成功操纵物体的一个组成部分是触摸或力的感觉。远程机器人（远距离控制的机器人）实验表明，力和接触的感觉可以提高此类任务的效率和准确性。许多人认为虚拟环境中的任务也是如此。不幸的是，不可能以与真实对象相同的方式实际掌握虚拟对象，因为虚拟对象是在计算机中定义的，而用户存在于现实世界中。因此，必须有某种中间设备为用户提供触摸效果，无论是通过虚拟环境本身还是在对象的物理模型中，然后将信息传递到虚拟环境并向用户显示虚拟对象。在东京大学，我们正在试验表面显示，这种方法允许用户通过触摸计算机外部中间设备呈现的对象表面的物理模型来直接操纵虚拟环境中的对象。我们已经创建了这种设备的原型，用于测量施加在表面上的力。我们还实现了控制和计算方法，并在用户实验中评估了设备和方法。这些实验验证了我们工作背后的概念，我们正在继续研究实施问题。 >
An integral part of successfully manipulating objects is the sensation of touch or force. Experiments with telerobots (robots controlled at a distance) show that the sensation of force and contact improves the efficiency and accuracy of such tasks. Many believe that the same can be said of tasks in a virtual environment. Unfortunately, it is not possible to actually grasp a virtual object in the same manner as you would a real object because virtual objects are defined in the computer, while the user exists in the real world. Thus, there must be some intermediate device that provides the user with the effects of touch, either through the virtual environment itself or in a physical model of the object, which then communicates information to the virtual environment and displays the virtual object to the user. At the University of Tokyo, we are experimenting with surface display, a method that allows users to directly manipulate an object in a virtual environment by touching a physical model of the object's surface as presented by an intermediate device outside the computer. We have created a prototype of such a device that measures the force exerted on the surface. We have also implemented control and calculation methods, and have evaluated both the device and the methods in experiments with users. These experiments have validated the concepts underlying our work, and we are continuing to investigate implementation issues. >
