This article combines literature and empirical research based on space perception theory and the case study of mixed reality game "The Fragment." It is concluded that the mixed reality scene under space perception has a three-level visual definition. This definition carries out a corresponding level analysis of the scenes of the "The Fragment" game and draws up the constituent factors of the mixed reality game scene characteristics. Finally, through questionnaire data investigation and analysis, it is verified that the three factors of virtual reality coexistence, human-computer interaction, and local serviceability can better explain the characteristics of mixed reality game scenes. At the end of the study, it is concluded that the definition of three levels of visual hierarchy and the constituent factors of mixed reality game scenes can provide reference and help for other mixed-reality game designs and a brief description of future research plans.

Speed-run is a gameplay style in what the player tries to finish the game as quickly as possible. The purpose of this study is to observe and analyze the difference between a normal player and a speed runner in a speed run to better understand their interaction with the game and to extrapolate the applications of the analyzed frameworks to scenarios that extent normal gameplay. For this purpose, MDA (Mechanic, Dynamic, Aesthetics) and DPE (Experience, Design, Play) were used. As a result, the average player was found to focus on aesthetics or affects while the speed runner focused on mechanics and gameplay.

This study utilizes Roland Barthes' semiotic theory to explore how interface design elements of beauty camera apps, such as filters and stickers, icons and buttons, layout and structure, function as symbols of self-expression, and their impact on users' social identity and personal image. Through in-depth analysis of applications like BeautyPlus, Ulike, MeituPic, and Faceu, this research found that these apps emphasize usability, visual appeal, and social interactivity in their design. These elements not only enhance user experience and operational efficiency but also reflect popular cultural trends and aesthetic preferences. From Barthes' perspective, these interface elements have become "myths" with specific social meanings, which are naturalized in daily use and promote the widespread acceptance of particular aesthetic standards. These interface design elements are not just tools for self-expression; they are also powerful cultural symbols that shape modern social interactions and visual culture. This research offers a new perspective to understand the interactions between individuals and society in the digital age, emphasizing the role of technology, culture, and social interaction in shaping contemporary human behavior and social relationships.

Researches on the gesture recognition have become a very interesting topic in the computer vision area, Gesture recognition from visual images has a number of potential applicationssuch as HCI (Human Computer Interaction), VR(Virtual Reality), machine vision. To overcome thetechnical barriers in visual processing, conventional approaches have employed cumbersome devicessuch as datagloves or color marked gloves. In this research, we capture gesture images without usingexternal devices and generate a gesture trajectery composed of point-tokens. The trajectory Is spottedusing phase-based velocity constraints and recognized using the discrete left-right HMM. Inputvectors to the HMM are obtained by using the LBG clustering algorithm on a polar-coordinate spacewhere point-tokens on the Cartesian space .are converted. A gesture vocabulary is composed oftwenty-two dynamic hand gestures for editing drawing elements. In our experiment, one hundred dataper gesture are collected from twenty persons, Fifty data are used for training and another fifty datafor recognition experiment. The recognition result shows about 95% recognition rate and also thepossibility that these results can be applied to several potential systems operated by gestures. Thedeveloped system is running in real time for editing basic graphic primitives in the hardwareenvironments of a Pentium-pro (200 MHz), a Matrox Meteor graphic board and a CCD camera, anda Window95 and Visual C++ software environment.

Analogy in problem solving is similarity-based reasoning facilitated by verbal and visual operation. This similarity-based reasoning generally supports initial phase of idea search. Therefore, this study intends to infer the types of problem solving by tracing the analogy use of verbal and visual representation through a experimental research. According to the result of this research, the types of problem solving by analogy are classified into 'evolving', 'divergent', and 'poor conversion' type. Firstly, 'evolving type' is distinguished between 'combination type' associated different contents to develope a new design and 'transformation type' associated similar words and sketches to be continuously revised and developed. In these types usually structural analogy rather than surface analogy is used. Secondly, in 'divergent type' associated words or sketches are individually represented, and among them one design solution is selected. In this type usually surface analogy is used. Thirdly, in 'poor conversion type' interaction between verbal representation and visual representation does not go on smoothly, and the generation of idea is poor. In here surface analogy is mostly used. These findings could form the basis of skill development of idea generation and conversion in design education.

Repetitive stress injury at the wrist has been reported as a common injury among visual display terminal (VDT) users (i.e., computer users). Adjusting a VDT workstation (computer table and chair) to maintain a correct seated posture while operating a keyboard is perhaps the most frequently recommended preventive solution. This paper proposes an analytical design methodology based on ergonomic design principles for recommending appropriate VDT workstation settings and layout of individual computer accessories on the computer table. The proposed design methodology consists of two interrelated phases: (1) determination of VDT workstation settings, and (2) design of computer accessories layout. Based on the information about the VDT user, dominant task to be performed, typing skill, and degrees of physical and visual interactions between the user and computer accessories, adjustment and layout solutions are recommended to allow having a correct seated posture while minimizing both physical and visual movements. The results from an experiment show that when adjusting the workstation and locating the computer accessories according to the recommendations given by the proposed design methodology, the user's hand movements can be significantly reduced.

The purpose of this study was to investigate the differences of the visual image evaluation according to coloration of men's dress shirts and neckties, and perceiver's gender. Subjects were 336 males and females living in Seoul. Five dimensions of visual evaluation were derived by factor analysis: elegance/intelligence, sociability, potency/attractiveness, individuality, and manliness. White shirts were evaluated highly in elegance/intelligence, and blue shirts were shown the manliest. Women evaluated the blue shirts manlier than men did. Dark blue neckties were evaluated highly in elegance/intelligence and sociability, and red ties were perceived to be very distinctive. Black shirts and white shirts with silvery gray ties were perceived to be the most elegant and intelligent. Blue shirts with dark blue ties was evaluated highly in sociability and potency/attractiveness, and black shirts with yellow ties were evaluated the highest in individuality. The evaluations of elegance/intelligence, potency/attractiveness, and manliness had significant interaction effects between the color of shirts and neckties. White shirts and blue shirts with dark blue ties were perceived to be more elegant and intelligent, potent, attractive and manlier than with red ties.
