IMU Logger のアプリ分析 12月3日

A no frills intertial measurement unit logger from your device accelerometer, gyroscope and magnetometer. FEATURES: Visualise accelerations, rotations and the magnetic field on screen and update accelerometer X,Y, and Z value in the notification bar (the logger runs as a foreground service) Save accelerations to device into /dataLogger/accLog /dataLogger/gyrLog and /dataLogger/magLog as tab-separated text files (the folders will get created if needed). Time stamps saved as UTC (milliseconds since midnight 01/01/1970) in your current location. Requests fastest sample rate available on the device. My current smartphone (Huawei Honor 8) returned values at 100 Hz sampling rate, and the sample rate seemed to be constant. On previous smartphones I have had varying sample rates (resample with interpolation to get constant sample rate when analysing).
