Accessible Player Controls

When thinking about player controls, designers must consider different user needs and the variety of devices they use:

• Remote Buttons and D-pad Navigation: On platforms with remotes that have dedicated buttons, controls like Fast Forward (FF), Rewind (RW), and Play/Pause should be prioritized for easy navigation. However, on platforms with simpler remotes, designers should rely on the d-pad for content navigation and interaction with playback features.
• Alternatives to Press-and-Hold: Many users with motor disabilities find “press-and-hold” interactions difficult. Offering alternatives like single-tap or d-pad controls provides a more inclusive experience.
• Timeline Navigation with TTS: Rethinking timeline interaction allows Text-to-Speech (TTS) to offer more useful feedback. Designing with TTS in mind lets screen readers give real-time updates about a user’s position within the video.

Closed Captioning (CC) and Customization

Closed captions are critical for users with hearing impairments, and designers should focus on making them easy to customize:

• Use OS-based Settings: Whenever possible, apps should respect system-level closed caption settings, allowing users to fine-tune caption preferences like color and size. This not only enhances accessibility but also ensures consistency across all apps.
• Minimize In-app CC Settings: If system-level settings are in place, in-app closed caption settings may be unnecessary. Reducing in-app options helps streamline the user interface, making the player easier to use.

Audio Description (AD) Support

Ensuring that Audio Descriptions (AD) are widely supported across platforms is crucial for blind or low-vision users:

• Universal AD Support: While many platforms already support AD, designers should strive for universal support across all platforms. Making AD easy to enable and ensuring its availability on all content enhances accessibility for all users.
• Licensing and Availability: Supporting AD often requires coordination with content providers, as it involves licensing negotiations. Designers should advocate for broader availability of AD tracks to make more content accessible.

Text-to-Speech (TTS) and Screen Reader Support

Designing with TTS and screen reader support ensures that users with visual impairments have a seamless experience:

• Native, OS-level Synthetic Voices: Ensure that TTS supports native voices and multiple languages. It’s also important to provide controls for adjusting speaking rates and verbosity settings. Platforms like tvOS and Android TV allow users to reduce the amount of information spoken by screen readers, which is particularly helpful for experienced users.
• Relative Volume: TTS should integrate well with other audio elements, allowing users to control the volume. Features like relative volume, where the playback audio lowers as TTS speaks, should be supported across all platforms to enhance usability.

Additional Language Support

Offering multi-language support ensures a more inclusive video player design:

• System-level Language Settings: When users change the OS language, all elements of the video player—such as visuals, audio, captions, and TTS—should automatically switch to match the selected language. This creates a cohesive experience.
• App-level Language Options: In addition to system-level settings, apps should provide language options to switch captions, audio, and TTS within the app itself. This allows users more flexibility without needing to adjust their entire system language.

Audio Adjustments for Accessibility

Designers can enhance the audio experience for users with hearing impairments or sensory sensitivities by providing flexible audio settings:

• Advanced Audio Processing: While many platforms offer basic volume leveling or dialogue enhancement, AI-based audio processing could take this further. By enhancing dialogue clarity or reducing loud sounds, designers can create a more comfortable listening experience for all users.
• Pre-processing Audio Tracks: Pre-processing audio tracks with AI can ensure that dialogue remains clear while minimizing sudden loud noises, especially on platforms that don’t support built-in volume adjustments.

Epilepsy Considerations

For users with photosensitive epilepsy, designers can help prevent seizures by incorporating AI-powered tools:

• AI-powered Flashing Light Detection: While Apple’s tvOS dims the screen when flashing lights are detected, it has limited effectiveness. Designers can enhance this by using AI to detect flashing lights ahead of time, automatically dimming or blacking out the screen during these scenes. This proactive approach offers better protection for epileptic users.

Conclusion: Video Accessibility Design

Designing for video accessibility requires a deep understanding of user needs and a commitment to inclusion. By focusing on player controls, supporting TTS and AD, and integrating AI-powered features, designers can create video players that truly serve everyone. With thoughtful design, video accessibility can move beyond compliance and deliver a richer, more enjoyable experience for all users.

AI Pre-processing for Epilepsy and Trigger Warnings

One area that has seen significant potential for accessibility improvement is video content for users with epilepsy. Apple’s tvOS was an early innovator, implementing screen dimming to mitigate flashing lights that could trigger seizures. However, this hardware-based approach is limited. AI-powered pre-processing could elevate this solution, allowing real-time detection of flashing lights and automatically dimming the screen during those scenes. This would provide more accurate and comprehensive protection for epileptic users.

Additionally, AI could improve the overall user experience by tagging content with trigger warnings for scenes with flashing lights, intense violence, or other potential triggers. This gives users a better understanding of the content they are about to watch, enhancing safety and comfort.

Enhancing Audio for an Accessible Video Player

For users with hearing impairments or sensory sensitivities, audio accessibility is paramount. While some platforms—such as Apple’s tvOS, Roku, and LG—include basic volume leveling or dialogue enhancement features, there’s still room for improvement. Leveraging AI pre-processing could offer more advanced audio adjustments. For example, audio tracks could be pre-processed to:

• Reduce loud sounds that might startle or discomfort users.
• Enhance dialogue clarity for those with hearing impairments, ensuring critical information is always audible.

