Garment design needs an iterative manipulation of 2D patterns to generate a final sloper. Traditionally there have been two kinds of design methodologies such as the flat pattern method and the pattern draping method. But today, it is possible to combine the advantages from the two methods due to the realistic cloth simulation techniques. We devised a new garment design system which starts from 3D initial drape simulation result and then modifies the garment by editing the 2D flat patterns synchronously. With this interactive methodology using real-time pattern deformation technique, the designer can freely change a pattern shape by watching its 3D outlook in real-time. Also the final garment data were given relative coordinates with respect to the human anthropometric feature points detected by an automatic body feature detection algorithm. Using the relative human body coordinate system, the final garments can be re-used to an arbitrary body data without repositioning in the drape simulation. A female shirt was used for an example and a 3D body scan data was used for an illustration of the feature point detection algorithm.

Extended Reality (XR), such as virtual and augmented reality, has huge potential for immersive data visualization and analysis. In XR, users can interact with data and other users realistically by navigating the shared virtual space, allowing for more intuitive data analysis. However, creating a visualization in XR also poses a challenge because complicated, low-level programming is required, which hinders broad adaptation in visual analytics. This paper proposes an interactive visualization authoring tool based on hand gesture for immersive data visualization-Gadget Arms. The proposed system provides a novel user interaction to create and place visualization in the 3D virtual world. This simple, but intuitive, user interaction enables user designs the entire visualization space in the XR without using a host computer and low-level programming. Our user study also confirmed that the proposed user interaction significantly improves the usability of the visualization authoring tool.

The purpose of this study is to closely analyze the case of blended-learning in order to provide a diverse and flexible learning environment while maintaining the nature of face-to-face classes, and to identify the learning environment that supports blended-learning in each class step and the educational experience of students. The experience and satisfaction of blended learning were investigated in various ways: course evaluation, LMS activity evaluation, and questionnaire before and after the class. As a result, the blended-learning is better than the traditional face-to-face classes, in providing real-time feedback, opportunities for various interactions, and textual conversations, anytime and anywhere. In addition, as a result of the preliminary survey, as a measure to solve the opinion that concentration was reduced due to problems such as networks and felt uncomfortable in the communication part, the theory and lectures of the design practice class were conducted non-face-to-face. The individual Q&A and feedback were conducted face-to-face and non-face-to-face. As a result of the follow-up survey, it was found that concentration and efficiency could be improved. This opens up possibilities for active use of the online environment in design practice classes.

This study investigates the antecedents and mechanisms influencing trust and behavioral intentions formation towards new AI chatbots, such as ChatGPT, as travel information searching services. Analyzing the roles of variables such as familiarity, novelty, personal innovativeness, information quality and perceived anthropomorphism, the research elucidates the impact of these factors on users' cognitive and affective trust, ultimately affecting their intention to adopt information and sustain the use of the AI chatbot. Results indicate that perceived familiarity and information quality positively influence both cognitive and affective trust, whereas perceived novelty contributes positively only to cognitive trust. Additionally, the personal innovativeness of new AI chatbot users was found to weaken the effect of familiarity on perceived trust, while the perceived level of anthropomorphism of the chatbot amplified the effects of novelty and familiarity on cognitive trust. These findings underscore the importance of considering factors such as familiarity, personal innovativeness, information quality and anthropomorphism in the design and implementation of AI chatbots, affecting trust and behavioral intention.

In this study, according to the Institut d'Estudis Catalan, it is noted that the traditional Catalan time telling system is essentially based on delineating time by the use of the 'quarts (=quarters)' of an hour. In this fasion, to tell the time 8:15, 8:30 and 8:45 they use '${\acute{E}}s$ un quart de nou.,' '$S{\acute{o}}n$ dos quarts de nou.,' and '$S{\acute{o}}n$ tres quarts de nou.,' but do not use constructions such as '$S{\acute{o}}n$ les vuit i quinze.,' '$S{\acute{o}}n$ les vuit i trenta/mitja.,' '$S{\acute{o}}n$ les vuit i quaranta-cinc.,' because these expressions are considered to be as dialectal variants or international notation-based variants. Moreover, the traditional Catalan time telling system does not use cardinal numbers, except in the case of 'cinc (five)' and 'deu (ten).' These linguistic phenomenon cause the invention of a unique Catalan digital watch, and has noted special designs for the creation of a Catalan analogue watch. For this reason, the quarter system in colloquial Catalan provokes an enormous interpretative ambiguity in daily routine expressions with 'quarts' like '$S{\acute{o}}n$ quarts of nou.' or 'entre dos i tres quarts' whose meaning is not delineated between sixteen and forty-four minutes. We will argue that the traditional Catalan time telling expressions do not have the use of the subtractive system, and the fraction word 'quart' lacks a specific meaning of fifteen minutes because the Catalan word 'quart' is etymologically related to the classical public bell system, not definitively to the traditional clock system.
