五自由度三维鼠标的设计与实现

Design and implementation of a 5-degree-of-freedom 3-D mouse

为开发中国自主知识产权的三维人机交互设备,满足虚拟现实、网络游戏和手术模拟等的需求,设计并实现了五自由度三维USB(通用串行总线)鼠标。实现了硬件电路、固化程序、驱动程序和应用程序的设计等。该鼠标在传统二维鼠标的基础上增加2个自由度,这2个自由度以滚轮的形式分布在鼠标的两侧,分别实现绕X轴和Y轴的旋转。该鼠标完全兼容传统的二维鼠标,接入计算机就能直接当传统的二维鼠标使用,安装新的驱动程序后能实现三维交互输入,并且不再另外需要二维鼠标的配合,单手操作即可。实验和样机表明:该五自由度三维鼠标交互输入的效果良好,并且操作简单方便。

A 5-degree-of-freedom 3-D USB mechanical mouse was designed for 3-D interactive devices for virtual reality application, 3-D games, and surgical simulations. The design includes the hardware, software, and driver design as well as applications. The mouse has two more degrees of freedom than traditional 2-D mice. The two extra wheel controllers are placed on the two sides of the mouse to give rotations around the X and Y axes. This mouse is fully compatible with the standard 2-D mouse and can be used as a 2-D mouse without additional drivers. With own driver, it is a 3-D interactive input device which does not need an additional 2-D mouse, so it can be operated with just one hand. Tests show that the 5-degree-of-freedom 3-D mouse has good interactive input functions and is convenient to operate.
