“…According to the research results of Constantin et al (2021) and Natarajan et al (2005), the degree of interest represents the interest weights of subjects in different regions of interest, and the larger the weight, the higher the interest of subjects in a scene or a certain region [ 41 , 42 ]. In this study, the degree of interest is calculated according to the subjects’ gaze time and pupil diameter in the digital landscape roaming immersive experience [ 43 , 44 ], as follows:

In this study, the virtual engine software (Unity 2019, Unity Software Inc., San Francisco California, American) was used to generate a digital landscape model, forming a virtual immersive environment. Through field investigation and emotional preference experiments, the ancient tree ecological area and the sunlight-exposed area were respectively monitored, and the somatosensory comfort evaluation model was established. The subjects showed the highest degree of interest in the ancient tree ecological area after landscape roaming experience, and the mean variance in SC fluctuation was 13.23% in experiments. The subjects were in a low arousal state and had a significant degree of interest in the digital landscape roaming scene, and there was a significant correlation between positive emotion, somatosensory comfort and the Rating of Perceived Exertion index; moreover, the somatosensory comfort of the ancient tree ecological area was higher than that of the sunlight-exposed area. Meanwhile, it was found that somatosensory comfort level can effectively distinguish the comfort level between the ancient tree ecological area and the sunlight-exposed area, which provides an important basis for monitoring extreme heat. This study concludes that, in terms of the goal of harmonious coexistence between human and nature, the evaluation model of somatosensory comfort can contribute to reducing people’s adverse views on extreme weather conditions.
