Case study: Investigate

On this page, we describe how we applied the investigation phase of the Natively Adaptive Interfaces (NAI) approach to a specific use case: making online videos accessible for users who are blind or low-vision (B/LV).

Define users and identify needs

In this phase of the process, we focus on identifying our target users and delving into their specific needs, pain points, and behaviors:

  1. Define your target users and the problems to solve.

    • Target users:
      • Edge user: fully blind, since birth
      • Users across the range of visual abilities:
        • Fully blind, acquired during lifetime
        • Legally blind, since birth
        • Legally blind, acquired during lifetime
        • Low vision, since birth
        • Low vision, acquired during lifetime
        • Sighted
    • Identify the design challenge:

      Make watching online videos, such as tutorials, entertainment, and news, fully accessible and engaging for people who are blind or have low vision.

  2. Understand user needs, pain points, and behaviors.

    • Feedback from blind users revealed the following significant challenges with online videos.
      • Activating accessibility features: enabling essential features such as screen readers is often difficult, frequently requiring assistance from a sighted person.
      • Navigating playback and app settings: Interacting with video controls—play, pause, rewind, etc.—and application settings—dark mode, playback speed, etc.—remains challenging, even when accessibility tools are active.
      • Inaccessible visuals: Without access to visual content, blind users only get the audio track, often leading to a critical loss of information and context.
