INERTIAL DEVICE, METHOD, AND PROGRAM

摘要

An inertial device is disclosed that includes an inertial sensor unit configured to generate an output representing motion of a target holding the inertial device; a storage unit configured to store factors which are associated with different outputs to be generated by the inertial sensor unit, respectively; a generation unit configured to generate a waveform which represents variation of velocity of the inertial device in a predetermined period by using one of the factors corresponding to the output generated by the inertial sensor unit; a combination unit configured to combine the waveform with one or more previous waveforms which have been generated by the generation unit; and an estimation unit configured to estimate a position where the inertial device is currently located using a velocity obtained from the combined waveform.
