CAREER: Haptic Models of Large Structures Bozidar Stojadinovic ``I hear and I forget. I see and I remember. I do and I understand.'' Lao Tsu, 604-531 BCThe goal of this CAREER project is to make a tool for hapticstructural modeling. This tool will be a virtual environment. A userwill be able to see and fly through a large structure. The user will,also, be able to touch the structure, to feel its resistance, and topush on it. To do this, I intend to merge a haptic interface tool intoan augmented reality setting.My objectives for the next four years are:1. To make a virtual environment for modeling three-dimensionalframe structures using VRML and interface it to DRAIN-3DX, aprogram for structural analysis of civil structures.2. To incorporate a haptic interface in this virtual environmentand develop a haptic rendering methodology for large structure,enabling the user to push the structure and feel its deformation.3. To interface the virtual modeling environment and thereal laboratory environment by making it possible to addressvirtual and real sub-structures through the same interface. Development of a haptic structural modeling tool is a challenge.Haptic rendering of large objects is an open problem. Design of ahaptic interface to virtual and real substructures has not been donebefore, but may have a broader significance for a Network forEarthquake Engineering Simulation (NEES), a five-year NSF initiativetaking off in 1999.The challenges are here, but the benefits of having a haptic learningtool are huge! Students will be able to touch structures, resist landslides, feel earthquake vibrations and immerse in fluid flow. Thishaptic tool will take learning from hearing and seeing to touching anddoing... and understanding, as Lao Tsu meant two-and-a-half milleniaago.--

CAREER：大型结构的触觉模型 Bozidar Stojadinovic ``我听到，我忘记。 我看到了，我记得。 我知道，我理解。'' 老大津，公元前604-531年这个CAREER项目的目标是制作一个触觉结构建模的工具。这个工具将是一个虚拟环境。 用户将能够看到和飞行通过一个大的结构。 使用者也可以触摸到这个结构，感受到它的阻力，然后推它。为了做到这一点，我打算将触觉界面工具合并到增强现实环境中。我未来四年的目标是：1.利用VRML建立了三维框架结构的虚拟建模环境，并与土木结构分析程序DRAIN-3DX进行了接口.在虚拟环境中加入触觉接口，开发一种大型结构的触觉再现方法，使用户能够推动结构并感受其变形.通过同一个接口来处理虚拟和真实的子结构，从而将虚拟建模环境与真实的实验室环境连接起来。触觉结构建模工具的开发是一个挑战，大物体的触觉渲染是一个开放的问题。虚拟和真实的子结构的触觉接口的设计以前从未做过，但可能对地震工程模拟网络（NEES）具有更广泛的意义，这是一项于1999年启动的为期五年的NSF倡议。挑战就在这里，但拥有触觉学习工具的好处是巨大的！学生将能够触摸结构，抵抗山体滑坡，感受地震振动和沉浸在流体流动。这个形状的工具将把学习从听觉和视觉带到触觉和实践。和理解，就像老大津所说的两千五百年前。
