摘　　要：针对目前虚拟训练软件常用的输入设备逼真度不足的问题,为虚拟训练软件设计了一种新的人性化接口设备(Human Interface Device,HID)-基于MEMS器件的虚拟训练动作获取系统。系统将微惯性测量原理应用于人体姿态检测,选用微机电系统(Micro Electro Mechanical Systems,MEMS)惯性器件构建微惯性测量单元(Micro Inertial Measurement Unit,MIMU)作为人体训练动作的硬件采集设备;采用VC++设计上位机系统软件,完成人体动作获取与识别算法,系统软件通过软件接口驱动虚拟训练软件。通过对原理样机测试,测试结果表明系统运行稳定可靠,解算精度在3°以内,满足虚拟训练的要求,且其操作体验较鼠标键盘操作更为逼真,沉浸感更强。该研究首次将微惯性测量单元应用于人体动作检测,拓展了MEMS器件的应用领域,极大增强了虚拟训练的真实感和训练效果,具有广阔的市场前景。This research was conducted to design a Human Interface Device （HID） for the virtual training software to improve the effect of virtual training. With the principle of Strap - down Inertial Navigation System, Micro Inertial Measurement Unit （MIMU） is designed with Micro Electro Mechanical Systems （MEMS） devices as the data acquisition unit to measure the human training motion. System algorithm is designed to acquire human training motion. The system software is programmed with VC ＋ ＋ ,which using software interface to communicate with the virtual training software. After testing the model machine, the results show that the resolving precision, which is 3° at least, satisfies the requirement of the virtual training software. This research expancls the application realm of MEMS devices, improves the effect of the virtual training, and then has a wide market future.
