A virtual‐sound catch ball game system was developed to improve the quality of life of the visually impaired. Computer‐generated virtual sound balls were represented by stereo sounds, comprising localization parameters such as the interaural time and level differences, echo, and head‐related transfer function. Ball‐catching success was determined by images of the hand captured by a USB camera. Two sessions of experiments with blind subjects demonstrated the importance of distance recognition for human localization capability. Moreover, the addition of an echo parameter enhanced the sound‐source image position and sense of enjoyment. The results showed that a virtual sound game is a good active‐entertainment option for the visually impaired.

听觉接球系统的发展，以改善盲人的生活质量

开发了虚拟声音接球游戏系统，以改善视障者的生活质量。计算机生成的虚拟声球由立体声表示，包括定位参数，例如耳间时间和水平差异，回声和与头部相关的传递函数。接球成功取决于USB摄像头捕获的手的图像。为期两天的盲人实验证明了距离识别对人类定位能力的重要性。此外，增加回声参数可以增强声源图像的位置和愉悦感。结果表明，对于有视觉障碍的人来说，虚拟声音游戏是一种很好的主动娱乐选择。
