The Convention on the Rights of Persons with Disabilities and their optional protocol were approved on December 13, 2006 at the United Nations headquarters, as an instrument for the social development of people with disabilities and indicates that access to information and communication technologies should be found within the reach of all People.

On May 30, 2011, the General Law for the Inclusion of Persons with Disabilities is created, which indicates in its article 32 that:

people with disabilities have the right to freedom of expression and opinion; including the freedom to collect, receive and provide information through any form of communication that facilitates a participation and integration in equal conditions as the rest of the population. For such purposes, the competent authorities will establish among others, the following measures:

  1. facilitate in a timely manner and without additional cost, the information aimed at the general public, in accessible formats and with the technologies appropriate to the different types of disability;
  2. Promote the use of Mexican sign language, the Braille system, and other modes, means and communication formats, as well as access to the new systems and technologies of information and communications, including the Internet;
  3. The media and private sector institutions that provide services and provide information to the general public, will provide it in accessible formats and easy to understand people with disabilities.

    Likewise, on April 30, 2014, the National Program for Equality and Non-Discrimination 2014-2018 was published in the Official Gazette 2014, in which it is established in Strategy 1.3:

    1.3.4. Accessible.

    On December 3, 2015, the agreement that establishes the general provisions of web accessibility that must observe the dependencies and entities of the Federal Public Administration and the productive companies of the State, where the application of the most up-to-date international accessibility elements of the W3C must be Minimum.

    Web accessibility initiative (WAI)

    in the accessibility standards of accessibility , which could be summarized in equal opportunities and access to people with temporary or permanent disabilities, regardless of their equipment, language. Mobility or cognitive skills. Perhaps we could further summarize the concept A, applications made for all.

    to exemplify some points that we must consider when a web application is developed, we can mention:

    • alternative text for images. The alternative text will be available for those with visual weakness who are helped by screen readers who cannot know the content of an image, but are also commonly occupied by some mobile browsers for data transfer savings in mobile networks.
    • keyboard or mouse as an input device. Not all users can use the mouse or keyboard as devices to interact with the computer, for this reason navigation and data capture in web applications must solve more than a mode of interaction.

    • These are examples that you will find in the 12 guidelines that the standard has, which are organized in 4 principles: perceptible, operable, understandable and robust. Each of them are evaluated to achieve a level of implementation cataloged in A, AA and AAA.

      Now it only remains to apply what we have learned, we share a couple of links where you can find broader explanations to the aforementioned concepts, reference guides and evaluation tools:
