7 FUTURE WORK
For the next future, it is planned to further study the
attitude estimation done by the integrated DSP inside
the IMU. Therefore, we are currently working on a
new design for a hip-mounted PDR unit. Further-
more, in terms of algorithms design, we are work-
ing on a classification of typical movement patterns to
improve and optimize the performance for a specific
application scenario. Based on the movement classi-
fication the alignment procedure of the IMU will be
further improved. Also, the initialization process of
the anchor nodes and cooperative approaches will be
evaluated further.
