Abstract
This study investigates how emotionally engaging digital dolphin experiences may contribute to psychological wellbeing and tourism-related motivation. A digital dolphin observation application was developed in collaboration with the Echizen Matsushima Aquarium in Fukui Prefecture, Japan. The system integrates immersive dolphin video presentation, AI-based dolphin activity visualization, caretaker commentary, and interactive feedback functions designed to stimulate relaxation, curiosity, and emotional engagement. To examine the psychophysiological effects of the experience, this study employed a multimodal exploratory framework combining EEG analysis, subjective questionnaires, and cognitive-response assessment. Because EEG experiments require substantial preparation time and environmental control, the study was conducted as a pilot investigation involving ten participants. Two dolphin video conditions were prepared: a calm floating condition intended to induce relaxation and a dynamic movement condition intended to stimulate attentional engagement and curiosity. Experimental results indicated increased alpha-wave activity during dolphin observation, particularly under the calm floating condition, suggesting a relaxation-related neural response. Subjective evaluations also showed positive emotional reactions, including feelings of relaxation, enjoyment, and increased interest in visiting the aquarium. The findings suggest that emotionally engaging digital dolphin experiences may contribute to psychological restoration while also enhancing tourism-related emotional motivation. This study provides preliminary neurophysiological evidence supporting the potential of digital animal-based experiences within the emerging field of digital wellbeing tourism.
