Analysis a large amounts of data acquired by a accelerometer embeded in a handheld device for figuring out the characteristics of the acceleration samples. In order to get a higher precision result of displacement after twice integration, samples are imposed a series of filtering and amendments on the basisi of the application. While de-noising the noise inducted by the accelerometer infrastructure, a dynamic adjustment mechanism is introduced to adust the filter parameters. That makes the stillness detection algorithm more effective. Experiments show that although the robustness needs to be improved, the algorithm has reached a good accuracy, this research lays a foundation for further study.
