ALPACA is a camera-only software that estimates user satisfaction (UX) from users' facial emotional dynamics. It extracts a valence–arousal time series from RGB frames using a Facial Emotion Recognition module and computes features over time windows. It supports identity-free (default, privacy-by-design) and context-aware (optional, with metadata to improve robustness) modes. Designed to also run on-device without saving videos, storing only anonymized descriptors if required.
