The possibilities of computer graphics, imitation of physical properties of various materials, realistic skeleton animation, complementary systems and virtual reality, combined with sensors for real-time motion tracking, make it possible to create medical simulators with simulation of a wide range of surgical pathologies and integrate into the virtual environment of the operator. The basis of this development is the task of creating a new mode of interactive training with the use of Motion Capture and Hand Capture technologies (real-time motion tracking technology). The aim of the study was formation and development of manual skills for increasing the efficiency and automation of students’ independent learning activities. Object and methods. The basis of the development is the creation of a virtual library of interactive three-dimensional anatomical «head-neck» models, as a template version of the pathology, import into an interactive threedimensional scene of computed tomography (CT) data and import into the virtual environment of operator movements. One of the main training elements is the students’ clinical projects. Results and discussion. The method is aimed at developing automation for surgical manipulations, the creation in the subconscious of the operator stereoscopic representation of the topography of organs and systems without a tactile component. The further development of such approaches will allow the broadcast in the interactive environment of a three-dimensional record or duplicate of the surgeon’s hands movements directly from the operating room and combine with the movements of the hands of the learner. Conclusion. Using the interactive environment allows you to simulate virtually all surgical pathologies, and the use of medical scanner data will allow you to move away from the template version of the pathology. Integration into the virtual environment of the Motion Capture and Hand Capture system will allow you to develop manual skills practically with any type of surgical pathology without significant economic costs.
