Accessibility -

- Accessibility is essential for promoting equitable access to education and ensuring that all learners have the opportunity to succeed.

- Inclusive design considers diverse user needs, including visual, auditory, cognitive, and motor impairments, to ensure that instructional content and activities are designed to accommodate these needs.

- Interactive design principles, such as intuitive navigation, clear visual hierarchy, and interactive feedback, can enhance accessibility by providing multiple modes of engagement and accommodating different learning styles and abilities.

- As an interactive design student, you're familiar with the importance of creating engaging and user-friendly digital experiences. In the context of instructional design, accessibility is a critical component of creating effective interactive learning environments.

Interactive Design:

Relation to

The acronym “ADDIE” stands for Analyze, Design, Develop, Implement, and Evaluate. It is an Instructional Design model that has withstood the test of time and use. It is simply a “device” to help us think through a course's design.


Accessibility Fundamentals Overview on W3.ORG

WCAG Guidelines: Adhere to the Web Content Accessibility Guidelines (WCAG) to ensure that digital content meets accessibility standards.


It is crucial to adhere to the following underlying principles:- Perceivable:

  • Information and user port components must be presented so users can perceive them.
  • Provide text alternatives for non-text content.
  • Offer alternatives for time-based media, such as captions for videos.
- Operable:
  • All piloting and interactive elements must be practicable and usable by all users.
  • Ensure keyboard accessibility for all interactive elements.
  • Provide time for users to read and terminated tasks.
- Understandable:
  • Information and procedure of the user port must be extremely clear and straightforward.
  • Use uniform navigation and clear language.
  • Provide input assistance to facilitate users avoid and correct errors.
- Robust:
  • Content must be robust enough to be interpreted reliably by a wide change of user agents, including assistive technologies.Use valid and semantic HTML.

Alistair Duggin, Head of Accessibility at GDS, explains the four 'POUR' principles of accessibility. Services have to be: Perceivable, Operable, Understandable, Robust.

Web accessibility principles examples:

It’s important to make buttons, links and controls large enough so that people with motor impairments can use them. Small controls, or controls that are placed too close to each other are difficult for many people to use. It’s best to not demand precision from your user and give all clickable elements space. This is especially relevant on mobile and tablet devices with smaller screens.

Large links,

Closed captions describe all dialogue and sounds and in video audio. People often confuse subtitles with closed captions, but they are slightly different. Closed captions provide a text alternative in the same way subtitles do, but they include other relevant sounds (like “Door knocks”) in the video.

on videos

Closed captions

Websites should have a good colour contrast between text and background colour. That includes links, icons, buttons and any other information on the page. An example of poor colour contrast is light grey text on a white background.

Colour combinations with

Good Contrast

- Clear and Concise Language: Use language that is easy to understand and free from jargon to accommodate diverse learners. - Visual and Auditory Elements: Include visual aids and auditory cues to cater to different learning preferences and abilities. - Keyboard Navigation and Screen Reader Compatibility: Ensure that content is navigable using keyboard inputs and compatible with screen reader software for accessibility.



In corporate training, accessible design fosters an inclusive learning environment and improves employee engagement. For instance, an e-learning module can feature clear navigation menus, audio descriptions for visual content, and keyboard shortcuts for ease of navigation. Examples of accessible design features benefiting employees with disabilities, such as customizable font sizes, high-contrast themes, and audio descriptions for video content. Positive impact on employee performance and satisfaction, leading to increased productivity and retention rates.

Application in

Corporate Training

In higher education, accessibility is crucial for ensuring equal access to educational resources for all students. For example, an online course platform can incorporate accessibility features such as closed captioning for lecture videos, keyboard navigation, and descriptive alt text for images. Examples of accessible design features benefiting students with disabilities, such as screen reader compatibility, text-to-speech functionality, and simplified navigation structures. Benefits of inclusive design for all learners, including improved usability, comprehension, and engagement.

Design: Creating accessible design solutions entails incorporating features that accommodate users with disabilities without compromising the user experience.

- Development: Implementing accessibility features involves coding and designing interfaces to comply with accessibility standards such as WCAG.

- Implementation: Applying accessibility principles in work settings requires integrating accessible design practices into various projects, including those in higher education and corporate training.

- Evaluation: Assessing the effectiveness of accessibility initiatives involves measuring user satisfaction, compliance with accessibility standards, and improvements in user accessibility.

  • Essential for
    • People with low vision or a visual impairment
    • Certain people with colour deficiencies who may struggle to distinguish between certain colours.
  • Useful for
    • Elderly people and anyone over the age of 50, as the colour contrast sensitivity in our eyes naturally declines with age.
    • People with temporary disabilities, like cataracts
    • People in different lighting conditions, for example, experiencing glare on a mobile phone screen in bright sunlight.
    • Everyone, including those with non-specific visual conditions. That’s why the most popular, legible colour combination is dark text on a white background.
  • Note, people with dyslexia or migraine sensitivity may prefer lower colour contrasts. That’s why it’s important to let users change the contrast between background and text.
  • Essential for
    • Deaf people
    • People who have a hearing impairment
    • People with cognitive impairments or learning difficulties, who may use captions to help them understand video content.
  • Useful for
    • Elderly people affected by hearing loss
    • People with Attention Deficit Hyperactivity Disorder (ADHD), who may use captions to help them focus.
    • Users who experience sensory overload or migraines, who may prefer to watch videos without sound.
    • People with hearing loss
    • People watching videos in a loud, public environment, like a bus. Or people watching in a silent environment, like a library.
    • People who use English as a second language
  • Essential for
    • People with motor impairments or reduced dexterity. This includes people with Cerebral Palsy and conditions like Parkinson’s and motor neurone disease.
  • Useful for
    • Blind and visually impaired users
    • Elderly people
