基于颞肌表面肌电的鼠标装置研究

Study of the mouse device based on surface EMG signals of the temporalis

目的设计一种基于颞肌表面肌电的鼠标装置,用于解决高位截瘫、上肢残疾等手部功能障碍者操作鼠标的难题。方法提出一种基于表面肌电信号控制鼠标的方法,通过分析与试验,选取面部颞肌肌电信号作为控制信息,以咬牙作为触发动作,根据不同咬牙动作时,面部颞肌产生不同的肌电信号特征,设计一种利用颞肌表面肌电信号进行鼠标控制的装置。结果实验结果表明,利用该装置,受试者能够通过简单的咬牙动作实现控制鼠标的目的。结论利用颞肌表面肌电控制鼠标的方法是切实可行的,基于该方法设计的鼠标装置具有较好的应用推广价值。

Objective To design a mouse device based on surface EMG signals of the temporalis for people who suffered with paraplegia,upper limb disability or impaired hand function to be able to operate the mouse.Methods A control method for mouse operation based on surface EMG was presented.Through analysis and test,facial surface EMG signals of the temporalis were selected as the control signal and with the bite as a trigger action.EMG signals with different characteristics could be generated from the temporalis muscle according to different bite actions,and thus a mouse device controlled by the facial surface EMG signals from the temporalis was designed.Results The test proved that by using the device,subjects could control the mouse by a simple bite action.Conclusions The control method for mouse operation based on surface EMG is feasible,and the mouse device designed according to this method is valuable in practical application.
