Abstract: A method and system for detecting short-term stress of a subject person and generating alerts in an indoor environment are disclosed. The system may receive data on the subject person's heart rate, galvanic skin response, and accelerometer movement from a wearable device, and also capture image frames through a camera. After that, the system may perform bio-signal analysis in accordance with the heart rate and the galvanic skin response data, and perform skeletal motion analysis in accordance with the image frames. Based on bio-signal index and skin conductance index generated from the bin-signal analysis and skeletal motion analysis respectively, the system may perform data fusion to determine the short-term stress.
