Study conducted to evaluate a method of testing web accessibility for people who are blind or have low vision who use a voice browser. Ten people participated in the study, and were asked to use Home Page Reader 3.01 from IBM to choose a required letter or number from lists on five different web pages. Each web page featured two different sequences of choice lists, as one list was presented in hierarchical order while the next was random. It is significant to note that the lists contained either two, three, four, five, or twenty-six characters. The participants were forbidden to use any visualization tools such as monitor displays, and were only aloud to use “Enter” or “Return” keys on their keyboards. Each participant repeated the task five times, while the required letter or number was randomly changed on each page. Statistical measures were used to differentiate between time taken to find the designated character in either random or hierarchical lists. Results indicated that web accessibility depended upon its hierarchical structure, particularly when the number of choice lists exceeds four. The quality of the choice lists was also found to affect site accessibility.
