本研究旨在为聋哑人的手语释义“配音”，以帮助聋哑人和普通人进行交流，设计基于MSP430F5529单片机控制传感芯片FDC2214的简单手语识别系统。该系统采用电容式传感芯片来采集并处理手势变化的信号，再将这些信号通过串口线传送给单片机处理。它可以分两种模式输出，一方面将手势的变化情况通过显示屏以文字的形式输出，以便不懂手语的人理解聋哑人的语言；另一方面它可以通过单片机对频率的变化进行处理，找出手势与语音芯片中事先存储语言片段的对应关系，通过指令控制对变化的手势做出相应的语音播报。所设计的系统能够识别十种手势和日常用语的正确输出。
This study aims to convert the gestures of deaf and dumb into “dubbing” and to help the deaf-mute people communicate with ordinary people. It would complete the simple sign language recognition system based on MSP430F5529 microcontroller control sensor chip—FDC2214. The system uses a capacitive sensing chip to collect and process signals with gesture gestures changes, and then transmits these signals to the microcontroller through a SPI. It can be output into two modes. On the one hand, the change of the gesture is output in the form of text through the display screen, so that the person who does not understand the sign language understands the language of the deaf person; on the other hand, it can process the change of the frequency by the single chip mi-crocomputer. It is found the corresponding relationship between the gesture and the pre-stored language segment in the voice chip, and the corresponding voice announcement of the changed gesture is controlled by the instruction. The system is designed to recognize the correct output of ten gestures and daily languages.
