人工現実感技術による人間の空間認識特性の解明に関する研究

文摘：利用本实验室研制的由头盔显示器、图形工作站、Polhemus传感器和DataGlove组成的系统进行了各种初步的虚拟现实实验。首先，我们通过实验发现，在虚拟现实环境中，人的工作效率对时间延迟的容忍度是有限的。其次，我们开发了一种更简单或更近似地模拟虚拟世界环境中的物理现象的方法，以适应目前计算机计算能力的有限。最后，我们开发了一种新型的头盔显示系统--透视式头盔显示器(STHMD)。其中我们将3D虚拟环境叠加到实际环境中。我们讨论了实现这种类型的头盔显示器的技术问题，并讨论了补偿这些问题的方法。

Abstract : We conducted various preliminary experiments in virtual reality using a system developed in our lab composed of a head-mounted display, a graphics workstation, a polhemus sensor and a DataGlove.First, we found through our experiments that there is a limit of tolerance to time delay in the work efficiency of human performance in virtual reality environments.Second, we developed a way to more simply or approximately simulate physical phenomena in our virtual world environment in order to accommodate for the limited computing power of present computers.Finally, we developed a new type of head-mounted display system which we call "See-Through Head-Mounted Display (STHMD)", in which we superimpose a 3D virtual environment onto an actual environment. We discuss technical problems in realizing this type of HMD and also discuss methods of compensating for these problems.
