Article Citation Count: 7Eye-Hand Coordination Patterns of Intermediate and Novice Surgeons in a Simulation-Based Endoscopic Surgery Training Environment(International Group for Eye Movement Research, 2018) Topalli,D.; Cagiltay,N.E.; Information Systems EngineeringEndoscopic surgery procedures require specific skills, such as eye-hand coordination to be developed. Current education programs are facing with problems to provide appropriate skill improvement and assessment methods in this field. This study aims to propose objective metrics for hand-movement skills and assess eye-hand coordination. An experimental study is conducted with 15 surgical residents to test the newly proposed measures. Two computer-based both-handed endoscopic surgery practice scenarios are developed in a simulation environment to gather the participants’ eye-gaze data with the help of an eye tracker as well as the related hand movement data through haptic interfaces. Additionally, participants’ eye-hand coordination skills are analyzed. The results indicate higher correlations in the intermediates’ eye-hand movements compared to the novices. An increase in intermediates’ visual concentration leads to smoother hand movements. Similarly, the novices’ hand movements are shown to remain at a standstill. After the first round of practice, all participants’ eye-hand coordination skills are improved on the specific task targeted in this study. According to these results, it can be concluded that the proposed metrics can potentially provide some additional insights about trainees’ eye-hand coordination skills and help instructional system designers to better address training requirements. © 2018.

E.; Information Systems EngineeringThe use of simulation techniques in medical education is an emerging topic in surgical training process, and there are limited number of studies found in this field in our country and the world. Recently, using the machine learning techniques in surgical training constitutes a new area of research. By using these techniques, cost-efficient educational tools will be developed in order to improve education efficiency and patient safety. In this scope, it is aimed to develop an intelligent support system by examining the hand movements of the experienced surgeons during a surgical education process and guide less-experienced surgeons. In order to develop this system, previously developed surgical simulation system infrastructure in ECE Project supported by Tubitak-1001 program will be used. The hand movements' data of experts obtained by special tactile devices (haptics) are analyzed with an experimental study. The results of this study aimed to improve the surgical simulation training process with the machine learning algorithm developed and therefore, provide a significant contribution to the surgical training process.Master Thesis Sanal gerçeklik, artırılmış gerçeklik kullanımını keşfetmek ve konu modelleme analiziyle diş hekimliğinde simülasyon(2023) Haıder, Syed Muhammad Nabeel; Topallı, Damla; Information Systems EngineeringSimülasyon alanındaki teknoloji gelişmeleriyle birlikte, simülasyon, sanal gerçeklik (VR) ve artırılmış gerçeklik (AR) ortamlarının tıp eğitimi alanında günlük olarak kullanımı artmaktadır. Literatürdeki önceki çalışmalar, diş hekimliği eğitimi alanında VR ve AR kullanımının öğrencilerin öğrenme ve klinik eğitimini geliştirebileceğini göstermiştir. Literatürdeki önceki çalışmalara göre, VR ve AR teknolojileri, daha etkileşimli ve ilgi çekici bir öğrenme deneyimi sağlayarak öğrencilerin öğrenme ve klinik eğitimini geliştirebilen diş hekimliği eğitiminde faydalı olarak rapor edilmektedir. VR/AR tabanlı teknolojilerin diş hekimliği eğitiminde geleneksel eğitim yöntemlerine göre daha etkili olduğu bulunmuştur. Bu nedenle, bu çalışmanın temel amacı, diş hekimliği alanında VR/AR ve simülasyon ortamlarının uygulama trendlerini anlamaktır. İlk olarak, son 10 yılın (2012-2022) 57 makalesini içeren bir literatür taraması yapılarak, diş hekimliği eğitiminde VR/AR araçlarının, simülasyonların genel bir genel bakışını sunmak ve eğitim sistem tasarımcılarının alan içinde teknoloji destekli öğrenme ortamlarını daha iyi kullanmalarına rehberlik etmek amaçlanmıştır. Ayrıca, diş hekimliği özelinde uygulama ve eğitimsel perspektifi daha kapsamlı bir şekilde anlamak için yaygın olarak kullanılan bir konu modelleme algoritması olan Latent Dirichlet Allocation (LDA), SCOPUS veri tabanından elde edilen 669 makalenin analizinde kullanılmıştır. Çalışmanın sonuçları diş hekimliğivi eğitiminde VR/AR ve simülasyon ortamlarının kullanımının mevcut durumu ve potansiyel gelecek yönelimleri hakkında değerli bilgiler sunmaktadır.Article Citation Count: 3Online Learning Perceptions amid COVID-19 Pandemic: The Engineering Undergraduates' Perspective(Tempus Publications, 2022) Eryilmaz, Meltem; Kalem, Guler; Kilic, Hurevren; Tirkes, Guzin; Topalli, Damla; Turhan, Cigdem; Yazici, Ali; Information Systems