Towards a realization of an acoustic visual aid system for the visually impaered, a basic studies were made using 3D acoustic sound processor. The system displays acoustically through the headphone 3D sounds which corresponds the localization of an obstacles to be catched. To evaluate such acoustic system, a bsic study was made also in a virtual space, where an obstacle is thought to exist. In this basic study, the subjects moves virtually using ajoystic bar, which moves camera position viratually again.In actual space, the subjects wears a headmount camera, which catches the obstacles at last before generating sounds corresponding the position of the obstacles. The over all results show that this method is effective to reach and to catch an obstacles , even the time is necessary than expectation, which shall be reduced using high speed computers.

为了实现视力障碍的声学视觉援助系统，使用3D声音处理器进行了基础研究。该系统通过耳机3D声音表现出声学，这对应于要捕获的障碍的定位。为了评估这种声学系统，在虚拟空间中也进行了BSIC研究，该空间被认为存在。在这项基础研究中，受试者实际上是使用Ajoystic棒移动的，该杆再次流动地移动相机位置。在实际的空间中，受试者戴着倒数摄像头，该摄像头终于抓住了障碍物，然后产生声音与障碍物的位置相对应。所有结果表明，这种方法可以有效地达到和捕捉障碍，即使时间比期望，也应使用高速计算机减少。
