A Handling System of Virtual Object with the Sense of Touch

该虚拟物体处理系统可用于工业设计、艺术领域等交互式3D建模的应用。为了实现对虚拟物体的高精度、真实感的直接操作，研制了一种特殊类型的触控笔。手写笔的手柄安装在驱动机构上，但尖端是一个虚拟物体，好像与手柄结合在一起。针对真实感运动视差的显示，研制了一种基于PSD和专用图形处理器的快速眼位测量系统。这种虚拟的尖端不仅可以直接处理，还可以使用图形硬件进行实时触摸决策。因此，它能够通过控制握持支撑机构来传输来自虚拟对象的触觉。

This virtual object handling system can be used for applications of interactive 3D modeling such as industrial design and field of art. For realizing direct handling of virtual object with high accuracy and really existing sensation, a special type of stylus was developed. The grip of stylus is mounted on the driving mechanism, however, the pointed end is a virtual object displayed as if united with the grip. A fast eyes positions measuring system using PSD and special graphics processor were developed for display of realistic motion parallax. This virtual pointed end enables not only direct handling, but also real time touch decision using graphics hardware. So it enables transmission of the sense of touch from virtual object by controlling the grip supporting mechanism.
