基于MMA7455L加速度鼠标的研究
Research of Acceleration Mouse Based on MMA7455L
【摘要】 针对传统鼠标定位必须依靠其所在工作平面的特点,开发出一种利用三向加速度传感器MMA7455L作为移动信号采集的鼠标,使得该鼠标可以脱离平面的束缚正常工作。针对鼠标在PC机屏幕上移动是在平面上的特点,提出了移动补偿算法,可以真正的实现鼠标由平面转向三维空间的自由操作。应用结果表明,该算法与硬件设计能够满足鼠标正常工作的应用要求,并具有性能稳定,成本低廉等优点。
【Abstract】 The traditional mouse position to rely on the characteristics of their plane in the work developed by means of a three-accelerometer MMA7455L mouse as a mobile signal acquisition,making the mouse be freed from the shackles of print work. For the PC-screen,mouse movement is in the plane of the characteristics of proposed motion compensation algorithm,the realization of the mouse can actually shift from two-dimensional to three-dimen-sional space to operate freely. Application results show that the algorithm and hardware design meet the application in requirements of the mouse work,and the design has stable performance,low cost.
