Study of Input System based on MEMS accelerometers

This paper introduces a new computer input device system. The system uses accelerometers as sensitive sensor, and the technology of wireless data transmitting and Universal Serial Bus (USB) are used to implement the system. This system includes two subsystems: transmitting subsystem and receiving subsystem. The paper describes work principle, the software design and hardware design of the input system, which include the used accelerometers, the microprocessor and the transmitting module. And the first generation of prototype is also given in this paper. Lastly, we give a design about 3D model based on accelerometers and validate it by experiment.
