In Echoes of Specters, Ding Shiwei creates a circular interactive video installation featuring 30 AI-generated simulated arm images produced by ChatGPT-4. When viewers approach the screens, ultrasonic sensors trigger the static arm images to transform into generative AI animations, making the arms flutter like fabric or flags. The installation creates a ghostly plaza where the specters refer not only to the complex AI systems but also to the users hidden behind ideological images.
