如今越来越多的无线体感输入设备应用在多媒体场合。针对该设备功能单一同时价格昂贵等缺点,本文提出了一种简易多功能体感输入系统。该系统具有鼠标、手柄、滚轮等多种计算机外设功能。设计采用加速度传感器感应手掌在空间x和y方向上的加速度大小,将加速度信号处理转换成手掌的倾角姿态、转动角速度等运动参数,同时根据用户选择的功能模式动态调用相应的控制算法对手势运动进行分析处理,实现不同的输入设备功能。实验结果表明该输入系统能顺利的反映用户操作意图,操作简便、工作稳定,特别适合会议、教室、展厅等场合。
Today, more and more wireless somatosensory input devices are used in multimedia applications. In view of the single function of the device is expensive and so on, this paper presents a simple multi-functional somatosensory input system. The system has a mouse, handle, wheel and other computer peripherals. The accelerometer sensor is used to sense the acceleration of the palm in the x and y directions. The accelerometer signal is converted into the palm angle and rotation angle. At the same time, the corresponding control algorithm is dynamically called according to the user’s selected function mode. Analysis and processing, to achieve different input device functions. The experimental results show that the input system can reflect the user’s operation intention smoothly, and is easy to operate and work steadily. It is especially suitable for conferences, classrooms, exhibition halls and other occasions.
