Welcome in Everyone! Since reading on digital rhetoric from week 8, have you been consciously looking for the use of digital technology such as hyperlinks or videos that engage the audience while on different web sites; or have you used this technology within your own web page. This week we will be discussing Web Accessibility. Having an accessible website that is user friendly by people with disabilities means to have your design deliver inclusive experiences for everyone. This involves developing content that users with visual, physical, and cognitive limitations can interact and navigate. To ensure your website is in compliance of web accessibility, you should follow the Web Content Accessibility Guidelines (WCAG). These guidelines were set by the World Wide Web Consortium (W3C). They provide a structure for creating websites greater accessible for people with disabilities.
WCAG has four principles that form the foundation of web accessibility. These four principles are Perceivable, Operable, Understandable, and Robust (POUR). Let's discuss these key principles in detail. Perceivable means the information must be introduced in a way that users can recognize. As a content creator you should provide text alternatives for non-text content, like using videos, icons, audio, and images. These alternatives offer a visual rather than text. Operable means the content should be functional. The user should be able to interact freely using different methods, like user interface should be accessible through keyboard and time friendly to read content. Understandable means the user should be able to comprehend the interface. This would include making text understandable and operate in predictable ways. So, avoid using jargon and complex terminology. Robust means having content strong enough to be interpreted by a variety of user agents, this includes assistive technologies. Examples of assistive technologies would be any software or equipment that maintains or improves the capabilities of the disability community. This could be voice recognition software or text-to-speech programs. Also, this means updating digital resources to ensure compatibility with different assistive technologies and ensures accessibility as technology evolves.
WCAG has three levels of compliance. All websites should strive to meet at least level A, which is the minimum of the accessibility guidelines. This is the foundational level of conformance. The creator should provide alternative text for images. Level AA is the most common and builds upon Level A. Level AA address common barriers such as, allowing text to be resized up to 200% without loss of function and allowing various modes to navigate the content.While Level AAA is the peak and most challenging level of conformance accessibility, it requires meeting Level A, AA, and AAA criteria. An example would be offering extended audio descriptions for videos and sign language interpretation for all pre-recorded audio. Level AAA is not needed for the entire website, just where it can be applied as some criteria can not meet all content.
Making digital content more accessible can make the experience better for everyone. "Finding ways to be better and contribute to a more accessible world is part of what I call "being a good citizen of the world" (Driscoll et al., 2022). I hope this helps you create a more usability and web accessible website. I wish this course material had been introduced earlier in the semester, that way I could have been more aware. I have provided the link below to the WCAG checklist summarized by Yale University for your toolbox.

Question of the week😊
Before reading this content, did you look for accessibility conformance when viewing a website?
