Two-Finger Gesture Required With No Single-Pointer Option
2.5.1 — Pointer Gestures
Scenario
Setting
A pharmacy app's prescription-refill form
What’s wrong
Two-finger pan/rotate requirements without single-pointer controls.
Example
Here's what happens on a pharmacy app's prescription-refill form: two-finger pan/rotate requirements without single-pointer controls.
Why it matters
People with limited hand mobility and users of head-pointers, sticks, or eye-gaze systems. Here, on a pharmacy app's prescription-refill form, the result is they can't operate the feature without a mouse.
How to test
Try the two-finger pan/rotate action with a single finger or a button instead: if no single-pointer alternative exists, it fails.
How to fix
A single-tap/click alternative must exist for every path-based or multi-point gesture.
Outcome
After the fix, the same visitor to a pharmacy app's prescription-refill form can now reach and operate the control without a mouse, specifically for the “Two-Finger Gesture Required With No Single-Pointer Option” issue on a pharmacy app's prescription-refill form.
Who is affected
People with limited hand mobility and users of head-pointers, sticks, or eye-gaze systems.
