Diagram Editor Where Nodes Connect Only by Dragging

2.5.7 — Dragging Movements

Scenario

Setting

A food-delivery app's order-tracking screen

What’s wrong

Drag-to-connect diagram/node editors with no click-source-then-target alternative (where dragging isn't essential).

Example

Consider a food-delivery app's order-tracking screen: drag-to-connect diagram/node editors with no click-source-then-target alternative (where dragging isn't essential).

Why it matters

People with limited dexterity and switch, eye-gaze, or voice users who cannot drag. On a food-delivery app's order-tracking screen specifically, they get stuck and can't reach the control.

How to test

Try connecting nodes in a diagram/flow editor via click-source-then-click-target instead of dragging: if drag is the only method (and isn't essential to the function), it fails.

How to fix

A single-pointer, non-dragging alternative (buttons, menu option, tap) must exist for the drag operation.

Outcome

Fixed, a visitor to a food-delivery app's order-tracking screen can reach and operate the control without a mouse.

Who is affected

People with limited dexterity and switch, eye-gaze, or voice users who cannot drag.
