ABSTRACT
People often use computers other than their own to access web content, but blind users are restricted to using only computers equipped with expensive, special-purpose screen reading programs that they use to access the web. Web-Anywhere is a web-based, self-voicing web browser that enables blind web users to access the web from almost any computer that can produce sound without installing new software. The system could serve as a convenient, low-cost solution for blind users on-the-go, for blind users unable to afford a full screen reader and for web developers targeting accessible design. This paper overviews existing solutions for mobile web access for blind users and presents the design of the WebAnywhere system. WebAnywhere generates speech remotely and uses prefetching strategies designed to reduce perceived latency. A user evaluation of the system is presented showing that blind users can use Web-Anywhere to complete tasks representative of what users might want to complete on computers that are not their own. A survey of public computer terminals shows that WebAnywhere can run on most.
