Analyzing gaze and hand movement patterns in leader-follower interactions during a time-continuous cooperative manipulation task.

ABSTRACT: In daily life, people often interact by taking on leader and follower roles. Unlike laboratory experiments, these interactions unfold naturally and continuously. Although it is well established that gaze typically precedes object manipulation, much less is known about how gaze-hand patterns evolve in interactive settings where one person must take the other's actions into account. Here, we examine predictive, planning-related behavior in a two-player tabletop game called "do-undo." Participants alternated as Leader and Follower. The Leader performed simple pick-and-place actions to alter the arrangement of objects, while the Follower used other objects to restore the previous configuration. We recorded eye and hand movements, along with object trajectories, using a system that combined eye
