在本文中，我们提出了一种新颖的声学传感技术，可以识别两种方便的输入动作：手势和身体触摸。我们通过观察手腕周围在体内传播的波的频谱来实现这些目标。我们的方法可以同时实时识别手势和身体触摸，并有望通过组合它们来获得丰富的输入变化。我们进行的一项用户研究显示，手势、前臂触摸和手背触摸的分类准确度分别为 97%、96% 和 97%。
In this paper, we present a novel acoustic sensing technique that recognizes two convenient input actions: hand gestures and on-body touch. We achieved them by observing the frequency spectrum of the wave propagated in the body, around the periphery of the wrist. Our approach can recognize hand gestures and on-body touch concurrently in real-time and is expected to obtain rich input variations by combining them. We conducted a user study that showed classification accuracy of 97%, 96%, and 97% for hand gestures, touches on the forearm, and touches on the back of the hand.
