Decision-making is an essential part in basketball offenses. In this paper, we proposed a basketball offensive decision-making VR training system. During the training, the trainee can intuitively interact with the system by wearing a motion capture suit and be trained in different virtual defensive scenarios designed by professional coaches. The system will recognize the offensive action performed by the user and provide correct suggestions when he/she makes a bad offensive decision. We compared the effectiveness of the training protocols by using conventional tactics board and the proposed VR system. Furthermore, we investigated the influence of using prerecorded 360-degree panorama video and computer simulated virtual content to create immersive training environment.
