    This paper describes an improvement to our previously proposed laparoscopic training system that was designed to improve surgical skill transmission by allowing surgical trainees to replicate the movements of skilled surgeons dis-played on a monitor. However, we found that with this system, the precision of followability in the depth direction was low in comparison with that on the monitor in the planar direction. Herein, to improve the reproducibility of the forceps position and present clues for depth perception, we provide learners with haptic feedback by reproducing the viscera wall using an encounter-type haptic presentation device.

    In our learning system (OITORE Advance), high learning effect was confirmed by using teaching materials using porcine intestines. However, because the environment inside the abdominal cavity is different between pigs and people, there are scenes with different surgical procedures and surgical skills. Therefore, not all the learned skills are applied in human surgery. Therefore, in this paper we changed teaching materials from pig to human and adjusted the system accordingly.
