Abstract

Studies show that globally, about 1 in 50 people are living with paralysis and the amount increasing year by year. Paralysis can leave present these people with no interest in life leading to mental depression. An assistive device can aid a disabled person with a support to lead an easy life and it should be able to efficiently discern user's intention providing ease of usage. This paper proposes a wireless, wearable tongue controlled assistive device called Optical Sensor Based Tongue Controlled Assistive Device (OTCAD). Here the tongue movement is sensed using a small and low cost infrared (IR) sensor, mounted bilaterally near user's cheek. The user uses his/her tongue to change the reflection intensity of the sensor and this signal change is converted into user commands through signal processing. These commands are then wirelessly transmitted to PC/Smartphone through which the user can control their home environment, move a wheel chair or pass information to their care taker.
使用光学传感器的可穿戴无线舌控辅助设备
研究表明,在全球范围内,大约每50人中就有1人患有瘫痪,而且这一数字正在逐年增加。瘫痪会让这些人对生活失去兴趣,导致精神抑郁。辅助装置可以帮助残疾人轻松生活,并能有效识别使用者的意图,方便使用。本文提出了一种无线、可穿戴的舌控辅助装置——基于光学传感器的舌控辅助装置(OTCAD)。在这里,舌头的运动是用一个小而低成本的红外(IR)传感器来感知的,安装在用户脸颊附近的两侧。用户用舌头改变传感器的反射强度,这种信号变化通过信号处理转化为用户命令。然后,这些指令被无线传输到PC/智能手机上,用户可以通过它控制他们的家庭环境,移动轮椅或向他们的护理人员传递信息。
