Train in Virtual Court

Abstract

In this paper, we present a basketball tactic training system based on multimedia and virtual reality (VR) technologies to improve the effectiveness and experience of tactic learning. A tablet-based digital tactic board (2D BTB) is developed to draw, select, or search for a target offensive tactic. The 2D player trajectories of the target tactic are then converted into 3D player animation immediately to provide virtual reality content for experiencing and practicing the target basketball tactic. Through the VR environment, the learner can vividly experience how a tactic is executed in a global view or from a specific player's viewing direction. The basketball tactic movement guidance and virtual defenders are rendered in our VR system according to the target offensive tactic and the learner's head pose. We also design an experimental process to validate that the proposed VR training system not only makes the learner feel more like playing in a real basketball game but also improves the efficiency and effectiveness of learning new basketball tactics.
