基于虚拟现实技术的姿态控制应用研究

Research on Attitude Control based on Virtual Reality Technology

人能够在任何状态下都能保持身体姿势平衡是最基本的要求,空间的方位感和身体的平衡感来自于视觉系统、本体感系统、及前庭系统,这些感知系统获得的信息集中到中枢神经系统,再由中枢神经系统综合各方面的信息从而确定方位和身体姿势平衡。对于中枢神经系统如何综合个方面信息并使人的身体保持平衡,一直是生物医学研究一个重要方面。本文运用虚拟现实技术,建立一个使用且合理的身体姿势平衡评估系统,针对研究者所提出的不同模型和策略,解释各个感知系统所获信息的权重比例。

Keeping postural balance is the basic requirement for a person in any state. The senses of space and balance are got from vision system, ontology System and vestibular system. The information of these senses is collected in central nervous system, then various aspects of information analyzed by central nervous system determine the azimuth and attitudes. That how to synthesize the information in order to keep balance of human body is a significant study in biomedicine. The paper adopted virtual reality technology to set up a feasible balance assessment system. Meanwhile, and elucidated the weight ratios of the information got from each sense system by using different models and strategies.
