Methodology

Experiments were carried out in the laboratory of the Tourism College of Central South University of Forestry and Technology and in the meeting room of Changkou Village Committee. To avoid inaccurate eye tracking and EEG acquisition caused by the participants’ nervousness due to their unfamiliarity with laboratory instruments and the environment, and the influence of external factors, before the experiment the participants sat in a comfortable chair and wore the eye tracker and EEG detector at the same time under the guidance of researchers. They then adapted and rested for a certain period of time until the discomfort was eliminated. In addition, the experimental environment was controlled to be quiet, dimly lit with suitable for temperature and humidity [69]. In the experiment, eye movement calibration was carried out first, with the researcher instructing the participants to hold eye movement calibration cards for calibration; the experiment was carried out only after the calibration was completed. The experimental pictures were displayed in random order, and each picture was played for 10 seconds, so the participants only needed to watch freely according to their daily viewing habits [49]. The participants did not know the specific purpose of the experiment [70], and the experiment process was lengthy, allowing the participants to pause at any time and rest for five to 10 seconds before continuing [22, 71]. After the experiment, the participants need to fill in their personal details forms, and the researcher gave each participant a red envelope containing cash to express gratitude.
