Tools and requirements

Test procedure
Use various input mechanisms (cursor, keyboard, screen reader) to navigate to a CAPTCHA and interact with it. Identify what senses (sight, vision) the CAPTCHA requires by default and observe if there is an option for an alternative.
- CAPTCHAs must have two different modalities of interacting with the test.
- Commonly, you'll have a vision test paired with an auditory test.
- All CAPTCHA modalities must allow the user to achieve the same thing.
