  • This study was designed to investigate how the size perception of letters is influenced by its relation to the ground, visual angle, physical size, letter space and cognitive direction. As a stimulus, a word in the Numeral and Hangul respectively were used in Experiments I and II. Fifty four different configurations consisting of two grounds, three visual angles and nine physical sizes were used as test patterns in Experiment I, and one hundred and eight different configurations consisting of two ground, three directions, two letter spaces and nine physical sizes were used in Experiment II. Subjects were asked to make magnitude estimates for perceived size of test patterns in both Experiments I and II. The results imply that the ground and visual angle affected the perceived size of the Numeral as a focal figure. We found that in Experiment I, the perceived size of the focal letter was clearly underestimated when the rate of physical size was larger than the real size which was a hundred(as the size of standard stimulus), and it was overestimated when the rate of physical size was smaller than a hundred. It was found that the effect of Delboeuf illusion influenced the perceived size of letter. The result of Experiment II shows that the ground, physical size, letter space and the cognitive direction affected the perceived size of Hangul as a focal figure. These findings suggest that size illusion of letters is caused by the size relationship (contrast or assimilation) between a letter perceived as figure and its ground.

  • Interesting education which utilizes cyber visual and audio multimedia effects, we regard it as a very effective education but those programs are not prepared yet. So, the purpose of this research is to provide a new direction for cyber fashion education with the use of avatars as the multimedia factor to increase student's interest and understanding. First, we investigated the present situation of fashion cyber education and the present avatar usage situation online, and also we searched literature and the internet to investigate the general theory of design. Second, we used Adobe photoshop 7.0 to make avatars, then, we used Macromedia Flash MX to design the avatar on our web site, and to make it look more realistic. According to the research results, cyber fashion education is usually used as marketing in certain areas, and for middle school, and high school students it is mainly used as text and lecture videos. When searching for fashion sites that use avatars, we found that most fashion shopping malls use them. Because avatars can give visual effects and also increase interest and fun, they can increase concentration and understanding and can be effective in fashion cyber education.

  • Anamorphosis is highly favored in modern days as the atmosphere of pursuing unusual manners is growing while transformation and distortion of images are freely available. This research is to understand the affect of these distorted images on space designs and the close connection between anamorphosis and visual perceptions, and to identify the new perceptual phenomenon created through it, and the methods of expressing those. Four expressional methods were defined through the process of studying Anamorphosis based on its definition by Niceron, examining artworks such as paintings and photographs, and case-studying example spaces of visual perception experiments. Expressing anamorphosis through visual perceptions are broadly categorized to directional, dimensional, flatness, and optical. The analysis of 10 case projects suggests that the experimental spaces offer joys of finding and interpreting metaphorical forms and meanings caused by the four characteristic categories above. Also, they artificially show the boundaries between reality and virtual spaces in 2-dimensional or 3-dimensional spaces, and form hyper-boundaries, new experience, and an internal mechanism that is vague and chaotic. Therefore, this research concludes that anamorphosis which is a distorted perspective, is not only a simple measure to overcome perspectival errors, but is an existence suitable to the current era, that will extend its potential and value in spatial design.

  • This paper focuses on the spatial changes that create a three-dimensional or deep feeling on the surface of a scarf centering on the cube shape. Through this, consumers with various tastes were able to satisfy their image presentation. The cube form has simplicity and order and is likely to be used as a formative object. The cube shapes can be expressed in various forms through visual and perceptual spatial changes by presenting various shape changes based on the viewpoint of the two-dimensional silk surface, that is, by changing the eyes' position and orientation. Various visual theorists' discussions about cube-shaped visual changes were discussed. In addition, the three-dimensional spatial illusion caused by the shape and color of Victor Bazaarelli's cube was examined. The cube shape was printed silk surfaces to give a three-dimensional sense of space on a two-dimensional scarf design using the size change, the difference in the length of the line, and the color change. As such, the cube shape has infinite possibilities as a method that can express three-dimensional depth and space on the flat surface of a scarf. Therefore, it is hoped that this study will be applied to various aspects as the basic data for the scarf design that expresses the spatial changes in the form of cubes.

  • With a long crotch length and much ease in the hip area, baggy pants are visually expressed in a variety of designs when compared with regular pants. The purpose of this study is to define the image differences of various baggy pants designs according to hip circumference and crotch length ease. To that end, this study deduced the visual image variable of experimental baggy pants and analyzed visual images according to changes in hip circumference and crotch length. Nine baggy pants with different levels of hip circumference and crotch length ease were produced as experimental pants. The image of each pair of experimental baggy pants was evaluated based on pictures taken of the pants worn by a woman in her 20s with a standard body figure. The image assessment team was composed of 105 clothing majors. The research results are as follows. Four visual image factors of experimental baggy pants were extracted: whole body compensation, lower body compensation, hip compensation, and waist compensation. Among the 4 factors, the whole body compensation factor was shown as the most representative factor. The body compensation image was higher with less hip circumference ease in the experimental baggy pants, and more hip circumference ease created the optical illusion of a larger body figure, presenting a significant difference between waist circumference and hip circumference. The lower body compensation factor, hip compensation factor, and waist compensation factor all showed a significant influence on changes in hip circumference ease. This result shows that changes in hip circumference ease exerted more influence on the body compensation image than did changes in crotch length ease. The results of this study provide basic data for predicting visual images according to differences in the level of ease in baggy pants, helping people select clothing suitable to their preferences and body shapes.

