    • An apparatus and method for assessing a hazard associated with an object are disclosed. The apparatus includes a haptic input/output device coupled to a computer with haptic modeling software and a display device. A virtual object and a virtual passageway are displayed on the display device. The virtual passageway includes a haptic layer along a surface thereof. Force applied by a user to the haptic input/output device causes a cursor on the display device to move the virtual object into the virtual passageway. An interaction of the virtual object with the haptic layer generates a virtual contact force which may be determined by the user sensing a corresponding tactile feedback force generated by the haptic input/output device and/or by the computer processor. The magnitude of the virtual contact force may be used to assess a hazard associated with the virtual object.
    • 公开了一种用于评估与物体相关的危险的装置和方法。 该装置包括利用触觉建模软件和显示装置耦合到计算机的触觉输入/输出装置。 在显示装置上显示虚拟对象和虚拟通道。 虚拟通道包括沿其表面的触觉层。 由用户施加到触觉输入/输出设备的力使得显示设备上的光标将虚拟对象移动到虚拟通道中。 虚拟对象与触觉层的交互产生虚拟接触力,虚拟接触力可以由用户感测由触觉输入/输出设备和/或计算机处理器产生的对应的触觉反馈力来确定。 虚拟接触力的大小可用于评估与虚拟物体相关的危险。
