对基于虚拟现实训练系统的低成本3D声音系统评估

在基于PC的虚拟训练系统中,3D的声音仿真能够大幅度的提高VR系统的能力.然而,现实的3D仿真非常昂贵,而且计算混响,阻塞和延时效果需要配置具有强大运算能力的系统.因此,必须提供一个低成本的方案,使其能在更广的范围内得到应用.对一个低成本3D声音仿真系统的评测进行了重点阐述.实验设置基于常规的立体声耳机和一个可跟踪的头戴式设备,实验中使用不同信号在虚拟训练环境中来定位声音,最后从精度和速度来表述实验结果.

Evaluation of low-cost 3D sound system for immersive virtual reality training systems

Among a PC-based virtual training systems,a 3D sound simulation can improve the capabilities of VR systems dramatically.Unfortunately,realistic 3D sound simulations are expensive and demand a tremendous amount of computational power to calculate re-verberation,occlusion,and obstruction effects.So a cheaper alternative has to be provided,so that a broader range of is applied.The experimental system setup using conventional stereo headsets in combination with a tracked HMD device,and used signal types for loc...
