Autonomous driving increases the risk of motion sickness. Flowing Landscapes takes passengers on a mindfulness virtual journey through the beauty of traditional Chinese landscapes, integrating peaceful landscape aesthetics with mindfulness techniques to reduce motion sickness during travel. The system incorporates an adaptive mechanism that responds to physiological signals, dynamically adjusting visual stimuli to further minimize discomfort. We tested 4 conditions by varying input adjustments and collected psychological and physiological data from the participants (N = 20). The experimental results indicate that biofeedback reduces motion sickness, while the landscape meditation environment enhances user immersion and pleasure. This study highlights the potential of combining cultural aesthetics, mindfulness, and adaptive features to create a more comfortable in-car VR experience, with future work focusing on further personalization based on individual biofeedback.