Engineering; Computer Engineering; Software EngineeringThe COVID-19 pandemic caused face-to-face education in just about all universities worldwide to shift to online education. For most students, this educational model was a compulsory first experience. In this study, the survey results are analyzed and discussed related to a group of students in the Engineering Faculty of a university in Turkey regarding their online education perceptions. Briefly summarized, the findings of the study indicate that: (a) most of the students still prefer face-to-face learning, which is also favored if accompanied by distance learning; (b) the concentration level of the students has dropped due to the concerns about the COVID-19 pandemic which affects their learning negatively; and (c) around half of the students participating in the study feel that the online exams conducted without a secure exam software, is considered unsafe. Additionally, the study's results were further extended to evaluate the questionnaire results and reported along with the suggestions of necessary actions in emergency online learning (EOL).Article Citation Count: 1A user task design notation for improved software design(Peerj inc, 2021) Ozcan, Eda; Topalli, Damla; Tokdemir, Gul; Cagiltay, Nergiz Ercil; Information Systems Engineering; Computer Engineering; Software EngineeringSystem design is recognized as one of the most critical components of a software system that bridges system requirements and coding. System design also has a significant impact on testing and maintenance activities, and on further improvements during the lifespan of the software system. Software design should reflect all necessary components of the requirements in a clear and understandable manner by all stakeholders of the software system. To distinguish system elements, separation of concerns in software design is suggested. In this respect, identification of the user tasks, i.e., the tasks that need to be performed by the user, is not currently reflected explicitly in system design documents. Our main assumption in this study is that software quality can be improved significantly by clearly identifying the user tasks from those that need to be performed by the computer system itself. Additionally, what we propose has the potential to better reflect the user requirements and main objectives of the system on the software design and thereby to improve software quality. The main aim of this study is to introduce a novel notation for software developers in the frame of UML Activity Diagram (UML-AD) that enables designers to identify the user tasks and define them separately from the system tasks. For this purpose, an extension of UML-AD, named UML-ADE (UML-Activity Diagram Extended) was proposed. Afterwards, it was implemented in a serious game case for which the specification of user tasks is extremely important. Finally, its effectiveness was analyzed and compared to UML-AD experimentally with 72 participants. The defect detection performance of the participants on both diagrams with two real-life serious game scenarios was evaluated. Results show a higher level of understandability for those using UML-ADE, which in turn may indicate a better design and higher software quality. The results encourage researchers to develop specific design representations dedicated to task design to improve system quality and to conduct further evaluations of the impact of these design on each of the above mentioned potential benefits for the software systems.Review Citation Count: 0A systematic review on classification and assessment of surgical skill levels for simulation-based training programs(Elsevier Ireland Ltd, 2023) Tonbul, Gokcen; Topalli, Damla; Cagiltay, Nergiz Ercil; Information Systems Engineering; Software EngineeringBackground: Nowadays, advances in medical informatics have made minimally invasive surgery (MIS) procedures the preferred choice. However, there are several problems with the education programs in terms of surgical skill acquisition. For instance, defining and objectively measuring surgical skill levels is a challenging process. Accordingly, the aim of this study is to conduct a literature review for an investigation of the current approaches for classifying the surgical skill levels and for identifying the skill training tools and measurement methods.Materials and Methods: In this research, a search is conducted and a corpus is created. Exclusion and inclusion criteria are applied by limiting the number of articles based on surgical education, training approximations, hand movements, and endoscopic or laparoscopic operations. To satisfy these criteria, 57 articles are included in the corpus of this study.Results: Currently used surgical skill assessment approaches have been summarized. Results show that various classification approaches for the surgical skill level definitions are being used. Besides, many studies are con-ducted by omitting particularly important