Study of three-dimensional mouse

这个项目的目的是实现三维鼠标作为计算机的输入设备。该鼠标包含加速度传感器、角速度传感器和磁传感器，用于检测三维量。加速度和角速度传感器通过整合它们的信号来检测鼠标的相对运动，磁传感器检测鼠标的绝对位置。在研究中，设计和制作了用于鼠标的微机械加速度和角速度传感器，并利用神经网络方案计算了F鼠标的位置。采用多芯片服务，设计和制作了传感器接口专用集成电路。因此，获得了足够小的三维鼠标设备，它们可以在1立方米左右的空间内检测鼠标位置，并且具有足够的精度，可以用于鼠标应用。

The aim of this project is to realize three-dimensional mouse as an input device of computers. The mouse contain acceleration sensor, angular velocity sensor and magnetic sensor which detect three- dimensional quantities. The acceleration and angular velocity sensors detects the relative movement of the mouse, by integrating their signal, and magnetic sensor detects the absolute position of the mouse.In the research, micromachined acceleration and angular velocity sensors are designed and fabricated for the mouse, and position of the F mouse are calculated using neural network scheme. Moreover the interface ASIC for sensors are designed and fabricated using multi-chip service. As a result, sufficiently small devices for three-dimensional mouse were obtained and they can detect the mouse position around 1 cubic meter space with sufficient accuracy for the mouse application.
