The paper concerns with the visual illusion strength for the static and dynamic figures which are generated on computer CRT. The Vertical-Horizontal, Ponzo, and Muller-Lyer illusion are studied under various conditions of type, size, and background angle of figure. And the results are obtained through the Multivariate Analysis of Variance (MANOVA). This paper concludes that the size and background angle of figure generally effect on the visual illusion, and there is a significant difference between figure types. These results can be applied to eliminate the visual illusion in real design.

With the occurrence of interest in image-presentation that helps express one's individuality in several place in our society, it has affected make-up field. Now, make-up is getting to be recognized as a key role player that reflects our social and cultural concerns not only by presenting a appropriate one that is proper when to use and what for, but also presenting individualistic images that are able to express one's attractiveness free from a last plain concept that meant merely applying cosmetics to one's face is makeup. Like above, the reason that a change for consciousness of the function of make-up was possible is a noticeable outcome that results from the difference before and after make-up. In other word, with the help of Corrective Make-up that makes use of optical illusion, the analytic research for features could have been carried out systematically, therefore, women get to present their beauty of innate facial shape and features at their pleasure. The basic principles of the Corrective Make-up, which was introduced to satisfy the purpose of the existing make-up take advantage of lines and colors that are part of the optical illusion. The nature of direction and movement was expressed by the direction and angle of lines and the colors are also able to induce the variation of images depend on the whole color around them or contrastive color around. This thesis is mainly about optical illusion through lines that are part of elements that induce the optical illusion and deals with phenomena that occur when we apply lines that are part of design into the make-up. And this is written for the purpose of establishing the last basis of make-up more scientifically and systematically through the research for the variation when we apply the nature of lines into our features and deriving facial image variation from it. This is also for study into the role of make-up as for psychological effect that is able to make facial images look different when the optical illusion with possible visual errors is applied into it. In conclusion, we can say "Make-up is optical illusion through visual elements such as lines, surfaces, books, touch and so on."

The purpose of the study is to make experimental whether three-dimensional body (especially face) has illusion based on theoretical background of form dimensions and color bright among precedent multi-form illusion, using the function of computer simulation. To investigate illusion that factors of clothing design(line, color, material) effect face, as the following is tried to solve giving change to neckline, collar, scarf which is believed to influence near face. How to make experiment as follows watching in order 13 scenes of a pair of with basic design and experiment design. Then the data were subjected to analysis of variance and Duncan's multiple range test. The result of this studying as follows, 1. Face looks larger in complex neckline than simple neckline. The larger collar is the larger face looks. 2. In white jacket, illusion(the lower luminosity of scarf color gets, the brighter face brightness gets) is shown. In black jacket, also illusion(the higher luminosity of scarf color gets, the darker face brightness gets) is shown. 3. In experiment on hardness and softness of face impression according to the material of collar, collar of knit and fur gives us assimilation illusion bring softer impression of face.

When a human-being gets a wrong perception about any object is a misunderstanding and what they feel through sense of sight is an optical illusion. The study about those illusions have been given out to not only the fields of fine art, design, and animation but also psychology First, this paper puts in order an op art, influenced in fine art and design, and animation using persistence of vision, relating an optical illusion. Second, it analyses the theory of art form using an optical illusion about brightness, saturation, contrast and luminosity of color. Finally, it makes an experiment of standard of perception on students. The study of art form using an optical illusion is another way to represent fine art comparisons and visual image including animation.

The virtual reality(VR) technology can provide various stimuli, including, visual and auditory stimuli, simultaneously in the virtual environment and encourage the user to interact. Virtual reality is a set of computer technologies, which when combined, provide an interactive interface to a computer generated world. In this world the subject can see, hear and navigate in a dynamically changing environment in which he participates as an active player, by modifying the environment according to his will. Moreover, the subject can get a feeling for the virtual environment in much the same way as one feels real life situations. In the real world, a plethora of information from various modalities may be in conflict, and modulate each other to form an illusion. In this study we investigated whether a tactile illusion on a real hand could be evoked by a virtual stimulus, the time required to generate this illusion and its duration. This study shows that the illusion occurred, and that was correlated with presence score in the virtual environment.

This study aims to identify the differences of body image when the stripe direction and width change of semi-tight skirt. The semi-tight skirt pattern was made using the standard size of a women in their 20s. 12 semi-tight skirt models combining 6 kinds of stripe directions and 2 kinds of stripe widths were made using CLO 3D virtual clothing system. The data was evaluated by 126 fashion design majors. The results were as follows; In accordance with the body image factor analysis of semi-tight skirt, three image factors were identified; whole body optical illusion, calf optical illusion and hip optical illusion. Among these factors, the whole body optical illusion factor is the most important factor. The body image depending on the stripe direction and width change of semi-tight skirt mostly showed the significant difference. In accordance with the analysis on the interaction effect of body image depending on the stripe direction and width change of semi-tight skirt, the whole body, calf and hip optical illusion factors showed the significance. The interaction of body image had independent influence on all factors of stripe direction and width. In particular, the interaction of stripe direction and width had the most significant influence on the whole body optical illusion.

Even though modem ideal body type is rather tall and slim one, most of women don't coincide with it exactly. The objective of this research was to study the optical illusion effect of clothing design line so that average Korean women can approach the modern ideal body type. This research also tried to show the more scientific method to make stimulus by computer simulation and to present quantitative data. For the experiment, 9 design variables were selected from design principal book as follows : waistline level, skirt length, horizontal line emphasis, vertical line emphasis. princess line, vertical stripe, horizontal stripe, diagonal stripe. Each variable was divided into 4 levels so that 36 experimental designs were made. Visual stimuli which same model was wearing each design were recreated by the CAD system. These were given to evaluating panels through slide projecter. Then panels compared experimental design with basic design by 'tall effect' and 'slim effect', All the data from the experiment were analyszed by ANOVA and DUNCAN test for multiple comparison to study significance, direction(positive or negative), degree, proper extent of optical illusion effect. The result showed that some designs have optical illusion effect to make better look. In addition, it proved that the stronger design variable does not mean the more optical illusion effect and there was proper extent which produce the best illusion effect in each design variable.

Two experiments were conducted to examine how additional dotted lines and peripheral stimulus to the caf$\grave{e}$ wall illusion affect on the degree of perceived tilt (amount of illusion) and confidency of illusionary perception. The experiment 1 tested the effects of adding mortar (solid line) and bright contrast dotted lines to the borderline of 3 layers of blocks, which are consisted of black and white blocks. On the experiment 2, effects of adding peripheral stimulus on caf$\grave{e}$ wall illusion were tested. The results of experiment 1 showed that adding dotted line on the borderline mortar between blocks has additive effects on confidency of illusory perception. However, no effect on perceived amount of illusion was noted. On the other hand according to the results of experiment 2, adding blocks did increase amount, but not confidency of illusory perception. These results imply that the perception of caf$\grave{e}$ wall illusion is related with response of orientation selective neurons.
