dc.description.abstractIn this paper we present an adaptive step length
estimation algorithm with the awareness of the inertial
measurement unit (IMU) location for pedestrian dead
reckoning (PDR). The developed PDR is assumed to be
embedded in mobile devices. Thus it is supposed that the
IMU can be equipped on two locations; on a waist belt or
in a trouser pocket of the pedestrian. In this paper the step
length is estimated by a simple linear combination of a
constant, walking frequency and acceleration variance. It
is investigated that the step length estimation parameters
should be changed if PDR is equipped on different parts
of the human body. Otherwise it can cause considerable
error in the step length estimation. In order to enhance the
performance of the step length estimation algorithm, we
present to adaptively estimate the step length according to
the PDR equipped location. And then the walking
distance of the user is calculated in real-time. The
performance of the proposed algorithm is verified through
the actual walking tests.
