我们开发了一种新的虚拟现实（VR）系统，可以在3D图像和手指之间直接交互，而无需佩戴特殊的3D眼镜，也无需在手指上附加任何标记或检测器。此外，它使用户免于视觉疲劳。该系统由128方向3D显示器、PC集群和指尖检测系统组成。128方向显示器提供自然的3D图像，其不具有视差-聚散度冲突并且具有非常平滑的运动视差。它不同于传统的多视图显示器，因为它精确地重建来自3D对象的光线。它包含128个LCD面板，其上显示的128幅图像以0.23°的水平角间距在不同的水平方向上投影。PC集群由16台PC组成。每台PC产生8个视频信号。指尖检测系统采用立体红外（IR）相机。通过三角测量来估计指尖的3D位置。我们还做了三个应用程序。第一个使指尖操作的3D图像在VRML格式。第二个是3D绘图程序，允许用户在空中画线。最后一个使得能够通过手指旋转360°方向图像的3D图像。
We developed a new virtual reality (VR) system that enables direct interaction between a 3D image and a finger without wearing special 3D glasses and without attaching any marker or detector to the finger. Moreover, it frees the user from visual fatigue. The system consists of a 128-directional 3D display, a PC cluster, and a fingertip detection system. The 128-directional display provides a natural 3D image which does not have the accommodation-vergence conflict and has very smooth motion parallax. It differs from conventional multi-view displays in that it precisely reconstructs rays from a 3D object. It contains 128 LCD panels, and the 128 images displayed on them are projected in different horizontal directions with a horizontal angle pitch of 0.23°. The PC cluster consists of 16 PCs. Each PC generates eight video signals. The fingertip detection system employs a stereo infrared (IR) camera. The 3D position of the fingertip is estimated by triangulation. We also made three application programs. The first one enables the fingertip manipulation of a 3D image in VRML format. The second one is a 3D drawing program that allows users to draw lines in the air. The last one enables the rotation of a 3D image of a 360° directional image by the finger.
