    • 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.
    • 公开了一种惯性装置,其包括惯性传感器单元,其被配置为产生表示保持惯性装置的目标的运动的输出; 存储单元,被配置为分别存储与由惯性传感器单元生成的不同输出相关联的因子; 生成单元,其被配置为通过使用与由惯性传感器单元生成的输出相对应的因子之一来生成表示惯性装置在预定时间段内的速度变化的波形; 组合单元,被配置为将波形与由生成单元生成的一个或多个先前波形组合; 以及估计单元,其被配置为使用从所述组合波形获得的速度来估计所述惯性装置当前所在的位置。
