A Wireless Magnetoresistive Sensing System for an Intra-Oral Tongue-Computer Interface

📋 论文概要

该论文提出了一种用于口内舌-计算机接口的无线磁阻传感系统，通过追踪附着在舌头上的磁性示踪剂的位置，将舌头手势转换为用户定义的命令，从而帮助严重肢体残疾人士控制环境。该系统具有非侵入性、可穿戴和无线等特点，解决了现有辅助技术中侵入性强、使用不便的问题。

💡 主要创新点

• 提出了一种基于磁阻传感器的无线舌部运动追踪系统，实现了非侵入式、可穿戴的舌-计算机接口。
• 开发了传感器信号处理算法，能够将舌头手势实时转换为用户定义的命令。
• 系统设计支持通过粘合剂或穿刺方式将磁性示踪剂附着在舌头上，提高了使用的灵活性和舒适性。

invasive, unobtrusive, wireless, and wearable tongue-operated assistive technology (AT) that enables individuals with severe physical disabilities to control environments with their free tongue motion. An array of magnetic sensors wirelessly tracks the position of a magnetic tracer attached to the tongue via adhesives or piercing, and a sensor signal-processing (SSP) algorithm converts a set of tongue gestures to userdefined commands in real time [1]. In the external TDS (eTDS), which is undergoing clinical trials, electronics are embedded in a customized headset, which supports the sensors on a pair of bilateral extensions near the cheeks [2]. Considering the importance of such ATs in users’ daily lives, the mechanical stability of the eTDS on the head is a concern. In this paper we report an intraoral
