可访问性和可用性是用户界面和网站的既定概念。可用性是精确定义的，但有不同的方法来实现可访问性。此外，残疾人和非残疾人用户遇到的问题之间可能存在不同的关系，但在这个问题上几乎没有收集到经验数据。网站的可访问性和可用性准则提供了问题对用户重要性的评级，但几乎没有收集到实证数据来验证这些评级。一项研究调查了两个网站的可访问性，其中有6名残疾人（盲人）和6名非残疾人（盲人）。这两个小组遇到的问题包括两组相互交叉的问题，大约有15%的重叠。对于这两个网站中的一个，盲人对问题的评分明显高于视力正常的人。与会者之间有很高的协议，以问题的严重性，与会者和研究人员之间的协议。然而，无论是参与者或研究人员之间没有显着的协议和无障碍性和可用性指南提供的重要性/优先级评级。这些结果的实际和理论意义进行了讨论。
Accessibility and usability are well established concepts for user interfaces and websites. Usability is precisely defined, but there are different approaches to accessibility. In addition, different possible relationships could exist between problems encountered by disabled and non-disabled users, yet little empirical data have been gathered on this question. Guidelines for accessibility and usability of websites provide ratings of the importance of problems for users, yet little empirical data have been gathered to validate these ratings. A study investigated the accessibility of two websites with 6 disabled (blind) and 6 non-disabled (sighted) people. Problems encountered by the two groups comprised two intersecting sets, with approximately 15% overlap. For one of the two websites, blind people rated problems significantly more severely than sighted people. There was high agreement between participants as to the severity of problems, and agreement between participants and researchers. However, there was no significant agreement between either participants or researchers and the importance/priority ratings provided by accessibility and usability guidelines. Practical and theoretical implications of these results are discussed.
