| Outline of Annual Research Achievements |
The project is advancing steadily, and we have acquired valuable findings. Specifically, we have continued our examination of the impacts of social interactions on pedestrian dynamics. Additionally, we have conducted thorough analyses of collision avoidance behaviors during encounters involving individuals and pairs. As a result, we have initiated research into the spontaneous synchronization of gait among socially interacting pairs, an area showing promising initial results which will require further exploration.
Concurrently, we have executed an experiment to explore how target shape affects smooth pursuit. Moreover, we have outlined plans for additional experiments to consolidate our findings. This research constitutes a critical step towards devising effective methods to nudge pedestrians.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
Analysis of collision avoidance behaviors:
Our investigation into collision avoidance behaviors during encounters involving individuals and two-person groups has progressed significantly. The findings from our studies were presented at the Pedestrian and Evacuation Dynamics (PED) conference in 2023, and the corresponding article is under review for publication in Collective Dynamics. In addition, we have carefully analyzed the differences in behavior between individuals and groups of two during these encounters scenarios, and we plan to submit these results for publication soon. Furthermore, we have started studying the spontaneous gait synchronization among socially interacting two-person groups, which represents a promising avenue for further exploration.
Experiment on the impact of target shape on smooth pursuit:
Our experiment examining the influence of target shape on smooth pursuit has been successfully designed and executed with an initial group of participants. We are currently in the process of analyzing the results, and we have outlined plans for additional experiments to validate our findings. This research holds potential for enhancing our understanding of how target characteristics affect tracking performances.

| Strategy for Future Research Activity |
My research plan includes two main objectives:
Nudging of pedestrians: I propose conducting complementary experiments to examine how pedestrians respond to different types of tracking target. Specifically, we aim to include a broader demographic, particularly focusing on the elderly population. By studying their smooth pursuit of various targets, this analysis will provide valuable insights into the effectiveness of nudging strategies and inform the development of tailored interventions to enhance pedestrian safety and mobility.
Analysis of pedestrian behaviors: Our research will keep investigating pedestrian behaviors during encounters, with a focus on avoidance strategies and the influence of social interactions. Additionally, we plan to study spontaneous gait synchronization among pedestrians, specifically exploring how the intensity of interaction affects synchronization patterns. Understanding these dynamics will inform crowd management techniques and urban design strategies.
