Implementation of Ultrasonic Gesture Interface

在这项研究中，我们开发了运动接口技术，使机器控制能够通过机载超声成像检测操作员的运动。为此，我们利用MEMS超声传声器和现场可编程门阵列信号处理器构建了一种低成本的阵列探测器。针对未来的应用发展，我们提出了一种新的运动捕捉算法，并验证了算法的有效性。

In this research we developed the motion-interface technology which enables machine controls detecting the operator's motions via air-borne ultrasound imaging. For this purpose we constructed a low cost array detector using MEMS ultrasound microphones and an FPGA signal processor. For the future application developments we proposed a new motion capture algorithm and confirmed the effectiveness.
