Fashion brands have traditionally conveyed emotions through brand image and images such as fashion photos; however, fashion films play an important role in conveying emotion to consumers due to changes that have resulted from the development of digital technology. This study investigates haptic perceptions in fashion films based on Laura Marks' theory. The study concurrently conducted literature and case studies. Haptic and is a condition of touching an object without actually touching it. Marks describes haptic theory as an embodied perception of physical effects that occur as images affect the body. Haptic perceptions that cause a sense of touching when looking at a fashion film can be understood as a formality embodied in the body of the object and spectator created by the object and spectator's clothing experience. Our bodies and apparel can be seen as being perceived and imprinted in our bodies by constantly experiencing and maintaining relationships in an inseparable relationship. Thus, when we look at fashion films, the haptic image invites feeling embodied in our body and provide a haptic perception. As a result, factors for the haptic perception in fashion film are ambiguity of images, fetish image, and non-narrative. Fashion companies are expected to make active use of haptic elements as an era of artificial intelligence arrives and the size of the e-commerce market grows.

A haptic interface can be a passive system with virtual coupling as a filter virtual coupling has been designed for satisfying passivity. However, it affects transparency of haptic interface as well as stability. This paper suggests new design criterion of a haptic interface controller by considering transparency. As a result, sampling time and the range of impedance or admittance should be considered as well as virtual coupling for desired performance of hapticdisplay. And experiments show that the suggested design criterion can be applied successfully for desired performance.

기존에 제안했던 실감가상시작을 위한 햅틱 다이얼 시스템을 개선하여 보다 다양하고 세련된 햅틱 효과를 주는 시스템을 제안한다. 제안된 시스템은 사용자가 실제 제품을 조작하는 듯한 느낌을 얻을 수 있도록 힘의 세기에 따른 사운드의 변화를 주며, 미리 디자인된 햅틱 효과를 GUI부 화면에서 선택하여 실시간으로 변환할 수 있다. 또한 그래픽으로 표현된 햅틱 효과에 대해 힘의 세기나 노치의 간격을 편집할 수 있다. 햅틱 다이얼에는 실제 제품에 사용되는 여러 종류의 다이얼 노브를 탈부착할 수 있어서 사용자가 실제와 같은 느낌을 받을 수 있다. 제안된 시스템은 TCP통신으로 모터부와 GUI부가 정보를 주고받기 때문에 원격 제어가 가능하다. 이 시스템은 햅틱 효과 출력 장치일 뿐만 아니라 입력 인터페이스로 사용될 수 있으므로 그 활용 범위가 넓다.

This paper deals with a Capstone Design project which is a wearable haptic wrist massage device design carried out within the 'Designeer' education program. Following design thinking process is recommended throughout a year in order to ensure a desirable, feasible and viable product. Dealing with a real problem of the field requires open-minded and flexible attitudes both from students and professors. Integrating design in an engineering project does not mean always making better looking product. User experience design allows wider opportunity to engineers to deal with design. A case study of developing a wearable wrist massage device shown in this paper demonstrate haptic design and how haptic properties can be optimized to offer best user experience of hand massaging. This study identified that starting lateral pressure movements from the center in larger area using air tubes gives better feeling as self-massage using wrist wearing devices.

This paper proposes a new haptic cue vehicle accelerator pedal device using magnetorheological(MR) brake. As a first step, an MR fluid-based haptic cue device is devised to be capable of rotary motion of accelerator pedal. Under consideration of spatial limitation, design parameters are optimally determined to maximize control torque using finite element method. The proposed haptic cue device is then manufactured and integrated with accelerator pedal. Its field-dependant torque is experimentally evaluated. Vehicle system emulating gear shifting and engine speed is constructed in virtual environment and communicated with the haptic cue device. Haptic cue algorithm using the feed-forward control algorithm is formulated to achieve optimal gear shifting in driving. Control performances are experimentally evaluated via feed-forward control strategy and presented in time domain.

햅틱 장치는 기존 장치대비 보다 편리하고 정확하며 직관적 조작이 가능한 인간-기계 교류 장치이다. 이 연구의 목적은 햅틱 장치의 색상을 독립적인 설계 변수로 고려한 설계 인자의 운전자 반응을 정의하는 것이다. 본 논문에서는 기존의 촉각 피드백을 이용한 햅틱 장치의 인지능력을 증가시키는 방법에 대하여 연구하였다. 기존의 차량용햅틱 장치에 색상 피드백을 더한 루미노 햅틱 디바이스를 이용하여 사용성 평가를 실시하였다. 감성 분석을 통하여 운전자가 갖는 햅틱 디바이스에 대한 감성분석을 도출하였다. 결과적으로 운전자를 만족시키는 설계 방향의 제안이 가능하였다.

Non-contact judgment and evaluation for products are increasingly needed along with a rapid environmental change in fashion that sows urgency in the need to implement services that allows users to judge and experience a tactile sense in a fashion product without actual contact. Technological development is required to provide users with syn-aesthetic experiences that integrate the visual, tactile and the auditory. There is also a need to conduct research to increase immersion that provides users with ICT-related experiences communicated through fashion images. The study analyzed demands for haptic communication technology by Korean users in immersive VR fashion product shopping. Accordingly, it defined haptic communication through literature research, investigated immersion in the VR environment and conducted in-depth interviews for haptic communication applicable to VR shopping. Findings show that hedonic reactions by fantasy, emotion and fun function are an important motive in selecting VR shopping. VR fashion product shopping steps were divided into 4: move to store, search in store, search of product and purchase based on offline store shopping experience. It defined the haptic communication by steps and analyzed the types of the haptic feedback to be implemented. The study results provide basic data for developing haptic communication technology that can enhance e a sense of the presence and immersion experiences that can help lay a groundwork for pilot studies on the convergence of the virtual and the real.

Fashion films with screen limits have a way of changing communication methods through sensorial organs in order to go beyond limits. This study shows that such change is possible if fashion films are based on haptic factors. This study examines haptic factors of fashion films from the three perspectives of filming factors of different shot size, synesthetic, and cinematic screen methods. First, when the subject to be emphasized is enlarging, the observer comes to project themselves to the situation and incurs a haptic sensation. Second, when associating an experience by personal recollection or social customs when more than two senses are stimulated simultaneously, haptic sensations, triggered by multiple senses, takes place. Third, a blurred image shows haptic sensations through inducing observers to see into the meaning of a shot. As a result, the senses of the observer enlarge and enhance a communication ability through absorbing and accepting a fashion film. Furthermore, fashion films are effective in understanding the cultural forms of the age.

Realistic Modeling is to maximize the reality of the environment in which perception is made by virtual environment or remote control using two or more senses of human. Especially, the field of haptic rendering, which provides reality through interaction of visual and tactual sense in realistic model, has brought attention. Haptic rendering calculates the force caused by model deformation during interaction with a virtual model and returns it to the user. Deformable model in the haptic rendering has more complexity than a rigid body because the deformation is calculated inside as well as the outside the model. For this model, Gibson suggested the 3D ChainMail algorithm using volumetric data. However, in case of the deformable model with non-homogeneous materials, there were some discordances between visual and tactual sense information when calculating the force-feedback in real time. Therefore, we propose an algorithm for the Volume Haptic Rendering of non-homogeneous deformable object that reflects the force-feedback consistently in real time, depending on visual information (the amount of deformation), without any post-processing.
