In order to design and develop a ubiquitous game, it is necessary to develop a natural and flexible interface between the real world and the virtual world, based on social and physical context awareness. We design user interface model and the tactile sensing system that performs virtual interaction and collection of the sensor data. It is sensitive so the collected data should be filtered, rearranged and analyzed. This information is quite different from stylus input, keyboard, button or mouse for interaction. We detect kicked 3D force position of a ball, moment of area, moment of inertia and modified ball shape using tactile sensing system and analyzed data. The results demonstrate that the proposed approach is desirable and robust as well as the results can be used realistic actions and reactions considering attack force and to make interesting environments for ubiquitous game.

The technology of 'Virtual Reality' has placed in advanced tools for human beings' joy and anger together with sorrow and pleasure in our generation. It has recently tried in a variety ways to use as an implication for treatment in the field of Cognitive Psychology. Especially, it widely approaches to human in terms of that a sense of reality in a virtual world through the five senses should reinterpret the meaning of cognition in the real world. Based on this paradigm shift, it allows for new treatment using the technology of virtual reality. A typical example is a field of Therapy in order to overcome panic disorder. It has advantages that in particular development of flexible interaction technologies in a virtual space can lead patients to experience psychological environments rather than physical one. the interaction technology provides environments in which users' five senses can be actively stimulated, it is very useful that information from the experiences in the virtual world allows people to learn through real experiences by renewing potential energies, advantages of Virtual Reality Therapy can be customized treatment by depending on symptoms in patients with panic disorder and are capable of differentiate application for the cure at each stage. It is to treat by leading patients to get accustomed to environments and situations in real world through care process with each symptom and stage. It is helpful that based on A Human-Sensibility Ergonomics, technologies like immersive virtual reality equipment, force-relative feedback and stereophonic sound, and like stimulating the sense of smell make people to induce experiences by stimulating human's five senses. There are many advantages of immersion in virtual world in that the phenomenon such as challenge, interaction, reality, illusion, and cooperation is expanded. As an application for therapy by growing such augmented reality, virtual space and sharing of data through the Internet and also inexpensive its availability have recently expanded the base. There are other benefits of Virtual Reality Therapy offering active interaction environments for cognitive experience which can provide appropriately adjusted environments for patients who are hard to overcome the real situation because of phobia. In addition to that it is safe and economical and patients' confidentiality is assured. Moreover, due to the principles of applying real-time navigation the Virtual Reality Therapy makes modification and supplementation easier and also it can reduce cybersickness because of the supply of Lenticular allowing people to see stereoscopy without eyeglasses, which makes sense of presence clearer. On top of that due to the development of interactive technologies, it is becoming close to sense of reality similar to real world by leading users to navigate by themselves and to operate objects in a virtual space. This paper will therefore examine, although it is of limited, characteristics of application of virtual reality technology based on A Human-Sensibility Ergonomics used for treatment for a disorder. this paper will analyse a range of its application and problems and it will suggest the future possibilities.

This study proposes an interface for providing mobile interaction suitable for mobile virtual reality (VR) and analyzes it through comparative experiments. The proposed interface is premised on not using additional equipment except for the mobile head-mounted display(HMD) in consideration of accessibility and usability. And the interface that controls the movement interaction using the user's gaze is designed in two phases. The key is to minimize the occurrence of negative factors such as VR sickness that can be caused by straight line movement in virtual reality. To this end, two phases are designed: an interface composed of forward/backward buttons to move the gaze toward the ground, and an interface composed of left and right buttons on the front in consideration of the gaze change in real walking motion. An application that can compare and analyze movement interactions through the proposed interface is produced, and a survey experiment is conducted to analyze the user's satisfaction with the interface experience and the negative impact on the movement process. It was confirmed that the proposed movement interaction reduced negative effects such as VR sickness along with a satisfactory interface experience for users.

This study investigates the interaction mechanisms and processes between cyber space and real space. In particular, we analyze the relationships between changes on the economic landscape of the Bookchon region and the information supply and demand for this area on the Internet Blogs. In order to obtain the behavioral data about how people get information for Bookchon area and the reaction afterward, we perform questionnaire survey. The results of analysis reveal that there are significant connection between real space and cyber space, Internet Blog in particular. Internet Blog is the major media obtaining information about Bookchon area for major portion of people. Most people visit Bookchon after searching informations about it via Internet Blog. In particular, young generations who possess better capability to treat social media. At the same time, female, student, and office workers show these attitudes very strongly. We introduce a conceptual model for the interaction processes between cyber space and real space based on the survey data analysis, and propose a simple theoretical model for the dynamics of the total number of visitors about specific place with the experience of cyber space visit.

The present investigation is concerned with the embodiment of virtual museum offering effective interaction with user. In real museum, we mainly get text-based information and we can't operate ancient relics as well. Nowadays there are various information service system about untouchable articles in the museum on the WEB, but each medium presents rather individual and unilateral information than useful and integrated one. This paper aims at the embodiment of virtual museum makes up for the weak points of the previous services. This cyberspace provides user with free viewpoint and navigation utilities and additional information for the corresponding 3D relics effectively.

This study evaluate user feedback such as physiological response and facial expression when subjects play a social decision making game with interactive virtual agent partners. In the social decision making game, subjects will invest some of money or credit in one of projects. Their partners (virtual agents) will also invest in one of the projects. They will interact with different kinds of virtual agents which behave reciprocated or unreciprocated behavior while expressing socially affective facial expression. The total money or credit which the subject earns is contingent on partner's choice. From this study, I observed that subject's appraisal of interaction with cooperative/uncooperative (or friendly/unfriendly) virtual agents in an investment game result in increased autonomic and somatic response, and that these responses were observed by physiological signal and facial expression in real time. For assessing user feedback, Photoplethysmography (PPG) sensor, Galvanic skin response (GSR) sensor while capturing front facial image of the subject from web camera were used. After all trials, subjects asked to answer to questions associated with evaluation how much these interaction with virtual agents affect to their appraisals.

The olfactory bio technology is largely based on its corresponding recognition technology and smell stimulus that acquires, analyzes, and processes volatile organic compounds present in chemical molecules, which are present in the breath or air evoked by an electronic nose artificially imitating the human biological nose. The olfactory bio technology is also based on a scent display technology that automatically diverges various digital flavors based on aesthetics, concentration, duration, and intensity information required to enhance the sensibility using a computer. Recently, attempts have been made to apply noninvasive screening of dementia by sensing, analyzing, encoding, and transmitting bio information obtained through an olfactory interface, both domestically and externally; further, the olfactory medical content technology has been applied to delay or reduce the onset of dementia. In this study, we will focus on early screening of dementia using olfactory biology information and dementia cognitive enhancer content that delays or reduces the onset of dementia.
