Drag-and-drop graphic labeling items require users to click or touch and hold a label from one area of the screen while moving it into the selected location on an image elsewhere on the screen.
Drag-and-drop items require vision and motor skills to move elements on-screen. Text boxes may be confusing to screen readers. Audio files are not accurate after elements have been moved. Drag-and-drop items cannot be answered with a keyboard or switches. Moving parts cannot be represented in paper-and-pencil, braille, or optical scan test forms.
