A dyadic fNIRS hyperscanning dataset for cooperative visuomotor control with haptic interaction

However, open hyperscanning datasets that combine interacting-brain recordings with synchronized kinematic and force measurements during cooperative visuomotor control remain scarce. Here, we present a functional near-infrared spectroscopy (fNIRS) hyperscanning dataset collected from 64 healthy adults organized into 32 dyads while they performed a virtual coloring task using two haptic-feedback devices.

Each dyad completed the task under two collaboration modes and two difficulty levels. In the leader-follower mode, one participant controlled the pen trajectory and the other controlled contact force, which determined brush width; in the egalitarian mode, the participants controlled orthogonal position components and jointly determined brush width. Task difficulty was manipulated by target-pattern complexity.
