Acceleration Noise Correction for Transfer Inference Using Accelerometers on Mobile Devices

Abstract

The acceleration noise generated in the ordinary usage of mobile operating them) interferes with estimation of the means of migration devices (e.g. when taking out using accelerometers on the developed a correction method for the noise generated when users take out devices, change their posture, and operate the devices. The method uses the changes of acceleration and the operation events acquired from the operating systems of the mobile devices to detect the period of noises. The result of evaluation shows that the method using the acceleration changes improves the precision of the context inference approximately 5%, and the method using the operation events corrects the inference mistaking resting for boarding.
