Noonchee-VX is a life-saving AI co-pilot for autonomous vehicles, designed to transform robotaxis into mobile first responders. Equipped with multimodal sensors, it continuously and non-invasively monitors passengers for acute medical emergencies such as heart attacks, asthma, or sudden loss of consciousness. By analyzing vocal tone, gaze direction, facial color, sweating, and other biometric cues in real time, the system identifies early warning signals with high precision. Its disease-specific models, trained on extensive hospital and public clinical data, reach up to 92% accuracy with an F1 score of 0.89. When a critical event is detected, Noonchee-VX autonomously reroutes the vehicle to the nearest emergency room, securely transmits vital data to first responders, and provides passengers with calm, empathetic voice guidance. Running on edge AI, it ensures core sensing, inference, and navigation functions even without LTE/5G connectivity. More than conversational support, its core mission is safeguarding lives in driverless mobility.
