Which example best illustrates Path-Dependent Input in accessibility testing?

• A. Dragging and dropping content with a mouse
• B. Typing a password
• C. Selecting from a long dropdown with keyboard
• D. Drawing with a mouse, which would require an unreasonable amount of keyboard input to compare

Answer: (B)

Path-Dependent Input refers to interactions where the result depends on following a specific sequence or route through the interface, not just performing a single action. Typing a password fits this well because authentication hinges on entering a precise sequence of keystrokes in the correct order, with each character shaping the final credential and the overall login outcome. This linear, step-by-step input is exactly what keyboard users and assistive tech rely on to complete the task. The other examples either involve a direct mouse action or require navigating a list, which don’t depend on a strict sequential path to achieve the goal in the same way.
