Spontaneous behavioral coordination between pedestrians emerges through mutual anticipation rather than mutual gaze

Data file S1. Raw data for the body movement trajectories. This includes frame number, x and y coordinates (cm), and role ID in each row. The role ID is 0 if the individual is P2, 1 if the individual is P1 under the BASE condition, 2 if the individual is P1 under the NMG condition, and 3 if the individual is P1 under the NMA condition.

Data file S2. Raw data for the post-experiment questionnaire. This includes individual ID and ratings for NMA, BASE, and NMG conditions in each row.

Data file S3. Raw data for the P2’s gaze points on the video surface. This includes frame number, x and y coordinates (pixel), and individual ID in each row. The coordinate is (-1.0, -1.0) if data was lost. The origin of the pixel coordinates is the top left corner of the video surface.

Data file S4. Raw data for the P1’s head positions on the video surface. This includes frame number, x and y coordinates (pixel), and individual ID in each row. The origin of the pixel-coordinates is the top left corner of the video surface.

数据集S1：肢体运动轨迹原始数据。每一行包含帧编号、x与y坐标（单位：厘米）以及角色ID。其中角色ID为0时代表个体为P2；为1时代表BASE条件下的P1；为2时代表NMG条件下的P1；为3时代表NMA条件下的P1。

数据集S2：实验后问卷原始数据。每一行包含个体ID以及针对NMA、BASE、NMG三种实验条件的评分结果。

数据集S3：P2在视频画面上的注视点原始数据。每一行包含帧编号、x与y坐标（单位：像素）以及个体ID。若数据丢失，则坐标为(-1.0, -1.0)。像素坐标的原点为视频画面的左上角。

数据集S4：P1在视频画面上的头部位置原始数据。每一行包含帧编号、x与y坐标（单位：像素）以及个体ID。像素坐标的原点为视频画面的左上角。
