感知口腔内的运动和手势一直是可穿戴研究界面临的一个长期挑战。本文介绍了EchoNose,一种新型的鼻子接口,它探索了一种独特的传感方法,通过分析鼻腔和口腔内的声学信号反射来识别与嘴巴,呼吸和舌头相关的手势。该接口结合了一个扬声器和一个麦克风放置在鼻孔,发出听不见的声音信号,并捕捉相应的反射。这些接收到的信号使用定制的数据处理和机器学习管道进行处理,从而能够区分涉及语音、舌头和呼吸的16种手势。一项针对10名参与者的用户研究表明,EchoNose在识别这16种手势时的平均准确率为93.7%。基于这些有希望的结果,我们讨论了潜在的机遇和挑战,在未来的各种应用中应用这种创新的鼻子接口。
Sensing movements and gestures inside the oral cavity has been a long-standing challenge for the wearable research community. This paper introduces EchoNose, a novel nose interface that explores a unique sensing approach to recognize gestures related to mouth, breathing, and tongue by analyzing the acoustic signal reflections inside the nasal and oral cavities. The interface incorporates a speaker and a microphone placed at the nostrils, emitting inaudible acoustic signals and capturing the corresponding reflections. These received signals were processed using a customized data processing and machine learning pipeline, enabling the distinction of 16 gestures involving speech, tongue, and breathing. A user study with 10 participants demonstrates that EchoNose achieves an average accuracy of 93.7% in recognizing these 16 gestures. Based on these promising results, we discuss the potential opportunities and challenges associated with applying this innovative nose interface in various future applications.
