript that customise the way a webpage behaves or displays. They are created by volunteers, who upload them to a scripts database. Users can search the website or database and load scripts into the extension. The Greasemonkey extension also allows you to write your own scripts. (Forks and similar initiatives are listed further below.) If you want to learn more about Greasemonkey or start using it, the following websites are relevant:
- www.greasespot.net: the project's homepage.
- The Greasespot wiki explains how you can write scripts.
- The wiki page User Script Hosting explains where you can find scripts.
- User scripts are also available on the following sites: userscripts-mirror.org, openuserjs.org, greasyfork.org/en.
- The page Greasemonkey Hacks: Accessibility.
Scriptish is or was a fork of Greasemonkey. The project's code is available on GitHub. Note: the domain scriptish.org has expired.
SnipMatch is a search-based code repository. See also its Privacy page.
ShiftSpace was an open source metaweb or web annotation application and framework that was abandoned in 2011.
