Article Citation - WoS: 8Citation - Scopus: 7The Underlying Reasons of the Navigation Control Effect on Performance in a Virtual Reality Endoscopic Surgery Training Simulator(Taylor & Francis inc, 2019) Cagiltay, Nergiz Ercil; Ozcelik, Erol; Berker, Mustafa; Dalveren, Gonca Gokce MenekseNavigation control skills of surgeons become very critical for surgical procedures. Strategies improving these skills are important for developing higher-quality surgical training programs. In this study, the underlying reasons of the navigation control effect on performance in a virtual reality-based navigation environment are evaluated. The participants' performance is measured in conditions: navigation control display and paper-map display. Performance measures were collected from 45 beginners and experienced residents. The results suggest that navigation display significantly improved performance of the participants. Also, navigation was more beneficial for beginners than experienced participants. The underlying reason of the better performance in the navigation condition was due to lower number of looks to the map, which causes attention shifts between information sources. Accordingly, specific training scenarios and user interfaces can be developed to improve the navigation skills of the beginners considering some strategies to lower their number of references to the information sources.Conference Object Simulations for Surgical Education: a Case Study for Endoneurosurgery(Iated-int Assoc Technology Education A& development, 2015) Berker, Mustafa; Cagiltay, Nergiz Ercil; Isikay, IlkayToday, introduction of the microscope and later the extensive use of the video camera have changed the way operations are performed which have replaced the direct vision by a video image. These types of surgical techniques are generally called as minimal invasive surgery (MIS). Laparoscopic surgery and endoscopic surgery fall in this category. These new technologies require some additional skills to be gained during the surgical education and training programs. Most of the traditional surgical training takes place in the operating theater under the supervision of an experienced surgeon which does not allow any try-and-error type of learning, and does not tolerate errors. Hence, alternative educational methods by providing try-and-error type of learning are a critical for medical education. This study presents a simulation environment developed specifically for the pituitary surgery operations. The simulation environment composed of two main parts: the skill-based education and the procedure-based education for the novice surgeons. This study shows the design and implementation of educational modules developed to provide try-and-error type of educational environments as a case study on pituitary surgery operations.
