Lawsuit seeks to improve Web access for the blind A ruling by a federal judge in San Francisco could mean that businesses and government agencies would have to make their Web sites accessible to the blind, something disability rights advocates say is vital as the routine transactions of everyday life take place increasingly on the Internet. U.S. District Judge Marilyn Hall Patel granted class-action status Tuesday to a lawsuit alleging that Target Corp. is in violation of California and federal laws because its Web site doesn't work with screen-reading software, essentially making the site unusable for blind people. To comply, Target would have to tag product images on its site with word descriptions, allowing the software to "read" those images aloud. Many retailers, including Wal-Mart Inc. and Amazon.com, have upgraded their Web sites or are in the process of doing so, said John Pare, executive director for strategic initiatives for the National Federation of the Blind. Most companies have done so voluntarily, he said, in response to concerns raised by the 50,000-member foundation.
