Screen Magnification Software
Carol Karon’s Introduction to Screen Magnifier Software (in this case ZoomText) over at Yahoo! is well worth a viewing. Its interesting to observe the way she uses the software to interact with sites – particularly the various options and emphasis on different types of vision impairment and how they affect user interaction and user needs. I like these videos because they go farther than is possible in showing people the importance of high quality code and good interface design.
More Yahoo! Theatre videos are available on the Yahoo! User Interface Blog.
