Wearable electronic device and emotion monitoring method

A wearable electronic device, comprising:

• a physiological data monitoring sensor configured to acquire current physiological state data of a wearer in real time;
• a data memory having stored thereon physiological state data of the wearer in a preset emotional state, wherein the preset emotional state is a stable emotional state where the physiological state data of the wearer is within a normal physiological state data range;
• a processor configured to:
• compare the current physiological state data acquired by the physiological data monitoring sensor with the physiological state data of the wearer in the preset emotional state, to determine whether or not the wearer is currently in the preset emotional state, thereby to acquire a first comparison result;
• generate an emotion monitoring output instruction based on the first comparison result;
• detect an image outputting device within a predetermined distance from the wearer and separated from the wearable electronic device;
• and
• transmit based on the emotion monitoring output instruction when the first comparison result indicates that the wearer is currently not in the preset emotional state, an output filtering instruction to the image outputting device detected by the processor, wherein the image outputting device filters out texts and pictures containing predetermined emotionally adverse information during displaying a content, based on the output filtering instruction;
• and
• wherein the processor is further configured to adjust a display color of the image outputting device into a warm tone based on the emotion monitoring output instruction when the first comparison result indicates that the wearer is currently not in the preset emotional state.
