Part of the 'AI:More than Human' exhibition 2019 at Barbican Through a series of questions, making viewers realize how big of a footprint they have left on the internet. The project is built using WebGL combined with face detection. With detection of the looking direction of the face, we could also detect whether the viewer is nodding or shaking their head. And then we invite the views to nod or shake to answer the question. Progressing through the questions, if the user has left more footprints on the internet, it makes the face more visible.
