Abstract. Despite technological advances in minimally invasive surgery (MIS)
in recent years, 3D visualization of the operative field still remains one of
greatest challenges. In this paper, the effect of three visualization techniques
including conventional 2D, 2D with enhanced depth cue based on shadow, and
active 3D displays for novices with no prior adaptation to laparoscopic
visualization techniques has been analyzed. A wavelet based paradigm is
proposed which offer important insights into the effect of depth perception and
visual-motor compensation when performing MIS instrument maneuvers. The
proposed method has shown to be advantageous over conventional end-point
methods of laparoscopic performance assessment as important supplementary
information can be derived from the same trajectories where conventional
measures fail to show significant differences.
