Shifting the Focus: Exploring Video Accessibility Strategies and Challenges for People with ADHD

Research Background and Issues

• Identified Problems and Challenges:
  • Although video as a medium is increasingly popular, many videos remain unfriendly and inaccessible to individuals with Attention Deficit Hyperactivity Disorder (ADHD). Current research on video accessibility primarily focuses on blind/low-vision or deaf communities, with limited exploration of the accessibility needs of ADHD populations.
  • The attention, engagement, and information retention abilities of individuals with ADHD are easily influenced by the visual and auditory elements of videos. Features such as flashing lights, slow speech rates, and inconsistent audio-visual content can lead to either overstimulation or insufficient sensory input for ADHD viewers.
• Significance:
  • ADHD affects nearly 400 million adults globally (approximately 6.76%), making it a highly prevalent neurodiversity phenomenon. Videos play a critical role in education, social interaction, and entertainment, so improving the video-watching experience for ADHD users carries broad social significance.
• Research Motivation and Related Work:
  • Individuals with ADHD are more likely to experience interruptions in video viewing due to distractions, overstimulation, or sensory overload. While existing studies suggest that captions and audio descriptions can help improve information retention and attention, these studies are often limited to single platforms or specific video types.
  • Current accessibility guidelines (e.g., Web Content Accessibility Guidelines, WCAG) do not provide explicit design recommendations for ADHD users.

Solution

• Proposed Solution:

  • Conduct semi-structured interviews to gather insights into ADHD users' viewing habits, current strategies, and preferences for accessibility features.
  • Develop ADHD-inclusive design principles and provide specific design recommendations for video platforms and content creators based on user feedback.

• Innovative Contributions:

  • Systematically uncovered the specific frustrations and coping strategies of ADHD users during video viewing.
  • Proposed a video accessibility design framework tailored to ADHD users (e.g., dynamic captions, personalized audio tracks, chapter markers).
  • Emphasized personalization and flexibility, advocating for platforms and creators to address issues of overstimulation and understimulation.

• Implementation Steps and Key Techniques:

  • Research Methodology: Conduct online interviews with 20 self-identified ADHD participants to observe their specific video-watching behaviors.
  • Analyze the data to summarize ADHD users' video accessibility needs, including preferred and frustrating content.
  • Derive design recommendations suitable for ADHD users from the results, covering technologies such as audio adjustments, customizable captions, and dynamic pacing controls.

Research Outcomes

• Specific Findings:

  • Identified major challenges in video viewing for ADHD users: difficulty concentrating or maintaining attention, challenges in long-term information retention, and discomfort caused by overly complex platform interfaces.
  • User strategies included using captions to process auditory information, adjusting video playback speed, and using timestamps for quick navigation.
  • Proposed accessibility features desired by users, such as customizable audio tracks, video summaries, and simplified interface designs.

• Advantages Over Existing Solutions:

  • Compared to existing research, this study encompasses the universal needs of multiple video types (educational, social, entertainment) and platforms, rather than focusing on a single use case.
  • Highlights the diversity and unique needs of ADHD users, contributing to the design of more inclusive solutions for the neurodiverse community.

• Experimental and Evaluation Results:

  • All participants indicated that current platform functionalities are insufficient to meet the accessibility needs of ADHD users.
  • ADHD users expressed a strong preference for greater functional flexibility, such as dynamic caption style options, finer speed adjustments, and chapter markers.
  • There is a high practical demand for accessible video content, especially in educational and information consumption contexts.

• Limitations and Future Directions:

  • Limitations:
    • The study did not implement specific prototype designs, making it impossible to directly evaluate the effectiveness of particular accessibility mechanisms.
    • Primarily observed individual video-watching behaviors without delving into the dynamics of social content sharing or group viewing.
    • The sample was limited to adult ADHD users, excluding minors or older adults.
  • Future Directions:
    • Develop prototype video interfaces for user testing.
    • Investigate ADHD video behaviors in relation to age, social contexts, and multitasking scenarios.
    • Study conflicts between platform algorithms and user attention management, proposing more responsible commercial design models.

Through this study, the authors not only identified the barriers faced by ADHD users in video viewing but also provided actionable design guidelines, advancing the field of multimedia research for neurodiversity adaptation.