In platforms that don’t natively support detailed audio adjustments, these pre-processing techniques would allow engineers to build in audio optimization without requiring system-level integration.

Video Quality and Bandwidth Flexibility

Video quality settings are typically available across most platforms, offering users the ability to choose between 720p, 1080p, or HDR depending on their bandwidth. However, adding more control over video quality can improve accessibility for users with limited bandwidth or metered internet connections. This control would allow users to choose a resolution that best suits their needs without consuming excessive data.

For users who are blind or have low vision, an innovative feature would be to include a “no video” option, allowing users to enjoy the audio content alone, further reducing data usage. This would cater to both accessibility needs and bandwidth constraints, ensuring a seamless experience for all users.

Integrating Mobile Apps for Enhanced Controls

Many connected TV (CTV) apps lack complex controls due to the limited functionality of traditional remotes. To address this, engineers could integrate CTV controls into mobile apps, allowing for more customizable, resizable remotes that include:

• Advanced shortcuts for ease of navigation.
• Synchronized audio experiences for Audio Descriptions (AD) and multi-language support.
• Voice control or eye-tracking technology (like Apple’s upcoming feature for iOS 18), enabling users with mobility impairments to navigate the platform effortlessly.

By connecting mobile apps to CTV experiences, developers can offer users more complex interactions in a more accessible format without cluttering the main app interface. Additionally, there’s potential to open-source mobile app remote control APIs, encouraging the industry to adopt these features and promote better accessibility interactions across platforms.

Accessible Video Player Ads: A Missed Opportunity

Current advertising in video apps often lacks adequate accessibility features. For example:

• Text-to-Speech (TTS) rarely announces the number of ads queued, time remaining in ad breaks, or other relevant information.
• Many apps fail to include Closed Captions (CC) for ads, leaving deaf users without access to the content.

Moving forward, it’s crucial that ad content partners adopt accessibility standards for ads. A simple solution would be to require TTS to announce the number of ads and total duration when entering an ad break. Additionally, CC should be mandated for all ads to ensure consistency across content and maintain a high level of accessibility throughout the viewing experience.

Conclusion: Engineering an Accessible Video Player with Purpose

Building accessible video platforms requires thoughtful engineering and a commitment to inclusion. By implementing AI-powered pre-processing for video and audio, providing more flexible control options, and enhancing the ad experience, engineers can create a more inclusive environment for all users. Accessibility isn’t just a feature; it’s a necessity that allows everyone to engage with the content they love, no matter their abilities.

1. Playback Speed Controls

One of the most underutilized features in video players is playback speed control. While some platforms offer the ability to adjust playback speed, this feature isn’t universally embraced or fully optimized. Allowing users to modify playback speed without distorting audio pitch benefits a diverse range of viewers.

For instance, those who need to quickly catch up on content can speed up the playback without missing important details, while others who require more time to process information can slow it down. Playback speed control also increases ad consumption opportunities, benefiting platforms. By making this feature intuitive and customizable, video players can cater to different user needs and establish it as a standard feature.

2. Ad Accessibility

Despite being a significant part of video content, ad accessibility remains a major gap. Most platforms lack basic accessibility features for ads, such as closed captions (CC) and Text-to-Speech (TTS) announcements. Without these tools, people with disabilities miss essential information.

To improve ad accessibility, video platforms should ensure that:

• Closed captions are consistently available for all ads, just as they are for regular content.
• TTS announcements communicate important details like the number of ads queued, the total duration of the ad break, and how long until the program resumes.

By implementing these features, platforms can provide a smoother ad experience, reduce frustration for users with disabilities, and create a more inclusive advertising environment.

3. Native System Integrations

Many video apps miss the opportunity to fully integrate with native, system-level features like virtual keyboards, voice search, and accessibility settings (CC, AD, TTS). Platforms like tvOS have earned praise for accessibility, but many tvOS apps often lack consistency when used on non-tvOS devices.

For a more seamless experience, video players should:

• Leverage native virtual keyboard integration, allowing users to use platform features like voice input for searching and typing. This reduces cognitive load and enhances accessibility for users with physical disabilities.
• Ensure consistency in using system-level settings for CC, AD, and TTS across platforms, so users don’t need to adjust their preferences in each app.

By prioritizing native integrations, video players can offer a more cohesive experience across devices, making content more accessible for everyone.

4. Background Video Playback

Picture-in-Picture (PiP) functionality can be helpful for many users, but it presents challenges for individuals with motor disabilities. Navigating between foreground content and PiP windows can be difficult and confusing, making it less accessible.

A better alternative for connected TV apps is background video playback, especially for Electronic Program Guides (EPG). This feature allows users to continue watching content in the background while navigating menus or guides, providing a smoother viewing experience without overwhelming the interface.

However, it’s crucial to give users control over this feature. They should have the option to disable background playback, or at least mute the audio, ensuring the experience remains flexible and user-friendly.

Conclusion: Video Accessibility Innovation

As the video streaming industry continues to grow, companies must prioritize video accessibility innovation at every stage of design and development. Addressing overlooked concepts like playback speed controls, ad accessibility, background video playback, and native system integration will create a more inclusive and user-friendly experience for all viewers.
