This paper presents a project on the development of a cursor control emulating the typical operations of a computer-mouse, using gyroscope and eye-blinking electromyographic signals which are obtained through a commercial 16-electrode wireless headset, recently released by Emotiv. The cursor position is controlled using information from a gyroscope included in the headset. The clicks are generated through the user's blinking with an adequate detection procedure based on the spectral-like technique called Empirical Mode Decomposition (EMD). EMD is proposed as a simple and quick computational tool, yet effective, aimed to artifact reduction from head movements as well as a method to detect blinking signals for mouse control. Kalman filter is used as state estimator for mouse position control and jitter removal. The detection rate obtained in average was 94.9%. Experimental setup and some obtained results are presented.
本文介绍了一个使用眼球运动肌电信号和陀螺仪来模拟鼠标操作的项目。眼球运动肌电信号是通过 Emotiv 公司最近发布的一款 16 电极无线耳机获取的。该项目使用耳机中的陀螺仪来控制光标位置,通过眨眼来实现点击操作,眨眼信号的检测采用基于经验模态分解(EMD)的频谱类似技术。EMD 是一种简单快速的计算工具,用于减少头部运动产生的伪迹,以及检测用于鼠标控制的眨眼信号。卡尔曼滤波器被用作鼠标位置控制和去除抖动的状态估计器。平均检测率达到了 94.9%。本文还介绍了实验设置和部分实验结果。
