Purpose: The purpose of this study is to investigate whether types of sensory-stimuli cues in terms of visual, auditory, and visuoauditory cues can be affected to motor sequential learning in healthy adults, using serial reaction time task. Methods: Twenty four healthy subjects participated in this study, who were randomly allocated into three groups, in terms of visual-stimuli (VS) group, auditory-stimuli (AS) group, and visuoauditory-stimuli (VAS) group. In SRT task, eight Arabic numbers were adopted as presentational stimulus, which were composed of three different types of presentational modules, in terms of visual, auditory, and visuoauditory stimuli. On an experiment, all subjects performed total 3 sessions relevant to each stimulus module with a pause of 10 minutes for training and pre-/post-tests. At the pre- and post-tests, reaction time and accuracy were calculated. Results: In reaction time, significant differences were founded in terms of between-subjects, within-subjects, and interaction effect for group ${\times}$ repeated factor. In accuracy, no significant differences were observed in between-group and interaction effect for groups ${\times}$ repeated factor. However, a significant main effect of within-subjects was observed. In addition, a significant difference was showed in comparison of differences of changes between the pre- and post-test only in the reaction time among three groups. Conclusion: This study suggest that short-term sequential motor training on one day induced behavioral modification, such as speed and accuracy of motor response. In addition, we found that motor training using visual-stimuli cue showed better effect of motor skill acquisition, compared to auditory and visuoauditory-stimuli cues.

The visual design elements of packaging play an vital role in attracting consumers' attention, forming their sense of pleasure and sensory expectations, as well as having an important impact on the actual product experience. This study aims to explore whether the colors and textures in the packaging design elements of canned beer will affect consumers' senses, judgments and taste perception of canned beer. Participants in Survey I (N=193) evaluated their expectations for beer freshness, softness, bitterness and alcohol content by observing the packaging of canned beer, then recorded whether they could get the expected experience when tasting beer, and evaluated their preference and purchase intention. In the Survey II, 4 kind of colors and 2 types of texture shapes were applied, and all participants were provided with the same beer for multivariate cross contract analysis to evaluate the specific impact of color and texture of packaging design elements on consumers' taste and the interaction between sensory judgment and taste perception.The results showed that both colors and textures had a significant affect on the sensory expectation (pre-tasting score) of canned beer, but their effects on the sensory score after tasting (actual perception)were inobvious. The analysis of the influence of the interaction between color, texture and shape on taste perception shows that when the expected packaging appearance perception is similar to the actual drinking perception (i.e., straight line and B/G or arc line and Y/R), it is more likely to obtain consumers' favor and higher purchase intention evaluation than the inconsistent canned beer packaging (i.e., straight line and Y/R and arc line and B/G). This paper discusses the influence of these results on the packaging design of canned beer and the possibility of improving the brand efficiency by meeting the visual elements of packaging design expected by consumers.

본 논문에서는 방송국 그린 스튜디오에 서 있는 연기자와 CG로 표현되는 스페셜 이펙트(물, 불, 연기 등)와의 상호작용을 제공하는 시스템을 제안한다. 기존의 가상 스튜디오는 주로 CG 배경과 연기자 촬영 영상을 정합하는 방법에 초점을 맞추고 있다. 기존의 연구와 달리 본 논문에서는 실제 연기자와 상호작용하는 비주얼 이펙트를 시뮬레이션하는데 집중함으로써 TV 화면에서 새로운 영역을 표현하고자 한다. 연기자 동작에 비주얼 이펙트를 연동하기 위하여 깊이 카메라를 이용하여 연기자 동작을 추출한다. 이를 3차원 벡터 필드로 변환하고 Navier Stokes 방정식의 외력으로 적용하여 물, 불, 연기의 유체를 시뮬레이션한다. 특히, 물의 상호작용을 사실적으로 표현하기 위하여 물에 연동되는 스플레쉬의 상호작용도 함께 시뮬레이션하여 물이 등장하는 비주얼 이펙트의 사실감을 극대화시켰다. TV의 실시간 녹화를 지원하기 위하여 GPU 프로그래밍을 도입하여 VFX의 실시간 상호작용을 지원하는 기능도 추가하였다. 제안된 방법의 유용성은 물, 불, 연기, 바다 속 물고기 떼 등의 VFX 시뮬레이션과 연기자와의 상호작용 실험을 통하여 확인할 수 있었다.

가상 및 증강현실과 같은 확장현실(XR: Extended Reality)은 몰입형 데이터 시각화 및 분석을 위한 거대한 잠재력을 가지고 있다. 확장현실에서 사용자는 3차원 가상 공간을 활용하여 데이터 및 여러 사용자와 사실적으로 상호 작용할 수 있으므로 보다 직관적인 데이터 분석이 가능하다. 그러나 확장현실의 장점을 제대로 활용하기 위한 시각화를 생성하는 것은 복잡한 프로그래밍이 필요하기 때문에 상당히 어려운 일이다. 본 논문에서는 손 제스처만으로 XR을 위한 시각화 전 과정을 수행하고, 모든 3차원 공간을 활용할 수 있는 가젯암(Gadget Arms) 시스템을 제안한다. 이 시스템에서 분석가는 데스크탑 기반 환경이나 복잡한 프로그래밍을 사용할 필요 없이 XR 기기를 착용한 상태에서 직관적으로 전체 시각화 공간을 디자인할 수 있으며, 가상의 손을 임의의 3차원 공간에 자유자재로 위치시킬 수 있는 인터랙션을 통해 거대한 3차원 공간을 효과적으로 활용할 수 있다. 우리는 사용자 연구를 통해 제안된 시스템이 시각화 제작과 공간 활용의 사용성을 크게 향상시시키는 것을 확인하였다.

The purpose of this study was to find out differences of visual evaluation according to perceiver's personality(introvert-extrovert) and clothing styles. Subjects were 120 women in age from 18 to 31 years in Seoul. The stimuli of 7 clothing styles were used for visual evaluation. Three dimensions of visual evaluation were derived by falters analysis: elegance, activity individuality, and fashionability. The pants suit was estimated low in activity individuality and fashionability, but the hip-hop style high in activity individuality. The skirt suit was rated high in elegance, but the 8th length pants low in elegance. Personality had significant influences on the evaluation of activity individuality. Extrovert women perceived all stimuli to be more active and individual than introvert. Fashionability factor had an interaction effect by personality and clothing expenses. The introvert women in low clothing expenses group evaluated the stimuli to be more fashionable than the introvert in high clothing expenses group. There were significant differences in preference of all clothing styles according to personality. Extrovert women liked 8th length pants more than introvert. The introvert women in low clothing expenses group liked the skirt suit less than the extrovert.

Numerous scholars have explored the modeling, control, and optimization of energy systems in buildings, offering new insights about technology and environments that can advance industry innovation. Eye trackers deliver objective eye-gaze data about visual and attentional processes. Due to its flexibility, accuracy, and efficiency in research, eye tracking has a control scheme that makes measuring rapid eye movement in three-dimensional space possible (e.g., virtual reality, augmented reality). Because eye movement is an effective modality for digital interaction with a virtual environment, tracking how users scan a visual field and fix on various digital objects can help designers optimize building environments and materials. Although several scholars have conducted Virtual Reality studies in three-dimensional space, scholars have not agreed on a consistent way to analyze eye tracking data. We conducted eye tracking experiments using objects in three-dimensional space to find an objective way to process quantitative visual data. By applying a 12 × 12 grid framework for eye tracking analysis, we investigated how people gazed at objects in a virtual space wearing a headmounted display. The findings provide an empirical base for a standardized protocol for analyzing eye tracking data in the context of virtual environments.
