Recognition system employing thermal sensor

A gesture recognition system, comprising:

• a thermal sensor configured to acquire and output a thermal image with a first field of view;
• an image sensor configured to acquire and output an image frame with a second field of view;
• and
• a processor configured to determine a processed region in the thermal image, and perform a gesture recognition only according to an image region in the image frame corresponding to the processed region in the thermal image.

A medical monitoring system, comprising:

• a wearable accessory, comprising:
• a thermal sensor configured to measure a body temperature;
• and
• a transmitter configured to send a temperature message of the body temperature and a label message of the wearable accessory;
• and
• a central computer system configured to
• receive and store the temperature message, and
• provide a warning message associated with the label message when the body temperature indicated by the temperature message exceeds a predetermined range.

A body temperature monitoring device, comprising:

• a wearable accessory configured to be worn on a human body;
• a thermal sensor disposed in the wearable accessory, and configured to measure a basal body temperature of the human body;
• a display disposed in the wearable accessory, and configured to prompt an ovulatory phase;
• and
• a processor disposed in the wearable accessory, and configured to
• record the basal body temperature every day, and
• control the display to prompt the ovulatory phase when a temperature variation of the basal body temperature exceeds a temperature variation threshold.
