Tongue control with low profile, passive mouth tags is demonstrated as a human-device interface by communicating values of tongue-tag separation over a wireless link. Confusion matrices are provided to demonstrate user accuracy in targeting by tongue position. Accuracy is found to increase dramatically after short training sequences with errors falling close to 1% in magnitude with zero missed targets. The rate at which users are able to learn accurate targeting with high accuracy indicates that this is an intuitive device to operate. The significance of the work is that innovative very unobtrusive, wireless tags can be used to provide intuitive human-computer interfaces based on low cost and disposable mouth mounted technology. With the development of an appropriate reading system, control of assistive devices such as computer mice or wheelchairs could be possible for tetraplegics and others who retain fine motor control capability of their tongues. The tags contain no battery and are intended to fit directly on the hard palate, detecting tongue position in the mouth with no need for tongue piercings.
通过无线链路传输舌标分离值，展示了使用低调、无源口腔标签的舌头控制作为人机接口。提供混淆矩阵以证明用户通过舌头位置进行定位的准确性。发现经过短训练序列后，准确性显著提高，误差幅度接近1%，且无目标遗漏。用户能够快速高精度地学习准确瞄准，这表明该设备操作直观。这项工作的意义在于，创新的、非常不显眼的无线标签可用于基于低成本和一次性口腔安装技术提供直观的人机接口。随着适当读取系统的开发，四肢瘫痪者和其他保留舌头精细运动控制能力的人有可能控制诸如电脑鼠标或轮椅等辅助设备。这些标签不含电池，旨在直接安装在上颚，无需刺穿舌头即可检测口腔中的舌头位置。
