This project is a CAPTCHA-like authentication system where the user is shown an emoji and must mimic the same facial expression in front of their camera to pass the verification. Regular CAPTCHAs are tedious. emoCAPTCHA makes verification playful by asking people to mimic emojis. Beyond fun, the goal is societal benefit: modern AI still struggles with reading human emotions, and ethically sourced examples of real facial expressions can help improve that. If users choose to contribute, their emoji-matching selfies could form a valuable dataset to train models to better understand human emotions.
