The application of Augmented Reality(AR) technology is visible in medical procedures, education, marketing, and journalism. By experimenting, this study examines how the evaluation of the three elements of augmented reality news contents(visual image, storytelling, interactivity) affects immersion and information acquisition. Specifically, a 2 (video technology: AR vs. general) × 2 (news type: disaster vs. sports) between-subject design was examined. Results showed that the evaluation of all three elements was higher when viewing AR news than when viewing general news. The level of immersion was higher when viewing AR news, and the evaluation of storytelling and interactivity had positive effect on the level of immersion regardless of the news types. However, the evaluation of visual images did not affect the level of immersion. Information acquisition was higher after viewing AR news, yet the effect of the evaluation of the three elements on information acquisition had not been found. Implication and discussion of the study were added in the end.

This study aimed to analyze consumers' acceptance of sports applications and smart sportswear to better design technology-enhanced walking exercise wear for the Baby Boomer generation based on their cohort characteristics. A questionnaire with items related to acceptance of existing smart sportswear design, functionality, and usability as well as existing sports application design, functionality, and usability was sent to consumers aged 50-65. Of 163 questionnaires distributed, 150 were used for analysis. The results showed that middle-aged consumers were aware of smart sportswear's functional stability, but were concerned about care, durability, and convenience. Middle-aged consumers were also aware of sports applications as educational functions for obtaining new information. Additionally, they found sports applications to have lower perceived convenience and accessibility relative to the young generation, highlighting the need for simple instructions and explanations for sports application planning. Based on these results, we propose "Everyday design for general sportswear," "Functions based on consumer's preference," "Enhanced design for durability and management convenience" for designing and planning walking exercise wear for middle-aged consumers, and "Convenient application organization" and "Educational exercise contents" for application planning for walking exercises.

The purpose of this study was to investigate the experiences of male college students through sport toto gambling and to provide basic data on the prevention program for male college gambling addicts. Participants in the study were eight male college students who were interviewed in depth and analyzed according to Colaizzi's phenomenological study method. As a result of this study, four categories of experiences were derived as follows: Like the wind that rushes to the sea, Tears of remorse, A locked down life and On a dream day. Research shows that sports toto is easy to access and has a lot of interesting factors, however it has been found out that male college students have a great risk of falling into addiction aiming to win at once like ordinary gamblers. Therefore, this study suggests that gambling preventive education and counseling are necessary for male college students who like sports.

– In the paper, to handle the problem of traditional bag-of-features model ignoring the spatial relationship of local features in human action recognition, we proposed a Multiscale Spatial Position Coding under Locality Constraint method. Specifically, to describe this spatial relationship, we proposed a mixed feature combining motion feature and multi-spatial-scale configuration. To utilize temporal information between features, sub spatial-temporal-volumes are built. Next, the pooled features of sub-STVs are obtained via max-pooling method. In classification stage, the Locality-Constrained Group Sparse Representation is adopted to utilize the intrinsic group information of the sub-STV features. The experimental results on the KTH, Weizmann, and UCF sports datasets show that our action recognition system outperforms the classical local ST feature-based recognition systems published recently.

Wrestling is one of the popular events for modern sports. It is difficult to quantitatively describe a wrestling game between athletes. And deep learning can help wrestling training by human recognition techniques. Based on the characteristics of latest wrestling competition rules and human recognition technologies, a set of wrestling competition video analysis and retrieval system is proposed. This system uses a combination of literature method, observation method, interview method and mathematical statistics to conduct statistics, analysis, research and discussion on the application of technology. Combined the system application in targeted movement technology. A deep learning-based facial recognition psychological feature analysis method for the training and competition of classical wrestling after the implementation of the new rules is proposed. The experimental results of this paper showed that the proportion of natural emotions of male and female wrestlers was about 50%, indicating that the wrestler's mentality was relatively stable before the intense physical confrontation, and the test of the system also proved the stability of the system.

In this paper, capture motion and visual information from a virtual reality luge simulator to analyze muscular activity in the lower limbs. The Luge Simulator consists of a motion platform with a pneumatic module for weight distribution. We recruited luge athletes and healthy subjects and made real-time surface EMG measurements to estimate the muscular activity in the lower limbs according to the motion protocol of a simulator, and a test was conducted for each subject. The results indicated that the rectus femoris had the highest muscular activity according to the level of the slope and velocity of the luge. The soleus muscle showed a high level of activity during a turn in the luge according to the direction. We found that the development of a virtual reality sports simulator based on physical reaction results could bring positive effects to optimize reality and human cenesthesia.
