We propose 'the haptic primitive' for haptic rendering without the need to solve complicated parametric equations. To develop 'the haptic primitive', we adopted "the God-Object Method" as a haptic rendering algorithm and applied 'Constructive Solid Geometry' to manage haptic objects. Besides being used in the 'ghost library' of $PHANToMTM^{TM}$ our method can be used as a basic component for developing tools and libraries that aim to simplify haptic modeling. It can also be applied to tactile display modules and temporal display modules. Ultimately it can be developed into a one-stop haptic modeling tool that enables the user to more conveniently create a tangible CAD systems or a tangible e-ommerce system.

This paper presents a haptic display of a cooperative work between the networked multiple users. Excluding the possibility of large timedelay among the users, it is presented the way of configuring individual haptic display systems including the computation of interaction forces, joint driving forces of haptic devices and simulation of the virtual objects. A haptic display system is developed consisting of two haptic display devices operated by two remote users and experimental results to show the validity of the proposed method are also presented.

A technology roadmap was developed for haptic interface technologies to be applied to games. Haptic interface technologies are expected to play an important role in games to provide gamers with interaction and immersive perception in near future, even though haptic interface technologies have been less studied than other perception-related technologies with respect to games. Information on two types of haptic interfaces - portable and desktop - and their evolution processes were analyzed in terms of technological demands. Haptic feedback technologies to realize these demands were inspected with the time frame and haptic feedback technologies were derived using a technology tree. The technology roadmap of haptic interfaces in game was finally constructed by mapping the technological demands in time with game technology trends. The technology roadmap of haptic interfaces will have implications on developing haptic interfaces to be applied to many applications including virtual realities and games.

The virtual reality - haptic device is developed for the purpose used in the work that human cannot approach and that need elaborate exercises. To render haptic, the total system is constituted master, haptic device, and slave, remote manipulator. Human operates the remote manipulator. Human operates the remote manipulator relying on the hapti devices and stereo graphic. And then the force and scene of the remote manipulator is fed-back from each haptic devices and virtual devices. The feedback information gets system gain exactly. The system gain provides the most exact haptic and virtual devices. The feedback information gets system gain exactly. The system gain provides the most exact haptic and scene to human by the location, the graphic rendering and the haptic rendering algorithm on real-time. In this research, 3D haptic device is developed for common usage and make human feel the haptic when human contacts virtual object rendered by computer graphic. The haptic device is good for tracing location and producing devices because of the row structure. Also, openGL and Visual Basic is utilized to the algorithms for haptic rendering. The haptic device of this research makes the interface possible not only with virtual reality but also with the real remote manipulator.

In this paper, we determine the design criteria of haptic device considering the human haptic system and determine the design specifications. We developed a new 2DOF haptic device based on the specifications. It has the wide workspace, statically-balanced, constant inertia matrix, well-conditioned Jacobian matrix and so on. There also is not singularity point within workspace of the device. We show that it has better performance than other 2DOF haptic device in the many aspects.

Objective: The aim of this study is to investigate haptic perception related researches into three perspectives: cutaneous & proprioceptive sensations, active & passive touch, and cognition & emotion, then to identify issues for implementing haptic interactions. Background: Although haptic technologies had improved and become practical, more research on the method of application is still needed to actualize the multimodal interaction technology. Systematical approached to explore haptic perception is required to understand emotional experience and social message, as well as tactile feedback. Method: Content analysis were conducted to analyze trend in haptic related research. Changes in issues and topics were investigated using sensational dimensions and the different contents delivered via tactile perception. Result: The found research opportunities were haptic perception in various body segments and emotion related proprioceptive sensation. Conclusion: Once the mechanism of how users perceives haptic stimuli would help to develop effective haptic interactrion and this study provide insights of what to focus for the future of haptic interaction. Application: This research is expected to provide presence, and emotional response applied by haptic perception to fields such as human-robot, human-device, and telecommunication interaction.

Since the dismantling processes of building are very dangerous, there have been many studies to develop a remote operating devices using joystick. In this paper, in order to improve the operability of the dismantling actuator that is usually an excavator, a novel concept of tele-operated haptic device is proposed. Operators who use this haptic device with additional environmental sensing devices can work safely away from the dangerous sites. First, based on the concept design of the haptic device, the workspace mapping from the haptic device to the excavator is explored. Second, the kinematics which deals with the conversion from the 3 dimensional position information of the haptic device to the joint variable information of the backhoe is included. Lastly, 3D graphical simulation of both haptic device and the backhoe will be shown. This new design of the haptic device can be easily manufactured and gives the workers very convenient and transparent remote control capability.

본 논문에서는 터치스크린이 장착된 윈도우 시스템에서 촉각 피드백을 사용해 윈도우 인터페이스와 상호작용하는 방법 및 체계를 제안한다. 사용자가 터치 스크린을 통해 윈도우 인터페이스와 상호작용할 때 발생하는 주요 이벤트는 윈도우 인터페이스 메시지 필터(Windows Interface Message Filter: WIMF)에 의해 감지되고, 촉각 정보 제공기(Haptic Information Provider: HIP)를 통해 적절한 촉각 정보로 변환되어 본 연구에서 제안한 스타일러스형 햅틱 인터페이스를 통해 사용자에게 촉각 자극을 전달한다. 본 연구에서는 윈도우 환경의 주요한 조작 방법인 버튼 클릭, 메뉴 선택 및 팝업, 창/아이콘 선택 및 끌어놓기(drag & drop), 스크롤에 대하여 촉각 피드백을 구현하였다. 피험자 실험결과 촉각 피드백은 상호작용하는 인터페이스 객체가 선택되었는지에 대한 사용자의 직관을 증대시켰으며, 인터페이스 객체의 위치 및 크기 조절 시 인터페이스의 정교한 조작을 도와 사용성을 증대시켰다.

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.
