``햅틱의 시대 Haptic age``가 도래했다고 말하고 있다. 오늘날 햅틱 인터페이스들은 우리의 일상 곳곳에 들어와 시간과 공간을 연결하는 가장 필수적인 기술이자 미디어로서 기능하고 있다. 햅틱 기술발전을 가속화하여 머지않아 인간 손의 범위를 넘어 인간 삶의 생물학적인 조건들에 영향을 미칠 것으로 예측되고 있다. 이 같은 햅틱 기술의 비약적 발전에 대해 인문학이 접근하고 대응하는 연구는 아주 미미한 상황이다. 본 연구는 햅틱의 기술과 그것의 미디어적 활용에 직면하여 인문학적 논의를 이끌고자 공학과의 상호 융합적 연구를 통해 접근하고자 한다. 이를 위해 우선 인간 커뮤니케이션을 위한 촉각적 구조에 대해 정의하며, 이와 함께 촉각이 가지는 인간 커뮤니케이션에서의 문제성을 다루게 된다. 다음으로는 현재의 햅틱 기술들의 위치와 그 한계들에 대해 논의하며, 마지막으로는 이러한 기술들에 대해 인문학은 어떤 문제제기와 차후 기술발전을 위해 무엇을 제안할 수 있는지를 논의하게 될 것이다. 결과적으로 본 연구는 공학에서 전개되어 온 햅틱 기술들이 차후 인간의 촉각이 갖는 개별적이고 질적인 부분들에 대한 변화와 함께 인간존재에 대한 본질의 문제를 위협할 수도 있다는 점을 인식하고 이를 사위어 내기 위한 방법을 모색해야함을 설명하고 있다. It is said that the haptic age has come. Today`s haptic interfaces function as an essential technology and medium which connects our everyday time and space, so that in the near future those technologies would more strongly influence the biological conditions of our life beyond the limitations of human nature. However, humanistic studies on such rapid development of haptic technologies have been insignificant. This paper aims to initiate further humanistic discussion on the current state of haptic technology and its media applications throughout an interdisciplinary research combining engineering science. First of all, this study will provide a definition of the haptic structure of the human communication as well as the scope of the problem-related human communication based on the haptic sense, and then will analyze both the current status and the limit of haptic technology. Lastly, this paper will present the perspective of humanities for today`s haptic technology to prepare a future evolution. In consequence, the objective of this study is not only to examine the engineering development of haptic communication technologies that have derived from the devotional sacrifice of individual and qualitative haptic sense of human but also to emphasize the necessity of integrated thinking between humanities and engineering science.

In this study, we designed a special education assistive technology system consisting of Haptic-display providing visual information converted to tactile information and educational contents. To design a special education assistive technology system appropriate for special education environment, we derived system requirements by surveying teachers and visually impaired students, and we also analyzed tactile information perception characteristics of visually impaired students based on in-depth interviewing. In addition, we analyzed current special education resources and special education technology devices, and we designed a new special education technology system appropriate for visually impaired special education environment based on the analysis results. We designed the Haptic-display device and its user interface considering of tactile information perception characteristics of visually impaired students and their requirements, and also designed educational contents producing program that can automatically translate text, equation and visual information to tactile information. We expect that the proposed system can maximize learning efficiency of visually impaired students. 본 연구에서는 시각장애인에게 시각자료를 촉각정보로 변환하여 제공할 수 있는 햅틱디스플레이(Haptic-display) 장치와 이를 위한 교육 콘텐츠로 구성된 특수교육 보조공학시스템을 설계하였다. 특수교육 환경에 적합한 특수교육 보조공학시스템 설계를 위하여 맹학교 현직 교사들과 전맹학생들을 대상으로 특수교육 보조공학시스템에 대한 요구사항을 분석하였고, 시각장애학생들의 촉각정보인지 특성을 심층면담을 통해 분석하였다. 또한 현재 활용하고 있는 특수교육 자료 및 특수교육 보조공학장치에 대하여 분석하였으며, 분석된 자료를 바탕으로 시각장애교육 환경에 적합한 특수교육 보조공학시스템 설계에 반영하였다. 햅틱디스플레이 장치와 사용자 인터페이스는 시각장애학생들의 촉각정보인지 특성과 요구사항을 고려하여 설계하였으며, 장치에 필요한 교육 콘텐츠 저작 프로그램은 문자 및 수식 점역기능과 시각자료의 점역기능 등이 가능하도록 설계하였다. 제안한 시스템은 시각장애학생들의 학습능률을 극대화시킬 것으로 기대된다.

