Core Accessibility Principles

WCAG 2.1 Level AA compliance for presentations centers on four fundamental principles established by the W3C Web Content Accessibility Guidelines:

• Perceivable: Information must be presentable in ways users can perceive
• Operable: Interface components must be operable by all users
• Understandable: Information and UI operation must be understandable
• Robust: Content must be robust enough for interpretation by assistive technologies

For comprehensive understanding of WCAG principles, refer to the W3C WCAG 2.1 Guidelines and WCAG.com's practical guide for implementation details.

Essential WCAG Requirements for Presentations

While WCAG 2.1 contains 78 success criteria, presentations must focus on these three critical requirements that have the highest impact on accessibility:

1. Text Alternatives (Success Criterion 1.1.1)

• Requirement: All informative images must have descriptive alternative text
• AI Solution: Automated alt text generation using computer vision
• Implementation: Every chart, diagram, and informative graphic needs meaningful descriptions

2. Color Contrast (Success Criterion 1.4.3)

• Requirement: 4.5:1 contrast ratio for normal text, 3:1 for large text
• AI Solution: Real-time contrast analysis and automatic color adjustments
• Implementation: Text must be readable against background colors

3. Heading Structure (Success Criterion 1.3.1)

• Requirement: Logical heading hierarchy and proper slide titles
• AI Solution: Automated slide structure analysis and title suggestions
• Implementation: Each slide needs a clear, descriptive title

Research shows that five key accessibility issues account for 85% of barriers in presentations. Understanding these common problems and their AI-powered solutions helps you create truly inclusive content:

1. Missing or Inadequate Alt Text

The Problem: 67% of presentations have images without alternative text

Impact: Screen reader users can't understand visual content

AI Solution:

• Computer vision algorithms automatically generate descriptive alt text
• Context-aware descriptions that explain both content and purpose
• Real-time suggestions as you add images

2. Poor Color Contrast

The Problem: Low contrast between text and background colors

Impact: Users with visual impairments can't read content

AI Solution:

• Automated contrast ratio calculations
• Real-time warnings for insufficient contrast
• Suggested color palette adjustments

3. Missing Slide Titles and Poor Structure

The Problem: Slides without proper titles or logical content structure

Impact: Screen reader users cannot navigate effectively between slides

AI Solution:

• Automatic slide title generation based on content analysis
• Structural hierarchy suggestions for slide layouts
• Reading order optimization for complex layouts

4. Inaccessible Charts and Data Visualizations

The Problem: Complex data visualizations without text alternatives or screen reader support

Impact: Critical information remains inaccessible to users with visual impairments

AI Solution:

• Automated chart description generation explaining trends and key data points
• Data table alternatives for complex visualizations
• Voice-over friendly chart summaries

5. Lack of Keyboard Navigation Support

The Problem: Interactive presentations requiring mouse-only navigation

Impact: Users who rely on keyboard navigation cannot access interactive elements

AI Solution:

• Automated tab order optimization for interactive elements
• Keyboard shortcut suggestions for presentation navigation
• Focus indicator recommendations for better visibility

Google Slides Accessibility Features (2025)
