Today, computer graphics have moved into spotlight within many related fields. The use of computer graphics in many fields as well as in design is now universalized. More than ever, those fields which utilize virtual reality are being vigorously researched and are rapidly progressing. Many advanced countries are obtaining positive results, allowing the world to learn about their culture and history by using virtual reality techniques for the restoration of cultural property. Above all, the West has utilized the diversity of the CAVE system which could best express the artificial system among virtual reality systems. However, in Korea this technology remains in its early stages of development. Moreover, the field, digital restoration of cultural property, which will be discussed in this study, hasn't yet been explored. Accordingly, this study presents the way of digitally restoring cultural property based on the CAVE through the empirical research and suggests the significance and possibility of digitally restoring cultural properly in the CAVE system. For them, this study processes the digitally restoring of Pulguksa Temple and Sokkuram and refers to the limitation and the future study following the investigation of CAVE and the introduction of applicable examples in abroad.

Virtual reality is actively used in the medical field as a learning effectiveness that induces immersion, but research on the factors that induce learning immersion is insufficient. Therefore, this study extracted the usability and cognitive affordance evaluation elements of the interface through literature research and selected four types of virtual reality medical contents to conduct a Useability-Test for experts. Based on this, an interface design method according to virtual reality medical technology content was proposed. In summary, it can be seen that the information-providing interface affects immersion due to visibility, distance from the experience's gaze, color harmony, uniform visualization, feedback, reaction speed, and expected changes resulting from manipulation, and does not impair immersion. This study has limitations in generalization using limited content, so it is expected that continuous research will discuss the development of standardized guides in interface design and the precision of interface design research from a user perspective.

This paper is on a participatory spatial design methodology using Virtual Reality, which can be applied to the overall spatial design process. Participation in the current spatial design has several limitations: one-sided communication process, difficulty of understanding the given information and partial participation in the design process. Virtual Reality can be an ideal visualization tool for Geodesign and PPGIS(Public Participation GIS), which is presented as a highest step at the participation ladder. A participatory methodology is proposed to take advantage of Virtual Reality. In order to support participation through Virtual Reality in spatial design process, theories about the participation are compared to derive the new roles of Virtual Reality and the roles are formulated in the participatory spatial design methodology. By applying the methodology to the design process and implementing each stage through Virtual Reality, the design performance of each step can be verified in the methodology. As a result, design ideas can be effectively understood through Virtual Reality experiences. It is also confirmed that the interactions in Virtual Reality and participation are possible in the entire design process.

In this paper, we intend to demonstrate a new intuitive force-feedback device for advanced VR applications. Force feed-back for the device is tension based and is characterized by 7 degrees of freedom (DOF); 3 DOF for translation, 3 DOF for rotation, and 1 DOF for grasp). The SPIDAR-G (Space Interface Device for Artificial Reality with Grip) will allow users to interact with virtual objects naturally by manipulating two hemispherical grips located in the center of the device frame. We will show how to connect the strings between each vertex of grip and each extremity of the frame in order to achieve force feedback. In addition, methodologies will be discussed for calculating translation, orientation and grasp using the length of 8 strings connected to the motors and encoders on the frame. The SPIDAR-G exhibits smooth force feedback, minimized inertia, no backlash, scalability and safety. Such features are attributed to strategic string arrangement and control that results in stable haptic rendering. The design and control of the SPIDAR-G will be described in detail and the Space Graphic User Interface system based on the proposed SPIDAR-G system will be demonstrated. Experimental results validate the feasibility of the proposed device and reveal its application to virtual reality.

As the world game marcket has been recording weak growth, the development of new gane concept is required to attract the gamer's attention from those who were fed up with the previous game paradigm. Recently, the game which can recognize the player's motions and provide new interaction between the game and user is more popular than ever before. In the games with somesthesia based on Virtual Reality, the sense of the reality is considered the most important factor for drawing immersion from the gamers. In this work, a new type of 3-axis accelerometer based interactive game interface which can effectively recognize the gamer' motion is suggested. Furthermore, various experiments are carried out to verify the effectiveness of the proposed scheme.
