(Left) Example target trajectories. (a) The target in the Linear Smooth Pursuit task moves in straight lines of random direction and distance. (b) The target in the Arc Smooth Pursuit task moves in circular lines of random direction, distance, and curvature. Both pursuit tasks feature only a single target. (c) Each of the three targets in the Rapid Visual Search task starts some distance from the participant and moves towards the participant. (d) In the Rapid Visual Search Avoidance task there are three targets to fixate on (blue) and three blocking targets to not fixate on (yellow). Each target and blocking cube starts from a plane some distance from the participant and moves towards the participant. The dashed line represents a horizon. (Right) Orientation of the frames used by the VIVE Pro Eye headset to define head and eye orientations. The head vector is defined with respect to the world frame, and the eye vectors are defined with respect to the head frame which is attached to and follows the VR headset. Target trajectories of each of the four tasks.
