Accessibility approach and limitations

Accessibility features and known limitations in the public SafeSpark™ Variant Demonstration Hub.

Public development demonstration using fictional school and learner data

Features present in this build

  • Keyboard and touch navigation.
  • Skip links, landmarks and visible focus indicators.
  • Read-aloud, pause, resume, stop and replay controls where the lesson engine provides them.
  • Chunked lesson presentation and clear next-step controls.
  • Different explanation methods, confidence checks and reduced-information options.
  • Responsive mobile and tablet layouts.
  • Reduced-motion behaviour.
  • Text alternatives for VexSpark™ images and generated diagrams.

Known limitations

  • Formal independent accessibility conformance testing has not been completed.
  • Screen-reader behaviour must be checked across NVDA, VoiceOver and TalkBack.
  • Spanish and French mixed-language pronunciation needs specialist review.
  • Generated mathematical diagrams need human review for complex notation and long descriptions.
  • Physical installed-App testing remains required.

Accessibility position

4P3X SafeSpark™ is being developed towards strong accessible-design standards. Formal independent accessibility conformance testing remains part of production readiness.

No WCAG certification or independent conformance claim is made.

Adaptive next-step support

4PEX AI™ Easy Path

Every learner version now keeps a labelled “Do this next” control visible inside the lesson portal. It can focus the answer field, select a suitable explanation method, move to the next question, return to unfinished practice or guide the learner to the confidence check.

  • Uses explicit text as well as visual highlighting.
  • Can favour really-easy, visual, example-led or step-by-step explanations.
  • Never autoplays speech; read-aloud still requires a learner action.
  • Respects reduced motion and preserves keyboard focus.
  • Does not diagnose a learning need or replace specialist accessibility assessment.
