ROOT proposes a new coexistence model for a climate-challenged Earth, emphasizing AI-human collaboration. It centers on three components: an AI companion robot, an inflatable AI tent, and XR camping experiences. Users travel with the robot, utilizing XR glasses to transform real environments into surreal virtual landscapes. The AI tent offers a multi-sensory environment via spatial audio and 3D content. ROOT ultimately shows the potential for a New Ecology where humans, AI, and nature forge a symbiotic future.
