The development of stereoscopic display hardwares and 3D authoring softwares expands its application areas from particular virtual simulation applications to general movies, games, advertising applications. However, the binocular-based 3D stereoscopic images cause fatigue to viewers. Recent performed many research results about the binocular stereoscopy's depth perception and viewers' fatigue are derived from experimental users studies. In some results, watching and making guidelines for 3D stereoscopic imaging contents are introduced. The 3D stereoscopic-related contents have the contradictory aspects, which are audiences' pursuit of a tolerable minimum fatigue and producer's its of excessive depth changes for providing viewers' immersion. This paper provides user experiments and analysis data in aspects of 3D depth changes. For use of producers, a safety zone and translational velocity of 3D depth changes are introduced. Also, on the viewer side, we present the depth change adaptation time by using an EEG device.

This study deals with development of an evaluating tool for flow experience and presence to evaluate interactive digital contents. The tool is able to measure the grade of flow and presence by surveying with their factors which are known to affect flow experience and presence. One of reasons for reducing flow experience and presence in 3D digital contents is that the experience in the virtual world is different from user's prerequisite learning in the real life. The recent interactive contents using physical movement of users as an input is possible to provide unsafe situation to users due to the different experience. The suggested flow measurement tool is able to evaluate presence and flow experience of an interactive 3D contents as well as flow and presence factors are possible to use as a general guideline for all stages of producing interactive 3D digital contents.

As the demand for shared-type electric kickboards increases day by day, various companies in Korea are also providing shared-type electric kickboard rental services. With the rapid growth of related fields, users can easily rent shared electric kickboards in the vicinity, but management after use is not performed properly due to the absence of a designated rental station, and It is a situation that electric kickboards are being damaged. For this reason, citizens' perception of shared electric kickboards has changed negatively, and it is said that the service of shared electric bicycles is limited in some cities. Therefore, in this paper, we propose a user filtering system that extracts Black Consumers that can negatively affect the rental system through indiscriminate use. When this system is introduced, it is expected that safe electric kickboard use and management will be possible.

This study aimed to categorize consumers using super app functional characteristics to identify demographic differences, and analyze shopping orientations by consumer type. This data can be used by fashion and beauty companies for product planning and marketing strategies. To categorize super app consumers, data were analyzed with SPSS v.26.0 software using frequency, factor, reliability K-mean cluster, and distributed analyses, one-way-ANOVAs, and Scheffe verification. Cross-analysis was conducted to correlate super app consumer types with demographic characteristics. One-way-ANOVAs and Scheffe verification were used to analyze the differences in shopping preferences between super app consumer groups. As a result of our analyses, super app consumers were classified into four types: the ration type, the low-use type, the multifunction type, and the habit type. There were statistically significant differences between these types in age, occupation, marital status, average monthly household income, and shopping impact factors. Five super app user shopping orientations were identified: brand pursuit, pleasure pursuit, trend pursuit, risk perception, and economic orientation. The differences in the preferred orientation between super app consumer types were found to be statistically significant. The majority of respondents were multifunction type consumers. This group used the super app most frequently and effectively. They also demonstrated the highest scores for all five of the shopping orientations. The classification of consumer types in this study will allow the fashion and beauty industries to utilize super apps for more targeted product design and marketing.

Recently, types of mobile services are ever-growing with technological advances, such as CDMA 2000, 256 Color LCD, 16 channel sound chip set and easy internet access. However, manual system that is supposed to support users for finding features and functions doesn't help users most of the cases since users are moving. Therefore, mobile sonics needs new concept for manual system that can support users while they are in use In this research report, new concept for interactive manual system is suggested. Then a guideline for interactive manual system is developed as a result from three empirical studies. First, ten information visualization methods used for describing functions are positioned on user's perception map. Secondly, user behavior pattern of getting required information from written manual was analyzed. Finally, visual cue system was selected as one of options for developing interactive manual system and a guideline was developed based on these research results.

This article aims to improve the cultural program for the resident writers in libraries by identifying the current status of the resident writer support project, examining users' perceptions and preferences, and investigating librarians' perceptions of the program. The research methods included an investigation (survey) of the program operation status, user perception and preference surveys, and interviews with librarians about their perceptions of the program. Data were collected from libraries with the cultural program for resident writers between May and November 2021. Findings showed there were challenges in operating the library cultural program due to the lack of resident writers' quality, frequent changes in the program formats (online or offline), and library closures during the COVID-19 pandemic. For the program improvement, suggestions were made, including inviting good-quality resident writers and writers from other fields to the program, training resident writers, advertising the programs using online and offline media, training staff, and developing programs considering user ages and preferences and diversity in local communities.
