Gesture-Based Unlock Pattern Where a Simpler Input Would Work
2.5.1 — Pointer Gestures
Scenario
Setting
A webinar platform's registration form
What’s wrong
Signature/gesture unlock patterns where the *function* isn't essential to be path-based.
Example
On a webinar platform's registration form, a visitor hits this wall: signature/gesture unlock patterns where the *function* isn't essential to be path-based.
Why it matters
People with limited hand mobility and users of head-pointers, sticks, or eye-gaze systems. On a webinar platform's registration form, this barrier means they can't operate the feature without a mouse.
How to test
Check whether a gesture-based unlock/signature pattern is genuinely essential to the function (e.g., an actual signature) or just used for an ordinary action that could be a button: the latter fails.
How to fix
A single-tap/click alternative must exist for every path-based or multi-point gesture.
Outcome
Corrected, a webinar platform's registration form now lets a visitor complete the task using only the keyboard.
Who is affected
People with limited hand mobility and users of head-pointers, sticks, or eye-gaze systems.
