摘要： 在基于ARToolKit的增强现实系统中，注册在不同标识物上的三维虚拟物体因交互行为而发生碰撞时，虚实融合会失真。为解决该问题，提出一种能增加虚拟交互功能的碰撞反应算法。根据检测到的碰撞信息，实时调整虚拟物体碰撞后相对于标识物的位置和姿态，消除物体穿透现象，保持虚实融合场景的真实感。实验结果表明，该虚拟交互方法能获得比较自然和真实的交互性体验。

Abstract: In the augmented reality system based on ARToolKit, the virtual objects are registered on the different marks collide because of interaction which causes unreal mix situation. To solve this problem, this paper proposes an algorithm which can adjust the location and pose of virtual objects according to detected information about collisions, and make mix situation of virtual and actual reality remain realistic. User can obtain more interactive experience from the system. Experimental result shows that this method can get a nature and true interactive experience.
