  This is the preprint version of our paper on REHAB2015. A balance measurement
software based on Kinect2 sensor is evaluated by comparing to Wii balance board
in numerical analysis level, and further improved according to the
consideration of BFP (Body fat percentage) values of the user. Several person
with different body types are involved into the test. The algorithm is improved
by comparing the body type of the user to the 'golden- standard' body type. The
evaluation results of the optimized algorithm preliminarily prove the
reliability of the software.
