Usablenet Text Transcoder (or transcoder) is a web application that converts a web page into its text-only version on-the-fly by eliminating all page layout that is present in the original page and by hiding many accessibility defects.
The transcoder is useful for the website visitor, since it removes some accessibility issues and small defects such as missing image ALTs, forms that are not properly linearized or flash objects. It also provides some navigation options that are not usually available on browsers and that improve the user experience of disabled users or users of mobile technology.
How Lift Works
To transcode a page Usable has to (Figure 1):
- Receive a request from the visitor's browser,
- Issue a request to the webserver hosting the site,
- Wait for the webserver and the network to yield the data,
- Transform the page, and finally
- Send the transformed page to the user's browser.
