Among the formative elements, color and form are the most critical elements that can capture a person's perspective. Companies are concentrating on developing visual perception-oriented products by accommodating the diverse needs of consumers, where the emotional factor plays as an important design consideration. Accordingly, the visual perception reaction of consumers was analyzed through a questionnaire focusing on color and form. The result finds that, when Ernst Gombrich (1909-2001) perceives objects in questionnaires related to personal preferences for color and form, humans do not rely solely on the eyes, but describes with the knowledge diagram through that knowledge. In doing so, the knowledge that we already know plays a part to describe the object. In addition, colors and forms are recognized by combining the social and cultural information experiences of the perceiver with the learned knowledge. In the future studies that define the interrelationships of the formative elements should be continued through the analysis of more complex and clear visual perception characteristics of the formative elements.

The purpose of this study was to verify the effectiveness of the computerized cognitive rehabilitation program in which areas and to suggest effective ways to utilize the program in the future, being conducted for 20 college students. We lasted this study from May 3 to 23, 2021. As a result of analyzing the groups using the Computer-based Cognitive Rehabilitation Program (CoTras), in terms of the difference in accuracy for the case of visual perception group B was statistically significantly improved than group C(p<0.05). In the case of attention, memory, and orientation, there was no significant difference between groups(p>0.05). In the case of reaction time difference, there was no significant difference between groups in visual perception, concentration, memory, and orientation(p>0.05). And in order to improve attention and visual perception, it is recommended to conduct the program three times with a duration of 20 minutes, and in order to improve orientation and memory, it can be said that it is helpful to conduct one experiment for at least 30 minutes rather than conducting short and frequent experiments. Through this study, we found that it is effective to apply different times according to each area to improve cognitive function. In other words, depending on the purpose of which cognitive function is to be improved, the duration of the program should be applied differently.

The purpose of this study is to examine whether the visual materials presented in the science textbooks coincide with those visual materials that are preferred the most by students. After analyzing the visual materials presented in the unit "Molecular Motion and Change of State" of science textbooks for the first grade of middle school, questionnaires by teaching-learning process are made. Thereafter, students are requested to select those types of visual materials that were preferred by them by process and describe their reasons for the selection. According to the results of the survey of students' perception, students at the high science achievement level prefer those visual materials that were presented conceptually and implicatively, while students at the low science achievement level prefer concrete and detailed visual materials. Except for the learning motivation process, the proportion of non-preferred visual materials is higher in the remaining processes and those visual materials that were presented in the science textbooks are much different from those visual materials that were preferred by students.

본 연구는 유명 인기 캐릭터를 대상으로 한 시선추적실험을 통해 피험자의 시지각 집중도를 분석하여, 캐릭터에서 어떤 부분을 부각시키는 것이 소비자들의 관심과 호기심을 유도하는데 효과적인가를 알아보았다. 연구결과, 캐릭터의 몸보다 얼굴에 더욱 주목하였으며, 그 외 바지, 티, 신발, 수염과 같은 보조요소에도 다소 주목하는 것을 확인하였다. 이러한 결과는 캐릭터에 대한 피험자들의 시선이 자주 그리고 오래 머무는 요소가 명확하게 다름을 의미한다. 그러므로 디자이너들은 캐릭터 구성요소별 시지각 집중도의 차이를 캐릭터에 대한 사용자의 관심과 감정이입, 몰입과 같은 감성적 만족감을 느낄 수 있는 차별화 요소로 인지하고 캐릭터 디자인을 개발할 때 적극적으로 반영해야 할 것이다. 또한 각각의 보조요소의 시지각 집중도에 차이가 있었는데, 그 영향요인 또한 개인의 특성에 기인한 것인지, 아니면 또 다른 영향요인이 발현된 것인지에 대한 세심한 연구가 이루어진다면, 캐릭터 디자인의 보다 폭넓은 연구가 될 것이다.

VR browser is one of the most popular applications for VR(Virtual Reality) environment. However, because most of the web contents are not designed considering the VR environment, scrolling the web pages in the VR browser causes much visual discomfort. We found it's because the angular velocity of the eye movement during scrolling increased because the viewing distance got closer compared with legacy devices. So we have developed a technology that regulates the scrolling to reduce the visual discomfort in the VR browser, in reference of the visual perception characteristics of the human visual system.

Auditory and visual stimuli presented in the peripheral visual field were perceived as spatially coincident when the auditory stimulus was presented five to seven degrees outwards from the direction of the visual stimulus. Furthermore, judgments of the perceived distance between auditory and visual stimuli presented in the periphery did not increase when an auditory stimulus was presented in the peripheral side of the visual stimulus. As to the origin of this phenomenon, there would seem to be two possibilities. One is that the participants could not perceptually distinguish the distance on the peripheral side because of the limitation of accuracy perception. The other is that the participants could distinguish the distances, but could not evaluate them because of the insufficient experimental setup of auditory stimuli. In order to confirm which of these two alternative explanations is valid, we conducted an experiment similar to that of our previous study using a sufficient number of loudspeakers for the presentation of auditory stimuli. Results revealed that judgments of perceived distance increased on the peripheral side. This indicates that we can perceive discrimination between audio and visual stimuli on the peripheral side.

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.
