Haptic devices synchronization into a software simulator

In this paper is presented the design and developing process of a software simulator that allows both a pre-surgical planning and training future physician about anatomy and liver damage. For this it was made a design three-dimensional (3D) liver and was added properties of soft tissues in order to have a simulator surgery as realistic as to provide a complete answer and complex palpation by devices Geomagic Touch X and Phantom Omni. It highlighted the acute need for such simulator in medicine in general and surgery in particular, and its advantages over traditional methods of learning. Emphasis was placed on the use of virtual reality and haptic feedback to improve the realism of the simulator. The final goal was the synchronization between two or more haptic device using events to acquire more feedback information in the real time. Experiments conducted using different obj flies representing normal liver, hepatic liver, cirrhosis liver and cystic liver demonstrated the reliability and the robustness of the proposed method. The next step will involve the usage of Augmented Reality and Virtual Reality to provide training to physicians and healthcare staff.
