基于MEMS加速度计的虚拟现实技术的研究*

本文提出并实现了一种基于MEMS(Micro-Electro-Mechanical Systems)加速度计等传感器的隔空书画和情感宣泄手套。在书画模式下,指套笔在空间的随意书写和绘画,将其书写绘画轨迹信息重现于虚拟画板上;宣泄模式下,构建了虚拟情感宣泄场景,并采用关键姿态帧离散化运动序列,通过关键姿态和人体运动特征向量映射重构实现运动识别,最后对最终的识别结果进行动态修正以拟合用户输入。样机验证实验表明,本系统实现了隔空随意书画和“发泄吧”的虚拟化,是虚拟现实技术的一项重要尝试。

Research of Virtual Reality Technology Based on MEMS Accelerometer

In this paper, the author proposed and implemented an empty isolation of paintings and emotional catharsis glove based on MEMS accelerometer sensor etc. In painting mode, by fingerstall pen writing and painting randomly in the space, the trace information will be reproduced on a virtual drawing board. In the catharsis scene, built a virtual scene using a discrete movement sequence of critical altitude frame, by critical altitude reconstruction and human motion characteristic vector map to achieve movement recognition, finally, modified the final recognition results for dynamical to fit the user entry. Prototype validation experiments suggest that it can achieve an random empty isolation of paintings and virtualization of "catharsis bar", which is an important try of virtual reality.
