摘要：For every new accelerometer sample, we compute thestandard deviation of the magnitude of the accelerationover a sliding window (w) of samples. The window slidesby one sample for each computation. If the standard de-viation in a window exceeds a threshold (a), we detectmovement. When the standard dev 阅读全文
