We would like to congratulate Yunhe Feng for having his paper SenCAPTCHA: A Mobile-First CAPTCHA Using Orientation Sensors published at UbiComp 2020. SenCAPTCHA is a mobile-first CAPTCHA system that works by displaying an animal picture to the user and having them rotate their phone to move a ball into the center of the animal’s eye. The results of a user study with 200 participants showed that SenCAPTCHA outperforms other existing CAPTCHAs and that it was the favorite CAPTCHA system for over half of participants.
