Accessibility of CAPTCHA

Sunday, 10th September 2006

Summary

Completely Automated Public Turing test to Tell Computers and Humans Apart (CAPTCHA) is a technique that attempts to differentiate between humans and machines on ability alone. Whether it's sensory, mobility, or cognitive ability, testing the user's ability will always create barriers that are insurmountable to some people, particularly when you consider than many people with sensory impairments rely on machines such as screen readers to overcome their sensory impairments.
