Accessibility in audio visual designs has become imperative to meet compliance standards and for inclusivity. Integrating the right features helps people with disabilities experience technology on equal terms. This ensures no one feels excluded from communications, programs or events. As AV technology evolves, incorporating accessibility should be a key consideration. This blog discusses some best practices for incorporating accessibility features.
Understanding Accessibility Needs
Start by learning the types of disabilities users may have:
Visual impairments - low vision, blindness requiring audio
Hearing impairments - deafness needing visual cues
Physical disabilities - limited mobility, dexterity issues
Cognitive disabilities - processing information differently
Research standards like ADA, WCAG for designing inclusive experiences. Conduct accessibility assessments and user testing early in the design process.
Universal Design Principles
Adopt universal design thinking to create solutions usable by all without adaptation:
Equitable use - Appeal to varied skills and abilities
Flexibility in use - Accommodate individual preferences
Simple and intuitive design - Minimal memorization
Perceptible information - Present across senses
Tolerance for error - Minimize dangers and consequences
Low physical effort - Minimal fatigue over long periods
Appropriate size for approach - Usable regardless of body size
This ensures equal access through empathy and thoughtful design.
Captioning and Transcripts
Provide:
Real-time captioning for audio streams like presentations
Offline automatic captioning/transcription for videos
Human captioning for accuracy in critical contexts
Synchronized captions for any device playback
This makes audio content accessible through multiple modalities.
Audio Description
Describe visual elements like:
Actions occurring onscreen
Scenes, locations being shown
Characters and faces being introduced
Through supplemental audio tracks or videos to aid comprehension for low vision/blind users.
Sign Language Interpretation
Include:
On-screen American/International sign language interpreters
Pre-recorded signing videos for self-paced navigation
Live remote interpreting arrangements if possible
To communicate and translate spoken dialogue for the deaf community.
Control Systems
Implement:
Software/hardware controls for accessibility functions
Simple user interfaces with large hit targets
Consistent navigation across pages/devices
Keyboard access for non-mouse users
Ensures equal control over technology without assistive devices.
Color Contrast
Follow:
WCAG color contrast ratio guidelines for text/images
Compatible high contrasts for low vision accessibility
Color blindness simulation while selecting palettes
To make visual elements legible to varied vision capabilities.
Multi-Modal Delivery
Present information through:
Text summaries for deafblind populations
Speech output, tactile overlays for visual content
Automated captions, audio for visually impaired
Signing/description hybrids for varied needs
Unified solutions cater to combined disabilities through layers.
Responsive Design
Apply:
Flexible formats for small/large displays
Customizable subtitles,audio/visual controls
Intuitive zoom/magnification for mobile use
Consistent navigation on varied input methods
Ensures anytime, anywhere accessibility ubiquitously.
Supportive Technologies
Integrate or pair solutions with:
Screen readers like JAWS, NVDA to access interfaces
Braille displays, refreshables for tactile content
Hearing tech - induction loops, infrared systems
Mobility aids - wheelchairs, walkers
Leverages adjunct devices seamlessly.
User Testing
Obtain iterative feedback from:
Accessibility experts, advocates for standards
Users with diverse disabilities, assistive tech needs
Focus groups from targeted demographics
Usability labs for realistic environment testing
Refines experiences through lived expertise and perspectives.
Resources and Evaluation
Some best practices are:
Partnering with accessibility consultants
Training employees,evaluating awareness
Budgeting for continual improvement initiatives
Accessibility standards compliance monitoring
Third party tech, design evaluations
Solidifies commitment through practices beyond minimum compliance.
Many solutions exist to make experiences inclusive through technology when implemented intentionally. By adopting user-centered design principles and working closely with representative communities, audio visual designers can create solutions that empower and connect all.
