Virtual reality (VR) based surgical simulators have been developed in order to fulfill the demands for improving quality of medical education and training. VR simulators enable to record information about expert's procedures in real time, and therefore may allow trainees to learn the skill though haptic device. However, sharing haptic information between skilled surgeons and trainees on surgical procedure is technically a difficult problem.
This study proposes methods for sharing haptic information between two persons in manipulating virtual elastic objects which physically simulate organ behavior. Our methods visualize depth information of recorded 3D position of manipulators and allow adjusting replay speed. The experiments were done to confirm the performance of the proposed methods in mimicking basic manipulation tasks. We conclude that our framework allows the user to trace 3D recorded position more accurately, which contributes to haptic information sharing in manipulating elastic objects.
