In the digital age, people increasingly tend to hide their true selves on social media, virtual communications, and in the metaverse, using filters, avatars, and carefully crafted digital personas to create idealized versions of themselves. This concealment provides individuals with a sense of security and control, but also creates a disconnect between inner emotions and outward expressions. In this highly fluid information era, are we expressing our true selves or hiding them?This project aims to explore this social phenomenon by utilizing TouchDesigner and MediaPipe for real-time emotion visualization. The system detects users' facial expressions through MediaPipe and generates dynamic digital masks in TouchDesigner, artistically representing their emotional states. Unlike the filters on social media that enhance or beautify reality, this project seeks to reveal the emotions intentionally concealed, externalizing hidden feelings through abstract and fluid visual effects.
