摘要
设计基于USBD12和加速度计的空中键鼠,通过手势在空中的动作便可控制鼠标的移动。设计的研发调试过程中,采用了加速度传感器数据采集、USB设备gadget层HID设备、LCD-NOKIA5110显示、AVR单片机熔丝位的配置、蓝牙模块、手势动作识别算法、菜单与UI界面等模块的软、硬件调试,接收端有一个USB口,插入PC后被识别为一个标准HID人体学输入设备,无须驱动,即插即用。用户的操作达到可动态交互的目的。采用动作手势识别算法,蓝牙模块等实现了通过手势在空中的动作便可控制鼠标的移动,通过按键进行对键盘的操作,并且不需要连接线,通过蓝牙与插在电脑上的接收端相连接通信,达到动态交互的目的。
An air mouse and keyboard combo pack based on USBD12 and accelerometer was designed, which can control the mouse movement by means of the gestures in the air. In the process of development and debugging of the design, the mod- ules of accelerometer sensor data acquisition, gadget-layer HID device of USB device, LCD-NOKIAS110 display, configuration of AVR MCU fuse bit, Bluetooth, hand gestures recognition algorithm, menu and UI interface are used for software and hard- ware debugging. A USB port at the receiving end is recognized as a standard HID after PC insertion, which is free-drive, and plug and play. The operation of users can realize dynamic interaction. The gesture recognition algorithm and Bluetooth module are used to control the movement of mouse and keyboard combo pack by means of the gestures in the air. The keyboard is operat- ed via keys and needn＇t connecting lines, which is connected with the terminal end inserted into computer through Bluetooth for communication to realize dynamic interaction.
