Direct Manipulation of 3-Dimensional Shape Models in Virtual Work Space

在计算机上实现对三维形状模型的直接操作是人机界面研究的重要内容之一。我们可以无意识地利用视觉、触觉和力觉等感觉，做出各种三维形状，例如积木、粘土等。为了实现自然的人机界面，有必要构建虚拟的工作空间，在那里我们可以像在真实的空间中一样在计算机上操纵三维形状模型。通过构建这样的空间，我们可以用自己的手和手指直接在我们面前的虚拟空间中操纵三维形状模型。此外，我们希望我们可以实现人机界面的三维形状模型的操作。本文构建了一个虚拟工作空间，实现了对三维形状模型的直接操作.从感知信息流的角度分析了真实的空间中的形状建模。结果表明，视觉、触觉和力觉知觉循环的存在.我们制作了一个虚拟实现感知循环的装置.构造了旋转体造型的虚拟工作空间。

It is one of the most important researches on human interface to realize direct manipulation of three dimensional shape models on computers. We can make various three dimensional shapes, for example, building blocks, clay, etc. by using sensations such as visual, tactile and force sensation etc. unconsciosuly. To realize natural human interface, it is necessary to construct virtual work space where we can manipulate three dimensional shape models on computers just like in real space. By constructing such space, we can manipulate three dimensional shape models directly in virtual space in front of us with our own hands and fingers. Moreover, it is expected that we can realize human interface for manipulation of three dimensional shape models. We constructed a virtual work space for direct manipulation of three dimensional shape models.Research results are as follows.1. We analyzed shape modeling in real space by noticing flow of perceptual information. As a result, we showed the existence of perception cycle of visual, tactile and force sensation.2. We made a device which realizes the perception cycle virtually.3. We constructed virtual work space for rotating shape modeling.
