"The new collaboration software enables users with low or no vision to report Web content accessibility issues they faced on specific Web pages. In addition, any Internet users who wish to aid in improving Internet accessibility can respond to such requests from visually impaired users by using the tool to contribute alternative text to solve the reported issue.
"How It Works
For example, a visually impaired individual wants to find out what image is showing. The image shows a photo of Mount Fuji taken during sunset. Existing screen reading software may not obtain the same information as shown in the image, or a description of the photo is simply missing. Whenever visually impaired users face such difficulties, they can report that incident by using the collaboration tool developed by IBM Research and ask for adding an improved alternative text to describe the image."
