The tongue's physiological complexity and hidden location inside the oral cavity, limit our ability to quantify its fast and dynamic motions. Our team has developed a discreet wireless intraoral wearable device to study the tongue motion. In this paper, tongue movements were analyzed during functional tasks of target reaching when controlling a cursor on a computer screen. Ten healthy individuals participated in this study. Movement trajectories were compared to straight lines using the maximum perpendicular distance error. Results suggest that the tongue directs the cursor closer to a straight line when moving along the anteroposterior and mediolateral direction. We also observed that with practice the movement error along the mediolateral axis decreases more than the error for the anteroposterior and angular movements.
舌头的生理复杂性及其在口腔内的隐藏位置限制了我们定量研究其快速和动态运动的能力。我们的团队开发了一种 discreet wireless intraoral wearable device，用于研究舌头运动。在本文中，我们分析了在控制计算机屏幕上的光标时进行目标到达的功能任务期间的舌头运动。十名健康个体参与了这项研究。使用最大垂直距离误差将运动轨迹与直线进行比较。结果表明，当沿前后和左右方向移动时，舌头将光标引导得更接近直线。我们还观察到，随着练习，沿左右轴的运动误差比前后轴和角运动的误差减小得更多。
