Pain measuring device and pain measuring method

A pain measuring device comprising:

• a plurality of Peltier elements;
• a camera;
• a sensor;
• a memory in which at least one instruction is stored;
• and
• a processor configured to execute the at least one instruction,
• wherein, by executing the at least one instruction, the processor
• controls a temperature provided from the plurality of Peltier elements,
• receives a user input for recording a level of stimulation according to the temperature,
• obtains, from the camera, image data representing a change in an external shape of a user according to the stimulation,
• obtains, from the sensor, biodata representing a biological change of the user according to the stimulation, and
• obtains information about a level of pain experienced by the user according to the stimulation by inputting data corresponding to the user input, the image data, and the biodata to a trained neural network model,
• wherein the plurality of Peltier elements comprises a plurality of first Peltier elements grouped into a first group and a plurality of second Peltier elements grouped into a second group,
• wherein the plurality of first Peltier elements are arranged to form a different geometric pattern from the plurality of second Peltier elements, and
• wherein the processor controls the plurality of Peltier elements to provide different temperatures through the first group and the second group, enabling the user to recognize the geometric pattern formed by the plurality of first Peltier elements.
