What is Web Accessibility ?
Web Accessibility: Dear friends, I am landing here with some of my thoughts about the Website/Electronic content accessibility. This is like a " B ‘day and B ‘day Cake “which everyone should celebrate and taste it or "It is mandatory for all agencies to make website usable for all type of users"
I have work out on web accessibility and got lots of information this is pretty well term to access website or electronic content for physically challenged peoples. This is basically an amendment by US Government how to make our electronic content accessible which comes under section 508.
In August 1998 Us Government passed one law for electronic content accessibility, which is really helpful for disable, younger, older age internet users. It help the other users also whose are temporary disable (Slow internet connection, lack of devices etc.) It's really emphasized the user to access the content fast as everyone expect. We can use progressive enhancement also to access usable content from the internet, which is really helpful for all type of users.
Understanding the Four Principles of Accessibility:
The guidelines and Success Criteria are organized around the following four principles, which lay the foundation necessary for anyone to access and use Web content. Anyone who wants to use the Web must have content that is:
1. Perceivable - Information and user interface components must be presentable to users in ways they can perceive.
o This means that users must be able to perceive the information being presented (it can't be invisible to all of their senses)
2. Operable - User interface components and navigation must be operable.
o This means that users must be able to operate the interface (the interface cannot require interaction that a user cannot perform)
3. Understandable - Information and the operation of user interface must be understandable.
o This means that users must be able to understand the information as well as the operation of the user interface (the content or operation cannot be beyond their understanding)
4. Robust - Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.
o This means that users must be able to access the content as technologies advance (as technologies and user agents evolve, the content should remain accessible)
If any of these are not true, users with disabilities will not be able to use the Web.
I will be back with my next article for you with some technology of information accessibility, how to make it for our Websites.
Will be back soon !!!
