【摘要】 该文章介绍了一种新的电脑无线输入系统,使用MEMS微加速度计作为系统的敏感元器件。该输入系统包括发射端和接收端两个子系统。文章分别从工作原理、软硬件设计等方面介绍了该输入系统,包括所使用的微加速度计、微处理器和传输模块,并给出了输入系统的第一代实际PCB原型。并且在二维的基础上扩展了微加速度计在三维的应用,设计了一个新的三维模型,并进行了试验的验证。更多还原

【Abstract】 This paper introduces a new computer input device system.MEMS accelerometers are used as the sensitive sensor and the technology of wireless data transmitting and Universal Serial Bus(USB) are used to implement multi-functional input.This system includes two subsystems:transmitting subsystem and receiving subsystem.The paper describes the work principle of accelerometers,the software design and hardware design of the input system,which include a embedded system,microprocessor and the wireless data transmission module.At last,the paper also designs a new 3D accelerometer model to extend the application of the input system in 3D environment and the tests validate the accuracy of the 3D model.更多还原
