The World Wide Web has rapidly become the dominant Internet tool, combining hypertext and multimedia to provide a network of educational, governmental, and commercial resources. The Web has mushroomed in popularity because it is such a powerful and versatile medium. Much of its power comes from the fact that it presents information in a variety of formats while it also organizes that information through hypertext links. Because of the multimedia nature of the Web combined with the poor design of some Web sites, many Internet surfers cannot use the full range of resources this revolutionary tool provides.
Some people use adaptive technology with their computer to access the Web.
A person with a mobility impairment may not be able to use a mouse and rely on the keyboard for Web browsing. They should consider the special needs of individuals with disabilities, older persons, people for whom English is a second language, and those using outdated hardware and software. Universal design techniques can be applied in the design of packaging, software, appliances, transportation systems and many other products and services. Examples of universal design in architecture are the inclusion of ramps and automatic door openers as well as Braille labels on elevator control buttons. Following universal design principles in creating a Web resource ensures that all Internet users can get to the information at a Web site regardless of their abilities, their disabilities, or the limitations of their equipment and software.
