Recently, interest in AI technology products is increasing as the low birth rate and aging population increase. We have developed ‘Multi-Modal AI’ that monitors the health status (HR, HRV, respiration, sleep pattern, stress rate) of babies and the elderly in real time through vision AI and voice recognition technology, and determines intent through voice recognition. Unlike the initial model, emotional analysis through facial expression recognition of babies and the elderly and sleep pattern analysis through eye detection were added. AI digital healthcare improved through visual, auditory, and sensor data.
