In this study, a new modified independent modal space control (IMSC), which relaxes the fundamental hardware limitation of IMSC, is suggested to handle vibration control problems using a virtual passive controller. This method has adapted a new stable switching algorithm between controlled modes and a virtual vibration absorber as a virtual passive controller in the independent modal space. It has been found that the new modified IMSC suggested in this paper, which can reduce the number of actuators, is shown to be simple and efficient in a realistic example of vibration control of a cantilever beam.

In this paper, we present a haptic virtual exhibition space that allows users to interact with 3D graphic objects not only through the sense of sight but also through the sense of touch. The haptic virtual exhibition space offers users in different places some efficient ways to experience the exhibitions of a virtual musical museum using the basic human senses of perception, such as vision, audition, and touch. Depending on 3D graphic objects, we apply different properties to let those feel realistic. We also provide haptic device based navigation which prevents users from rushing between various interfaces: keyboard and mouse. The haptic virtual museum is based on Client-Server architecture and clients are represented in the 3D space in the form of avatars. In this paper, we mainly discuss the design of the haptic virtual exhibition space in detail and in the end, we provide performance analysis in comparison to other similar applications such as QTVR and VRML).

Tangible user interfaces have attracted strong attention in the HCI(Human and Computer Interface) community for their ability to take advantage of skills humans develop in the real world. We are developing "tangible media aided design system" which employs physical objects i.e., brick as interfacing media for 3D graphic modeling. This system is targeting for persons who are afraid of experiencing 3D graphic modeling and virtual space, or have a sense of reluctance in approaching to them. Our approach suggests the easiest way for people to experience computer system and virtual space carefree while developing and improving their space sense. This work is one of initial explorations of media aided design system using tangible user interfaces.

The purpose of the study was to identify key design features of virtual reality with head-mounted displays (HMD) and touchless interface for the hearing-impaired and hard-of-hearing learners. The virtual reality based training program was aimed to help hearing-impaired learners in machine operating learning, which requires spatial understanding to operate. We developed an immersive virtual learning environment prototype with an HMD (Oculus Rift) and a touchless natural user interface (Leap Motion) to identify the key design features required to enhance virtual reality for the hearing-impaired and hard-of-hearing learners. Two usability tests of the prototype were conducted, which revealed that several features in the system need revision and that the technology presents an enormous potential to help hearing-impaired learners by providing realistic and immersive learning experiences. After the usability tests of hearing-impaired students' exploring the 3D virtual space, interviews were conducted, which also established that further revision of the system is needed, which would take into account the learners' physical as well as cognitive characteristics.

This study shows that clothes are made just the same as the real thing in the virtual space through 3D digital technology. This study is significant to expand the area of fashion design in the virtual space. This study analyzes the practical use of the third dimension computer graphics in the aspect of fashion, and it is proposed the 3D fashion design simulation in the virtual space used on 3D studio max, poser, photoshop program according to fashion design process. The main design concept is "temporary bridge" from rainbow. "Temporary bridge" is a rainbow bridge which connects nature, man and technology, and also the past, present, and future. This study is supposed six fashion design in accordance with three sub-theme under main concept by changing rotor and texture used on 3D simulation. The conclusion are as follows : First fashion design process, which consists of design conceptualization, design definition, and computer design process, composed of body modeling, clothing modeling, texture mapping, rendering by lighting and camera establishing are compared. Second, fashion design process is applied to digital technology. Third, the method of body modeling is both that of direct modeling in 3D Studio Max and that of importing DXF file from poser. And the method of direct clothing modeling in 3D Studio Max are two methods, polygon modeling and nurbs modeling. Polygon modeling is more satisfied than nurbs modeling in the aspect of expression to clothing and round face. Forth, this study applies textures and colors transformed by photoshop on manufactured 3D Clothes. According to this result, fashion designers are able to confirm a customer or client in their design minds viewing 3D simulation by various textures. colors and angles. It is able to advance digital fashion show in the future.

Modem society is information oriented with countless people needing quick reliable information. They also wart to be freed from the limitations of reality such astime and space and experience the world of imagination as if it was reality. Design is creating something out of nothing which has an innate sense of virtual within it. Since it is a process of bringing an imagingnation or an image to life, it can be described as the realization of virtuality. there are many ways in which computer adapted methods were utilized for design up to now. With the advance of computers, the process of desinging became efficient, visually complex and much easier. Undoubtedly, computer is a powerful hardware an design and furthermore, find a way to maximize the presence and to actively incorporate this in designing. The virtual reality system can be widely applied to environmental design to provude a high quality design and enhance the feeling of reality through imitation experiments. Computer simulation such as virtual reality systems is expected to be used widely in environmental design.

As the interest in home furnishing becomes more focused due to the increase of small-sized households, the need for a virtual simulation system for this purpose is increasing. However, in the case of existing virtual simulation systems, simulation is performed using a virtual object in a virtual space, so accurate simulation results can not be derived. In the case of a simulation using an augmented reality, Thereby causing inconsistency in space. In this paper, we propose a system that performs the home furnishing simulation by modifying and enhancing objects in the process of matching feature coordinates of real space.

The relevance between organisms and their external environment covers everything including humans, natural and artificial surroundings, regarding which academic and scientific understanding has continued. Relevant elements established by inter-dependence between humans and environment and the unity of life should be translated from the perspective of a whole, not of unit elements or reduction. That is, a space is formed by its own program and assumes sustainable relevance based on interactions between internal and external spaces, not building an independent system. The present study aims to present the feasibility of a potential mutant space formed by invisible arenas between individuals and evolutionary space formation based on an ecological paradigm Accordingly, this study suggested that evolutionary attributes as the major power source of biological changes could verify the virtual multiplicity of a new space formation, and that the potential form generation of hybrid mutant space of emergence and infinite formative capability could be supported. The suggestions made here will hopefully contribute to extending applicability of evolutionary space generation in the field of space design. To derive the potential mutant forms from biological space, a preliminary study was conducted regarding the characteristics of evolutionary form generation. For the purpose of this study, three evolutionary perspectives of reproduction, mutation (variation) and selection were taken. First, the theory of evolution was defined and characterized. Also, the relevance between the characteristics generated and hybrid mutant space was analyzed to consider relevant characteristics. The present study helped to understand that the hybrid mutant space had an evolutionary space structure based on a biological paradigm. It was also found that the mutant space structure built by mutant polymorphism assumed a systematic correlation between space and environment.
