Web Accessibility for Persons with Motor Limitations

Abstract

Nowadays the internet is an important medium for serving people. Using the internet can help people completing several tasks and accessing different types of information (e.g., reading news, finding location for places, buying and selling products online, and so on). Accessing the internet is not an easy task for people with motor disabilities. The main barriers come from two issues: difficulty or inability in using the mouse and difficulty or inability on typing on the keyboard. The web accessibility guidelines are a set of suggested techniques to be used by web developers when designing, implementing, and maintaining websites to make them easy to access by people with disabilities. This chapter presents the importance of applying web accessibility standards and guidelines when designing and developing web pages. These guidelines are obtained from Web Content Accessibility Guidelines 2.0 (WCAG), section 508, and other literature. The challenges and barriers encountered by people with motor disabilities when they use the web are presented. Then, different techniques that can be used by web developers to ensure the accessibility of websites for people with motor disabilities are introduced. At the end a discussion on evaluating and testing the website conformance to the web accessibility standards and guidelines is presented. Several evaluation techniques that can be used for web accessibility evaluation is introduced and explained to clarify the process of web accessibility testing.
