    很多人长时间操作电脑后揉着酸痛的手臂,于是想能否发明一种可以脱离桌面自由移动,又不改变使用习惯的无线鼠标。从而达到即能方便操作现有软件又能解除使用者的疲劳,扩大使用范围的目的。
    通过观察机械陀螺仪获得灵感,经过反复试验和四代作品改进,利用重力和惯性原理制作了内置万向节支撑的偏重心球壳体,固定在光电扫描鼠标之下。工作时手腕向需要方向转动,光电头与方向固定的球平面产生相对位移,将鼠标对桌平面扫描变为对球面扫描,输出位移信息,从而实现脱离桌面自由使用。
    本离桌式鼠标既可支撑使用亦可悬空使用大大减轻使用疲劳。除用于办公、教学,娱乐外,特别适合卧床,坐沙发等休闲及特殊场合使用。制作成本低廉,适合推广。

 

Free mouse

Computer Sciences

Huang Rui 16,No. 24 Middle School of Chengdu

The purpose of this project is to invent a kind of mouse that can be used freely without the fixed support such as a table, so that it may be applied in more jobs and reduce the users’ fatigue. Its main characters are low cost, acceptable to more people without changing their former habits when using it.

There are two ways in making this kind of mouse. One is to alter the former cursor that scans a fixed plane into one that scans a ball surface which moves together with it. The “universal axis” that is particularly designed supports the aberrant-barycenter ball which is fixed under the cursor. The cursor, via the human hand, will obtain relative displacement away from the ball surface, thus realizes the operation of the mouse. The other way involves aberrant-barycenter wheels, which are stalled vertically, and a mechanical electronic mouse raster axis. The two devices are connected through a rate changeable riving system. With the help of human hand, the relatively stationary wheel drives the raster to operate.

Considering the time, the free mouse designed by above first method operates easy and accurate. It can be used with or without a fixed support. For example, we can use it either dependently e.g. at work, for drawing and games, or independently such as in sofa, bed or for multi-media display. What’s more, the users need no special training in order to manage it freely with no trouble. Therefore, it may greatly reduce the users’ fatigue caused by long time work.