  • This study aimed to find the components of visual image by researching main image-related adjectives applied to high-waist skirts. In addition, it compared and analyzed the differences and mutual influences of visual images according to variations in the waistline and skirt length of high-waist skirts. The researchers made nine high-waist skirts-combinations of three different levels of waistlines and skirt lengths. The test involved 121 people who hold degrees in the field of Clothing and Textiles. The panels tested actual images of all models wearing the high-waist skirts shown on a computer screen. The results of the study are as follows.: Four factors affected the visual image as waist-height and skirt-length changed: attractiveness, upper-body compensation, length compensation, and hips compensation. Among these factors, attractiveness was estimated as the most important factor. The torso and the hip were highlighted as the waistline increased from 3cm to 11cm, due to the optical illusion of a tighter skirt wrapping the bust, waist, and hips. As the waistline increased, the stature and leg length increased, possibly revising the overall appearance. For the skirt length, a length measuring 20cm above the knees, proved to be most attractive. This resulted in elongated height and leg length, and a slimmer overall look.

  • Animation fascinates people. Fascination can be defined as a state in which one's attention is irresistibly taken and remains that way even though he/she gains nothing from the object. The power of fascination of animation comes from the fact that the illusion in animation looks as convincing as the reality. In order to successfully fascinate spectators, animation should attract their eyes with visual sensation (confusion), and then quickly have them immersed into the narrative, the inner logic that rationalizes the confusion while the attraction lasts. Animation fascinates us with both visual sensation and narrative, and this fascination is the reason why we keep making animation in spite of the extra efforts it requires. Our fascination to animation is a eulogy to the fantasy so convincing that makes our perception discords with our reason.

  • The surrealism for the revelation of the unconscious realms shares the inner world of mentality with modern fashion display for the visual expression of sensation each other. The analysis of the influence which automatism technique of surrealism exerts on fashion display showed as follows : 1) The automatism technique elevated the dramatic effect of the sales room by scraping the perspective, or the principle of visual arts. 2) It maximized the effect of subject of the display by coinciding surrealism with realism. 3) The technique which distorts the things heralded the strong message to customers by letting them keep away from the fixed idea. 4) Humorous expression of display brought about the effect of sales stimulation by giving astonishment, shock and exaggeration. 5) Expression of surrealism and realism caused customers to feel shock, illusion, fantasy. 6) The automatism technique expressed the high-tech image, and free expression by revealing the diversity of subject. 7) Display hinted from nature satisfied the mental desire of the human beings to be assimilated with nature. The formative characteristic presented the new possibility of combination of display with arts through the avant-garde sensation. Sale's room, or the marketing space was to be sublimated to three dimensional art space, which enhanced the image of sale's room, furthermore meeting the demand of moderner's lifestyle.

  • We examined whether visual perception related to consumption norms could influence food consumption and satiety by using modified soup bowls with elevated bottoms. Twenty-six healthy women (BMI 19.9 $kg/m^2$ Age 24 yr) participated in the study once a week for 2 weeks. The subjects were served beef shank soup in one of two soup bowls (180 g soup in the modified bowl or 250 g soup in the normal bowl). The results showed that subjects who ate from the modified soup bowl consumed less soup (135.3 kcal vs 180.0 kcal, P<0.001) and had lower total energy intake (390.6 kcal vs 438.1 kcal, P<0.01) than those who ate from the normal soup bowl. However, despite consuming fewer calories, satiety levels of those who ate from the modifed soup bowl were not significantly different from those using the normal soup bowl. In conclusion, these results indicate that the modified soup bowl which created a distorted visual perception ot the amount of soup in the bowl leads to decreased soup intake and total energy intake without altering satiety. The reduced amount of soup in the modified soup bowl may also implicitly suggest what might be interpreted as an appropriate amount to consume, and also in essence suggest reduced consumption norm.

  • OP-Art was not appreciated by painters and art critics. and according1y has been forgotten in art history. But recently Op-Art is revitalized in fashion and is in its palmy days. This study intends to re-assess the value of Op-Art, by reviewing its influence on fashion design in the post-modern society To this purpose, conceptual characteristics of Op-Art was analyzed. And then, on the bases of these characteristics, the figural characteristics and the meaning of Op-Art in fashion design of post-modern society was re-explained. Op-Art is characterized as an art of flatness of picture plane which uses repetition of simple forms and colors. It is also based on trick of visual perception. Finally. it creates an impression which is flickering or vibrating by means of optical illusion. These characteristics give birth to some features such as simplicity. anonymity and mobility in the Op-Art fashion. The meanings of Op-Art in fashion design in post-modern society are as follows. First, repetition of simple units employed in Op-Art produces feeling of simplicity. which makes the Op-Art fashion works perceived as polysemy. In other words, the feeling of simplicity can be interpreted In diverse perspectives within the social context of our society. The material civilization and technology civilization, which causes the alienation and standardization of man. can be the backgrounds of the Op-Art fashion. Second, Op-Art is an art based on perspectives of spectators. Anonymity in the Op-Art fashion enhances participation of spectators. which gives Op-Art a sense of affinity. Third, through the feeling of mobility created by optical illusion techniques. the Op-Art fashion expresses the opposition to the ideal body image made by power group. In post-modern society, Op-Art in fashion gives new meaning to art. Op-Art in fashion proposes new roles of artist and spectators, and new concepts of art related with roles of human beings. Through general sensibility of men, Op-art in fashion can express new recognition of the post-modern society.
