We present a low-cost six-degrees of freedom violin and
bow pose-tracking system. The infrared and depth streams
of an infrared-based Microsoft Kinect Mbox One depth
camera are utilized to track the 3-dimensional position of 6
infrared markers attached on the violin and the bow. After
computing the bow pose on the violin coordinate system, a
number of bowing features are extracted. In order to evaluate
the system’s performance, we recorded 4 bowing exercises

the system’s performance, we recorded 4 bowing exercises
using simultaneously our system along with a commercial
two-sensor 3D tracking system based on electromagnetic
field (EMF) sensing. The mean pearson coefficient
values were 0.996 for the bow position, 0.889 for the
bow velocity, 0.966 for the bow tilt, 0.692 for the bowbridge
distance and 0.998 for the bow inclination. Compared
to existing bowing-tracking solutions, the proposed
solution might be appealing because of its low cost, easy
setup and high performance.
