基于MEMS加速度的三维无线鼠标设计与实现

The Design and Implementation of MEMS Accelerometer-based 3D wireless mouse

当前市面上可见鼠标大部分采用光电技术,然而这些技术不能离开辅助桌面来确定位置。不同于前面的研究,本文利用三轴加速度倾斜角测量特性,而不是位移和加速度关系,来实现三维空间无线鼠标,能够减小噪声影响,并消除了传统鼠标辅助台面的束缚,可以在三维空间中自由运动。

In the market,most mouses for computer are photoelectric.However they can not move freely without the desktop.Different from the previous research,we design a new 3D mouse,using the attitude measurement property of 3 axis accelerometer in steady of the displacement from the acceleration,which might decrease the noise effect,and overcome the constraint of the desktop,might move freely in the 3D space.