skill levels in between. Additionally, some inconsistencies are also identified across the skill level classification studies.Conclusion: In order to improve the benefits of simulation-based training programs, a standardized interdisci-plinary approach should be developed. For this reason, specific to each surgical procedure, the required skills should be identified. Additionally, appropriate measures for assessing these skills, which can be defined in simulation-based MIS training environments, should be refined. Finally, the skill levels gained during the developmental stages of these skills, with their threshold values referencing the identified measures, should be redefined in a standardized manner.Conference Object Citation Count: 1Neuronavigation Systems and Passive Usage Problem(Ieee, 2015) Cagiltay, Nergiz; Topalli, Damla; Borcek, Alp Ozgun; Tokdemir, Gul; Maras, Hakan; Tonbul, Gokcen; Aydin, Elif; Information Systems Engineering; Department of Electrical & Electronics Engineering; Computer Engineering; Software EngineeringNowadays, neuronavigation systems are used in brain surgery procedures, known as a technology to help the surgeon during the operational period. However, the surgeons have faced several problems with the existing systems. Some of these problems are related to the systems software and user interfaces. In this study, such problems are examined and the "Passive Usage" term is added to the literature by establishing a connection between the problems of endoscopic surgical procedures and similar issues occurred in other domains. The passive usage problem is generalized on different domains for the first time with this study. The results of the study expected to gather up the similar passive usage problems experienced in different domains. Accordingly, the methodologies and studies that are conducted in different research areas may lead to eliminate the Passive Usage problems efficiently.Article Citation Count: 5Eye-Hand Coordination Patterns of Intermediate and Novice Surgeons in a Simulation-Based Endoscopic Surgery Training Environment(int Group Eye Movement Research, 2018) Topalli, Damla; Cagiltay, Nergiz Ercil; Information Systems Engineering; Software EngineeringEndoscopic surgery procedures require specific skills, such as eye-hand coordination to be developed.

In general, people use one hand with a superior performance compared to the other hand where that hand is preferred for performing daily activities. It is critical to understand their preference for right or left hand use, especially in cases where the skills should be improved to use both hands precisely in activities required special abilities such as endoscopic surgical operations. A better understanding of these cases will improve the quality of existing surgical education programs, and make a major contribution specifically in designing, improving and managing of simulation-based instructional technologies. In this study, the right-and left-hand preferences (handedness) of people are analyzed from the literature and a simulation-based experimental study is conducted in order to examine the performance differences of the participants while using their right and left hands. The results of this study aimed to guide the curriculum designers and instructional system developers for better designing and developing simulation-based surgical education programs.Article Citation Count: 3Understanding the Effect of Handedness on Both-Handed Task Performance: An Experimental Study based on a Haptic-Controlled, Simulation-Based Surgical Skill Training Scenario(Taylor & Francis inc, 2019) Topalli, Damla; Eyuboglu, Burak Gokberk; Cagiltay, Nergiz Ercil; Information Systems Engineering; Software EngineeringUnderstanding the performance on both-handed tasks, such as endoscopic surgery, is critical to better organize and develop appropriate instructional systems to improve the necessary skills of surgeons. However, in the literature, only a limited number of studies have investigated the effect of handedness on both-handed task performance. This study aimed to provide an understanding of the participants' performance differences while performing both-handed tasks through a haptic user interface in a simulated virtual environment specifically developed for surgical training purposes. Twenty-four surgeons attending a medical school in Turkey voluntarily participated in the study. The duration, accuracy, and collision measures were automatically recorded by software. The results revealed that the left-handed participants performed the both-handed tasks (camera: nondominant hand, tool: dominant-hand) in a significantly shorter time than the right-handed participants. This study also showed that haptic-controlled simulation-based surgical skill training systems can potentially provide measures for better understanding the individual behaviors and deliver alternative training environments specific to individual requirements.
