With the fast improvement of software and hardware technology of Virtual Reality, VR(Virtual Reality) film get attention for the new possibility of future film. Already, the production of virtual reality film festivals and Hollywood films is highly active, but it is still poorly related to virtual reality films in Korea. Due to this, this research analyze VR film with Realism films and Post-modernism films in four aspects that are film's frame(Mise-en-$Sc{\grave{e}}ne$), shot(montage), vew point and interactivity to deduct characteristics of VR film. Moreover, we also deduct an esthetical characteristic of VR films beyond the Realism films and Post-modern Films through analysing various VR films. This can be said as 'Digital Realism' that is come from the viewers' positive interaction and realization of Realism through Virtual Reality technology. There will be a successful development of VR film based on this research that analyse suitable directing method for Virtual Reality environment. At last, this research focused on characteristics of digital realism aspect for HMD based first person view VR animation .

The film has always reflected the culture of the era based on reality and imagination. The visual effect in the film has mainly played a role of expressing the reality more realistically or recognizing the virtual as reality. This study examines the meaning and the effect of fantasy realism through Oasis of Lee Chang-dong. Fantastic realism has separated the reality from the imaginary space by using a dual meaning tool that affects the time and space in the film and reflects the human desire and desire to see. It was also reproduced in the real world through the medium of pigeons. In addition, it separates visualized space from non-visualized space in film narrative structure, separation of real and unreal space, segregation of consciousness and unconscious space, and separation of reality and reality space into power structure. With the development of technology, the image of the yellow image comes closer to us like reality, which will express the space of unconsciousness that we could not think of.

The most fundamental difference between general three dimensional computer graphics technology and virtual reality technology lies in the degree of realism as we feel, and thus the virtual reality method heavily relies on such tolls as data gloves, 3D auditory system to enhance human perception and recognition. Although these tolls are valid for such purpose, more essential ingredient. This paper provides further realism by modeling active interactions between the objects inside scenes. For this purpose, this paper proposes and implements a field model where the virtual reality space is treated as a physical field defined on the characteristic radius of stimulus and sense corresponding to the individual object. In the field model, the rule of cause and effect as an essential feature of the realism can be interpreted simply as an energy exchange between objects and consequently, variation on the radius information together with behavioral logic alone can build the virtual environment where each object can react to other objects actively and controllably.

Content featuring next-generation weapons is continuously appearing in games and virtual reality. In the context of story development, the traces of a target's bullet marks are observed differently according to the unique characteristics of the rifle and bullet. Additionally, there is an example of using forensic ballistics to investigate crime by examining the traces of bullets. Understanding the relationship between the ballistic coefficient and cavity by ballistics is crucial during this process. This paper proposes a physics-based cavity simulation using the modified Bresenham's line algorithm, which can enhance realism in games and virtual reality. This simulation accurately models the trajectory of bullets and cavity formation upon impact, creating a more realistic representation of how bullets interact with materials. Overall, physics-based simulations can greatly enhance the realism and immersion of games and virtual reality experiences and can have applications in forensic investigations.

This paper suggests a collision techniques for a higher reality in augmented reality by processing collision between a real object obtained through video frame input and a marker-based virtual object or a virtual object from Opengl. Augmented reality system is providing the visual information containing a virtual object added to the real environment and interactive interface between objects and between user and objects becomes a more concerning interest. But the collision problem is essential to the interactive interface and has to be solved first. Therefore, the proposed system suggests a solution for it to increase the realism and the immersion by validating the collision among a marker-based object, a virtual object from Opengl, and a real object obtained through web camera, that is, video frame.

In this paper, we propose a system to walk around the world with virtual reality technology. Although the virtual reality users are interested in the virtual travel contents, the conventional virtual travel contents have limited space for experiencing and lack of interactivity. In order to solve the problem of lack of realism and limited space, which is a disadvantage of existing contents, this system created a virtual space using Google Street View image. Users can have realistic experience with real street images, and travel a vast area of the world provided by Google Street View image. Also, a virtual reality headset and a treadmill equipment are used so that the user can actually walk in the virtual space, which maxmizes user interactivity and immersion. We expect this system contributes to the leisure activities of virtual reality users by allowing natural walking trip from famous tourist spots to even mountain roads and alleys.

Museums are converging with digital technology to convey information to viewers in various ways. Augmented reality technology enhances virtual objects seamlessly in the real world, and provides a high sense of immersion and realism because it can use various senses of users in combination with information providing role of exhibits. However, the location-based augmented reality may cause the inaccurate registration of the virtual object with the real world due to the error of the GPS information, and the vision-based augmented reality can be enhanced at the position where the marker is placed. To solve this problem, we implemented the exhibition contents that interact with the real world by using the developed project tango. The exhibited contents were based on Lenovo Phab 2 Pro and Project Tango SDK in Unity 3D. Visitors were able to improve immersion and realism in exhibition contents, and it would be able to combine with various exhibition fields such as shopping malls as well as museums.

There are several kind of surface deformation display methods using the fuzzy model. In this paper, we describe three fuzzy display methods for a surface deformation and perform a comparative analysis between the modified fuzzy display method and some conventional fuzzy display methods. In each method, the analysis will be performed through computer simulation in order to show the performance of each algorithm. The results show that the modified method have improved the realism and can be used better than the conventional methods in practical applications.

Due to COVID-19, the face-to-face on-site exhibitions were not held. With this opportunity, technologies such as virtual reality/augmented reality are increasing attention, and these technologies are being used in many fields. In this study, we made a virtual exhibition content which was produced using virtual reality technology. Our virtual exhibition was held in parallel with the on-site exhibition that included the same contents. Also this exhibition provided an opportunity to realistic experience using the head mounted display. In order to provide a high sense of presence, we created an open virtual space and used realistic 3D objects and textures. Although it is a virtual exhibition, the audience can experience a sense of realism like an on-site exhibition. After the exhibition was over, a survey was conducted on the audience who participated in both the on-site exhibition and virtual exhibition to analyze their responses. As a result of the survey, the similarity and immersion of the virtual exhibition were highly evaluated.

In this paper, we propose the matching model between virtual reality and the real-world for peoples with limited mobility. The proposed matching model is consist of four parts: wearable input device-based PC control, hand-motion pattern recognition, application software, and matching between virtual reality and the real-world. To recognition mouse functions and hand-motion patterns from six-axis coordinate of wearable input device, RF communication is used. In addition, to easily control the real-world, virtual reality has been implemented with realism of the real-world. Some experiments are conducted so as to verify the proposed model, and as a result, hand-motion recognition as well as virtual reality control are well performed.
