Accessibility Scope Viewer

Accessibility Scope Viewer (PN)

Accessibility Scope Viewer (PN) is a tool designed to help designers and developers understand how user interface (UI) elements are interpreted by screen readers through the accessibility tree.

What It Does

The Accessibility Scope Viewer (PN) allows users to:

  • Visualize the accessibility information associated with UI elements, such as roles, labels, and states.
  • Understand the hierarchical structure of UI elements as presented to assistive technologies.
  • Identify accessibility gaps, such as missing labels or incorrect semantic roles.

Key Features

  • Element-by-element preview: Click on any UI element to view its screen reader-accessible metadata.
  • Role hierarchy view: Explore how UI roles and landmarks are organized in the accessibility tree.
  • Live overlay: Display accessibility information directly on top of the UI elements.
  • Audit insights: Highlight issues like missing ARIA roles, low contrast, or incorrect labeling.
  • Compatibility mode: Simulate how different screen readers (e.g., NVDA, JAWS, VoiceOver) interpret content.

Integration Possibilities

  • Can be developed as a browser extension similar to Chrome DevTools’ Accessibility pane.
  • Potential integration with design platforms like Figma through plugins.
  • Usable in automated testing pipelines for accessibility audits and compliance tracking.
