Fig 1. Experimental setup and calibration.

(A) 10 right-handed healthy subjects performed 300 repeated trials of billiards shots in Embodied Virtual Reality (EVR). Green arrows mark the motion capture markers used to track and stream the cue stick movement into the EVR environment (B) Scene view in the EVR. Subjects were instructed to hit the cue ball (white), which was a physical ball on the table (in A), in attempt to shoot the virtual target ball (red) towards the far-left corner. (C) For environments calibration, MoCap markers were attached to the HTC Vive controllers which were placed in the pool-table’s pockets with additional solo marker in the cue ball position.
