Profile Behavior#

  • Vision impaired: HUD scale, camera shake, reduced motion, readable font, letter spacing, and color palette.
  • Hearing impaired: captions, visual cue, haptic companion, HUD scale, reduced motion, and camera shake emphasis.
  • Motor impaired: one-handed controls, QTE alternatives, timing extensions, global game speed, and sequential combo input.
  • Cognitive: objective clarity, puzzle skip thresholds, adaptive difficulty, readable font, and letter spacing.
