Operable
WCAG 2.5.1
Pointer Gestures
Anything that uses a complex gesture — pinch-to-zoom, swipe along a path, two-finger rotate — must also work with a single tap or click. Maps, sliders, and carousels are common offenders. Affects people who can't make precise movements.
In plain terms
Anything needing a complex gesture — pinch, or swipe along a path — must also work with a single tap, for people who can't do fiddly movements.
Why this matters
Path-based or multi-finger gestures — swipe-along, pinch, two-finger rotate — are impossible for many people using a switch, head pointer, or single finger. They need a plain single-tap alternative.
How to detect
Quick check
List every gesture-driven feature (maps, sliders, swipe carousels). Can each be operated with a single tap or click instead? If a complex gesture is the only way, it fails.