Application of haptic technology has been increasing steadily over the past several years. The fundamental physics of haptic technology lies in the interaction between the finger and the object. In this sense, the frictional behavior at the contact interface needs to be clearly understood in order to optimize the performance of haptic-based systems. In this work the frictional behavior of a finger tip with respect to various sliding conditions and materials such as paper, wood, leather, glass, metal, and plastic was assessed. A custom-built experimental apparatus was used to measure the friction and normal forces as the finger was pressed and slid against a specimen surface. Friction experiments were performed under both dry and wet conditions. Experimental results showed that friction coefficient ranged between 0.39 to 2.47 depending on the sliding condition and material. Also, the ridge structure of the finger tip was identified to have a significant influence on the frictional behavior.

Necessity of Anatomy Education for Dental School Students Utilizing 3D and Virtual Reality Technologies: A Narrative Review

Yeon-Hee Lee(이연희) 대한치과의사협회 2024 대한치과의사협회지 Vol.62 No.4

Members of dental academia are eager to embrace innovative tools for anatomy education. The proliferation of technological resources has facilitated the integration of virtual systems into dental and medical education. This is considered paramount for communicating the anatomical knowledge essential for safe and competent medical practice. Among these tools, three-dimensional (3D) anatomy models, virtual reality (VR) simulations, and haptic technologies are pivotal for educating students and training healthcare professionals. This narrative review discusses these topics based on published outcomes from the past decade, emphasizing their potential in anatomical learning and clinical practice, particularly during the COVID-19 pandemic. Substantial interest and positive impacts have been reported by educators and students regarding the utilization of 3D VR. 3D VR enables precise and high-resolution representations of organ structure, vascular formation, and nerve distribution. It enriches anatomical, clinical, and radiological learning and familiarizes individuals with the anatomical and radiological features of real patients. Furthermore, 3D VR ensures the continuity of anatomical and surgical training through online platforms, making the strategic deployment of these devices especially pertinent during quarantine. Therefore, dental education and clinical applications using 3D VR, augmented reality, and haptic technology are expected to become an unstoppable trend.

김현민(Hyeon Min Kim),김갑순(Gab Soon Kim) Korean Society for Precision Engineering 2013 한국정밀공학회지 Vol.30 No.3

This paper describes the development of a cylindrical-object grasping force measuring system applied haptic technology to measure the grasping force of strokes patients’ fingers and other patients’ paralyzed fingers. Because the cylindrical-object and the force measuring device of the developed cylindrical-object grasping force measuring system are connected with the electrical wires, patients and their families have difficulty not only measuring the patients’ grasping force using the system but also knowing their rehabilitation extent when using it. In this paper, the cylindrical-object grasping force measuring system applied haptic technology was developed, and the cylindrical-object grasping force measuring device sends data to the rehabilitation evaluating system applied haptic technology by wireless communication. The grasping force measurement characteristic test using the system was carried out, and it was confirmed that the rehabilitation extent of the patients’ paralyzed fingers and normal people fingers can be evaluated.

조영훈,홍성혁 한국문화재보존과학회 2019 보존과학회지 Vol.35 No.1

This study examined the applicability of digital technologies based on three-dimensional(3D) scanning, modeling, and printing to the restoration of damaged artifacts. First, 3D close-range scanning was utilized to make a high-resolution polygon mesh model of a roof-end tile with a missing part, and a 3D virtual restoration of the missing part was conducted using a haptic interface. Furthermore, the virtual restoration model was printed out with a 3D printer using the material extrusion method and a PLA filament. Then, the additive structure of the printed output with a scanning electron microscope was observed and its shape accuracy was analyzed through 3D deviation analysis. It was discovered that the 3D printing output of the missing part has high dimensional accuracy and layer thickness, thus fitting extremely well with the fracture surface of the original roof-end tile. The convergence of digital virtual restoration based on 3D scanning and 3D printing technology has helped in minimizing contact with the artifact and broadening the choice of restoration materials significantly. In the future, if the efficiency of the virtual restoration modeling process is improved and the material stability of the printed output for the purpose of restoration is sufficiently verified, the usability of 3D digital technologies in cultural heritage restoration will increase.
