项目摘要

We attempted to demonstrate the relationship between body sway and virtual tapping sounds motion. We developed a virtual tapping sounds presentation system which listeners perceive objects by echolocation. Experimental conditions were : (1)tapping motions in back and forth direction, (2)virtual tapping sounds motion and environmental noise (pink noise) in back and forth direction, (3)no sound, (4)virtual tapping sounds motion in lateral direction, and (5)virtual tapping sounds motion and environmental noise in lateral direction.Results were : (1)no sound condition indicated no body sways, (2)body sway responded to virtual sounds motion both in back and forth direction and lateral direction even if there individual difference, (3)virtual tapping sounds motion and environmental noise condition made blind participants larger sways rather than virtual tapping sounds motion.We also attempted to develop acoustic system which presented a virtual interspace using only pink noise. We asked a blind person to evaluate to perceive an interspace in front of him. However, it was hard to recognize it. We have to consider this system.

我们试图证明身体摇摆和虚拟敲击声音运动之间的关系。我们开发了一个虚拟敲击声呈现系统，听众通过回声定位感知物体。实验条件为：（1）在前后方向上的敲击运动，（2）虚拟敲击声音运动和环境噪声（3）没有声音，（4）虚拟敲击声在横向方向上的运动，以及（5）虚拟敲击声在横向方向上的运动和环境噪声。（1）无声音条件表明没有身体摇摆，（2）身体摇摆对前后方向和横向的虚拟声音运动都有响应，即使存在个体差异，（3）虚拟敲击声运动和环境噪声条件使盲人受试者的摇摆幅度比虚拟敲击声运动更大，我们还尝试开发了仅使用粉红噪声呈现虚拟空间的声学系统。我们让一个盲人去评估他面前的空间。但是，很难识别它。我们必须考虑这个系统。
