    • The present invention is directed toward providing interactive haptic collision detection between a stationary and a moving object in a virtual reality environment. A user grasps the arm of a haptic device and manipulates an object as viewed on a virtual reality display. As any portion of the manipulated object comes too close to the surface of the stationary object, the haptic device imposes feedback forces against the user's efforts that increase in magnitude as the user manipulates the object beyond a force boundary proximate to the surface of the stationary object. The feedback forces are applied directionally in line with the shortest path between the surfaces at risk of collision. Several measures can be implemented by the user to reduce the computation load involved in constantly comparing the distances between points on the surface of the movable object and points on the surface of the stationary object without seriously compromising the collision detection and avoidance functions of the system. Furthermore, while the invention provides for up to six degrees of freedom for manipulating objects and providing haptic feedback, the system also accommodates three degrees of haptic freedom and feedback, with the additional three degrees of rotational feedback being provided visibly or audibly.
    • 本发明旨在在虚拟现实环境中提供固定和移动物体之间的交互式触觉碰撞检测。 用户抓住触觉装置的手臂并且在虚拟现实显示器上观察时操纵对象。 随着被操纵物体的任何部分太靠近静止物体的表面,触觉装置对用户的努力施加反作用力,当使用者操纵物体超过固定物体表面的力界面 。 反馈力按照碰撞风险的表面之间的最短路径进行定向应用。 用户可以采取多种措施来减少持续比较可移动物体表面上的点与固定物体表面上的点之间的距离所涉及的计算负荷,而不会严重影响系统的碰撞检测和回避功能。 此外,尽管本发明提供用于操纵物体和提供触觉反馈的多达六个自由度,但是该系统还容纳三度的触觉自由度和反馈,另外三度旋转反馈被可视地或可听见地提供。
