Abstract: Disclosed herein is an interaction monitoring system, comprising an environment collection module, interaction monitoring module, interaction segmentation module, and display module. The environment collection module detects surrounding environment and generates a data stream. The interaction monitoring module generates a feature data stream by extracting feature value of the data stream. The interaction segmentation module determines a target situation, which indicates a user's state or condition, from the feature data stream and generates a target image or video stream, which indicates the target situation. The display module displays the target image. Other embodiments are described and shown.
