In this study, we investigated the impact of perceptual and emotional changes associated with field-of-view (FOV) expansion during straight-line walking on the gait of pedestrians. We developed an interactive FOV expansion system that varies FOV with the walking speed of pedestrians and compared it with walking under conditions where the FOV remains constant. The results of the experiments revealed that pedestrians who prefer walking at relatively fast speeds exhibit gait changes resembling brisk walking to maintain a broad FOV. On the other hand, pedestrians who prefer a leisurely pace tend to adopt a wide and cautious gait to avoid excessive or insufficient FOV expansion.
Furthermore, in the former group, an increase in dynamism, openness, novelty, and enjoyment during walking was observed, along with a notable shift in post-walking mood towards an activated direction. These findings suggest the potential for interactive FOV expansion during physical activity to exert effects akin to mental doping. In the future, our objective is to optimize the system and explore suitable control methods for adjusting the presented FOV. Simultaneously, we aim to narrow down the triggering conditions for the effects induced by FOV expansion and strive to enhance the generalization performance.
