The purpose of the study is discovering the effects of virtual competitors on user in AR (Augment Reality) home training system. Specifically, the current research examined their effects on immersion, perceived competition, and leaning motivation. The paper tested three unexplored relationship. First, introducing virtual competitors in home training system will enhance user's immersion. Second, presenting virtual competitors in home training system will increase user's perceived competition. Third, virtual competitors in home training system will raise user's learning motivation. For empirical analysis, we developed home training system, which could check and give feedback automatically, based on user’s posture. Using this AR home training system, the study empirically shows how and why virtual competitors affect users. The results give implications not only on service design; but also on the idea that virtual other could affect user’s behavior.

Gift-giving is a special behavior where both givers and receivers are interactively involved. Thus, emotion and satisfaction for both sides are core factors in gift-giving research. Recently, gift-giving expands to a mobile venue by the growth of the industries in Korea. In accordance with this trend, some studies have been conducted regarding mobile gifts called `Gifticon`. However, most of them focused on the phenomenon based on the usage patterns and motives from the perspectives of givers. This study aimed (1) to figure out the emotional differences according to the action of giving Gifticons, and (2) to understand the effects of role and intimacy on the level of gift satisfaction. The results showed that, recipients felt higher levels of positive emotions such as excitement and thrill than givers whereas givers had different levels of gift-satisfaction depending on the intimacies to the receivers. This study is expected to suggest marketing strategies by providing psychological contemplations to a new form of gift-giving behavior, which is expanding toward a new mobile market. Further, it also suggests managerial implications by understanding the level of consumers` satisfaction from the role in Gifticon-giving situations and the intimacies between givers and recipients.

The purpose of this study was to analyze the effect of the shape and attached position of E-textile-based stretchable sensors on motion-sensing performance and to investigate the requirements for the optimal structure of clothes for sensing limb motions. An experimental garment was prepared with different sensor shapes, and attachment positions. A child subject, wearing the experimental garment, performed arm and leg bending and extension motions at 60°, 90° and 120° motion angles, at a rate of 60 deg/sec. The changes in voltage triggered by the stretching and contracting of the fabric-sensor were measured, and an acceleration sensor was utilized to verify that the experimental motions were correctly performed. Dummy arms and legs of a child were manufactured to perform an identical test, in order to compare the dummy results with the actual human body experiment results. The analysis showed that the reproducibility and reliability of the rectangular sensor, showing uniform and stable were higher than those of the boat-shaped sensor, in both the dummy and the human body experiments. The attachment position of the sensor was more reproducible and reliable when placed on 4 ㎝ below the elbow and knee joints in the dummy test, when placed in the joints of the elbow and knee, in children experiment. The appropriate shapes and attached positions of the sensor for sensing the motions were analyzed, and the results proved that motion-sensing of the human body is possible by utilizing flexible fabric-sensors integrated into clothes.

Current research aimed to demonstrate a way to enhance the aesthetic experience of the general public while appreciating contemporary art via online platform. Contemporary art is highly complicated and are avoided by the general public. Meanwhile, previous research confirmed that external information can lead to better aesthetic experience and appreciation of the artwork. Therefore, current research hypothesized that provision of explicit information may enhance the appreciation of contemporary artworks and aimed to demonstrate which phase of the cognitive process from Leder et al. (2004) profits from the aid of written information. Experimental environment reproduced online curating platform to reflect the current trend on exhibition. In experiment 1, subjects were presented with written information and reported how well they understood the artwork, and their willingness to visit the artwork in real life. Results revealed that written information had a positive effect on overall appreciation. Further analysis discovered a full mediation between information comprehension, artwork comprehension, and willingness to visit. In experiment 2, ARS questions and an interactive interface were added. Results indicated that information enhanced comprehension and intention to visit the artwork. Expertise, self-reference, and artistic quality which belong to later stages of Leder et al. (2004) model, acquired higher scores on information conditions. In sum, the current research illustrated clear effects of explicit information in inducing better aesthetic experience and cognitive process of contemporary artworks in online environment.

Individuals with high trait anxiety try to suppress their anger expression, thus there are limits in measuring their anger using subjective behavioral evaluation. In order to overcome this limitation, this study attempted to identify the difference in the autonomic nervous system responses induced by anger in individuals with high trait anxiety. Participants were divided into two groups, anxiety and control groups. Electrocardiogram (ECG), respiration (RESP), electrodermal activity (EDA), and skin temperature (SKT) were measured while participants were presented with an anger-inducing stimulus. Heart rate (HR), standard deviation of NN interval (SDNN), root mean square of successive difference (RMSSD), low frequency (LF), high frequency (HF), LF/HF ratio, respiration rate (RR), skin conductance level (SCL), and maximum skin temperature (maxSKT) were calculated before and after presenting the stimulus. Anxiety group reported greater anger by the anger-inducing stimulus compared to the control group. Anxiety group also showed significant increase in SDNN and LF, and decrease in HF, LF/HF ratio, and RR. These results suggest that the autonomic nervous system responses may be used as objective indicators of anger experiences in individuals with high trait anxiety.
