Question
Digital accessibility means a website or computer program is designed to be used by a wide range of users, including those that may have visual, auditory, motor, or cognitive disabilities. Users with special needs may not be able to easily read text on a screen, hear a video narration, type on a keyboard, or use a mouse.
The Web Content Accessibility Guidelines or WCAG 2.0 are widely used by websites to help ensure pages are usable by most users. The WCAG 2.0 guidelines are based on 4 principles:
Principle 1: Perceivable - Users must be able to obtain (perceive) information
Principle 2: Operable - Users must be able to use (operate) navigation and other user interface components
Principle 3: Understandable - Users must be able to understand the information presented
Principle 4: Robust - Content must be compatible with assistive technologies (e.g. screen readers)
Read through the WCAG guidelines for each principle by clicking on the link below.
Notice that each principle has many guidelines to deal with different situations. For example, under Principle 1, point "1.1.1 Non-text Content" says, essentially, that non-text content should have alternative text descriptions. Can you envision how this would work on a web page? If you have an image, for example, that image might be accompanied by a text description of the image. That way, someone who has vision difficulty can use a screen reader to hear the text description and understand (or perceive) what is in the image.
For each of the 4 WCAG principles, select one specific point underneath a guideline (e.g. "1.1.1 Non-text Content") and briefly describe the problem in your own words. Also, try to guess how the recommended solution might assist readers. List the point you selected and your description in the text areas below.
This is a teacher-graded exercise.
1. Principle 1 (Perceivable) - Which specific guideline did you select? Explain the problem and solution in your own words. Can you guess how this solution will help users?
2. Principle 2 (Operable) - Which specific guideline did you select? Explain the problem and solution in your own words. Can you guess how this solution will help users?
3. Principle 3 (Understandable) - Which specific guideline did you select? Explain the problem and solution in your own words. Can you guess how this solution will help users?
4. Principle 4 (Robust) - Which specific guideline did you select? Explain the problem and solution in your own words. Can you guess how this solution will help users?
