【摘要】 研制了一种操作者可以通过不同的手势来进行虚拟现实系统人机交互的跟踪设备,通过采用光纤传感器来测量手指的弯曲角度及交流式电磁跟踪系统来测量手掌的空间位置,推导了根据加速度计和磁阻传感器的输出计算手掌空间位置和姿态的方法并研究了光纤传感器的输出与手指弯曲角度的关系,试验结果证明了系统的有效性。
【Abstract】 An interaction device that enables an operator to interact with different gestures in a VR (Virtual Reality) system is presented. The joint angles of the individual fingers are measured with fiber optic sensors and the relative position and orientation of the palm are tracked with alternating current pulsed magnetic tracker. The algorithm to calculate the spherical coordinates from the output of the accelerometers and magnetoresistive sensors is deducted. The relationship between the output of the fiber optic sensor and the actual flexure angle is studied. Experiment result shows the effectiveness of the proposed device.
