Web Accessibility Initiative

The tools and techniques for addressing issues related to the blind are very different from those designed to solve problems of color blindness. Perhaps the more diverse the category of cognitive impairment. This group includes people with epileptic disorders and people with disabilities associated with learning and development. This type of users often rely on special hardware and software to access Web content. These tools, known as assistive technologies, ranging from screen readers to touch screens and head pointers. The analysis of some of these devices, both hardware and associated software, are the centerpiece of the article The Web Accessibility (Part 2): Assistive Technologies. A crucial aspect of its operation is to operate on suitable content to be read and processed so unconventional.

It is the responsibility of the designers make this possible. Other limitations: temporary disability and age to these categories should be added temporary disability. Imagine a person with a broken wrist prevents him from properly handle the mouse and is required to use the web to their daily work. It is equally important to remember that as they grow older the chances of seeing affected by a disability. In fact, almost 75% of the population over 80 years suffer any deterioration in its capabilities. Therefore, accessibility is not a matter of opening the doors to these people but to keep them open.

Accessibility provides a level of independence that age could make the somewhat difficult. Additionally, these web sites will allow users to full capacity the full access to content regardless of the user application to use (standard browser, voice browser, text browser, mobile phone, etc..) And environmental constraints in which it operates (noisy or silent, below or above lit rooms, hands-free environment, etc.).. Web Accessibility Initiative (WAI Web Accessibility Initiative): A Way Web Accessibility Initiative of the World Wide Web Consortium is a definitive way when facing the challenge of accessibility. In that connection has issued a recommendation called Content Accessibility Guidelines web explaining how to make accessible the contents of the Web to people with disabilities. The document contains an appendix that structures all the points that should be taken into account when developing a Web site organized as checkpoints by topic and priority, understanding images, multimedia, tables, frames, forms and scripts. Each of the 14 guidelines of accessibility guidelines is associated with a level of priority: o Priority one includes actions that designers “should” take to a site accessible. o Priority 2 includes shares that designers “should” take to a site accessible. o Priority 3 represents the actions that designers “can” take to improve the accessibility of a site. Priority points one lay the foundation for accessibility standards in virtually all countries that have adopted a formal policy of accessibility.
