Should not all Web sites accessible? You may be wondering why there is this problem and why all Web sites are no longer accessible to all users.There are a number of reasons I will present now.
Users visually disabled ranging from blind to completely blind color have problems with images that do not provide a textual description of what show. Without a description text users who cannot view an image has no way of knowing what is or what it represents.
These users also have problems understanding that logically are not created when “viewing” using a non-visual browser as a reader pantalla.Un screen reader is a browser that reads aloud Web sites to make Web sites accessible to users with visual disabilities. Often, a website that seems pleasant visually will be a complete disaster when it is heard through a screen reader.
Similarly to users with visual disabilities do not have any way of looking at an image, users with hearing disabilities have no way of understanding that communicates with sound, unless an alternative provided that does not use sound, such as a text description or image information.
If not are physically disabled, have you tried to use a website without the mouse?Unless you were lucky with the site that you choose Next, it was probably very difficult.Physical disabled users are often unable to use a mouse. unless these user requirements are taken into account when creating Web site navigation and physical disabled input method users will sometimes find a completely inaccessible website.
Web sites can be complex, and find the information you want can be difficult for the most capable of nosotros.Esto is not helped by sites that use a design too complex navigation that works differently in different pages (incoherent) and distracting animation repetitiva.Todos these problems are compounded for users with cognitive and neurological disabilities and this makes some completely inaccessible sites for them.
As we have seen, using the Internet if you have a disability can be a difficult task.To observe and understand the guidelines for designing accessible site Web can be produced that serves purpose and is accessible to all users, not only those without disabilities.
But does not stop there.Accessible Web design also has benefits for other usuarios.Vamos to see who can benefit.
The following groups will benefit follow the guidelines for accessible Web site:
Users of mobile phones, Web-TV and kiosks, low-bandwidth users, users in a noisy environment, users with “glow”screen, users that are driving users with a move access level, second language low literacy with different learning styles.
Related accessibility issues also improved:
‘Transmission and maintenance of the site, content andSearching content indexing machines.
There is another reason for its accessible (if you need more) Web site. According to figures current users currently disabled make up approximately 10% to 20% of the population in most of the países.Aumentar quantity of users divided into the categories above and is seeing up to 30% of the mercado.Si make your site accessible to 30% of the market not persuaded that accessible Web design deserves it, then, stop reading now.
It is also increasing the average age of the population in many países.Resultados in a number of issues of accessibility, including vision and hearing expiration changes and changes in the dexterity and the memory.if its market includes a significant number of users older can increase that 30% to a much higher percentage of users who will get the benefits of accessible Web design.
Address accessibility may be a requirement for certain websites, legal.Esto is normally for government sites, but may affect to others, each UK Web site must be accesbile discapacitados.Para discrimination act more information on the requirements in different countries see page W3C policies relating to the accessibility of the Web.
