This study focuses on two significant social trends: the increasing proportion of solo eaters and the widespread use of technological products. It targets Generation Z to explore the synesthetic effects between screens, visual stimuli, and taste experiences when dining alone. The research employs eye-tracking technology as the primary experimental and analytical tool, conducting two phases of experiments: a quantitative questionnaire and an eye-tracking sensory experiment. The study analyzes the differences and correlations in eye-tracking metrics, such as gaze duration, attention ratio, and effective attention ratio, under conditions where visual and taste stimuli are similar or different. In addition to exploring the synesthetic effects between the visual content delivered by screens and the taste experiences during meals in the digital age, the study also investigates the expected emotional responses during dining, the variations in visual focus depending on eating styles, and media content preferences. Ultimately, the study aims to provide insights for future innovative design approaches to enhance the development and potential of solo dining experiences.
