Abstract:

Try your ordinary web browsing and e-mail with an translucent piece of plastic draped over your monitor, with your monitor partially obstructed, or with your monitor turned off. With each of these changes, you’ll have a significantly different experience. For example, if you have plastic draped over your monitor, you’ll likely have a hard time reading words, interpreting graphics, or distinguishing colors. If your monitor is partially obstructed, you’ll likely have a difficult time navigating pages, reading columnar formats, or associating graphics with text. And, of course, if your monitor is off, you’ll have an entirely different set of challenges in accessing and using information. Each scenario offers a different view of the information onscreen, poses different challenges, and, most important, each is significantly different from unimpaired viewing.
