VR content manipulation equipment is not easy for individuals to access because it requires high prices. Especially, in the case of a system for tracking the motion of the user among the VR contents, a separate optical sensor device using an infrared camera is generally used. The disadvantage of the optical sensor equipment is that the measurable range is dependent on the measurement direction when tracking the rotation motion when using only a single device. In order to solve the above problems, this paper shows that the inertial sensor of the smartphone, which is generally owned by the public, can track the rotational motion of the user regardless of the measurement direction . The system using the LeapMotion is used as the reference system, and the system using the smart phone is defined as the evaluation system, and the usability of the evaluation system is verified by comparing the user satisfaction of the two systems.

At the same time, shipments of wearable devices such as smartwatches are growing every year, becoming more and more integrated into people's daily lives. This study presents a new possibility of reflecting the user's body signals measured through the combination of the two phenomena in the metaverse character. Various biometric information such as the user's heart rate and amount of exercise collected through the smartwatch are reflected on the character in the metaverse, allowing the user's physical condition to be reflected in the virtual world.

The objective of this study is to extract affecting factors on game satisfaction of a mobile game through the two mediated variables, self-fulfillment and flow. To apply mobile environment changed into the research model of a mobile game, we classify independent factors into three types such as system characteristics, cognitive characteristics, and individual characteristics. The previous studies for using mobile game have been based on intrinsic motivation, such as flow, as a mediated factor. However, the flow variable has some limitations in explaining user satisfaction aspects of mobile game, and the self-fulfillment variable is popularly used as an important mediated factor in the field of sports science. Because users of mobile game often attain their goals as sports event, we utilize self-fulfillment as well as flow as mediated variables. We developed a research model that includes independent factors, mediated variables of self-fulfillment and flow, and a dependent variable of game satisfaction. The data were collected from 438 users of mobile game and were used for analysis. Based on the survey results, we found the followings: (1) Immediate connectivity, enjoyment, relationship, early adopter tendency, and competitiveness affect self-fulfillment, and self-fulfillment affects the flow. (2) Enjoyment and competitiveness affect self-fulfillment, flow, and game satisfaction simultaneously.
