couldn't find an url. -------- Original Message -------- Subject: Internet sonification browser makes web graphics more accessible Date: Wed, 10 Nov 1999 11:31:02 +0100 From: peter.b.l.meijer@philips.com Reply-To: uaccess-l@trace.wisc.edu To: <uaccess-l@trace.wisc.edu> Hi All, Currently a new web image sonification browser is under development, intended to make pure web graphics more accessible to totally blind users by sounding the content of GIF or JPEG images as "soundscapes". The user provides the URL of an image or a web page, and this results in a corresponding soundscape or a list of images and page links, respectively. In the latter case, the user can subsequently select and activate an image reference from the parsed HTML web page and get the soundscapes of that image. So one can either get the sound of an image directly through its URL, or indirectly by first having the sonification browser agent retrieve all image references from a web page URL and then selecting an image URL from the listed references. The software is meant for use in combination with a powerful screen reader such as Jaws for Windows or Window-Eyes. It depends on image complexity to what extent one will be able to learn to make sense of the often very complex sounds of images. Simple line graphs are among the most accessible image types. For instance, a web image of a sine wave plotted as a bright curve on a dark background will sound as a single tone going up and down in pitch as the curve is traced from left to right. For dark lines on a bright background one can apply the inverse video option to hear out the lines. The currently available browser features are described on the web page http://ourworld.compuserve.com/homepages/Peter_Meijer/eyebrows.htm The image sonification browser is an integral part of The vOICe Learning Edition "seeing-with-sound" software. That software is currently available for free for personal use, and user feedback on the new browser features is welcome. Note that the browser only sounds images, not the text of a web page. For reading the text of web pages you should use your screen reader in combination with a regular browser such as Netscape or Microsoft Internet Explorer. However, it is possible to synchronize your regular web browser with the sonification browser by optionally letting the sonification browser launch your default web browser on the very same URL that you pasted into the sonification browser dialog. Then the web page parsed for image files by the sonification browser will be the same as the one loaded automatically into your regular browser, and you only need to alt-tab among windows to manually switch between your regular Internet browser to read the text and the Internet sonification browser for hearing images. For discussion of details and experiences, you can subscribe to the seeingwithsound user group (mailing list) by sending a blank e-mail to seeingwithsound-subscribe@egroups.com With special thanks to David Poehlman and Unisys for arranging an LZW license for the built-in GIF image decoder, which forms a perfect example of how cooperation between users and developers can make a real difference.
