ABSTRACT
Web applications facilitated by technologies such as JavaScript,
DHTML, AJAX, and Flash use a considerable amount of dynamic
web content that is either inaccessible or unusable by blind
people. Server side changes to web content cause whole page
refreshes, but only small sections of the page update, causing
blind web users to search linearly through the page to find new
content. The connecting theme is the need to quickly and
unobtrusively identify the segments of a web page that have
changed and notify the user of them. In this paper we propose
Dynamo, a system designed to unify different types of dynamic
content and make dynamic content accessible to blind web users.
Dynamo treats web page updates uniformly and its methods
encompass both web updates enabled through dynamic content
