  • The purpose of this study is to propose a design method for one-piece dress patterns with high body fitness through an appearance evaluation of one-piece dress patterns with the application of the 3D Virtual Clothing System known as i-designer. Measures consisted of an optical illusion effect in visual imagery and mutual influence according to a change in the length and princess line, in a silhouette of a one-piece dress. The data was assessed by a t-test and a multi-way ANOVA and factor analysis using SPSS 17.0. The results were as follows; The design of the study pattern was done by modifying the ease of the bust circumference, ease of the abdominal circumference, ease of the hip circumference, the position of the side seam line, and the appearance of horizontality in the hem line, which received a low evaluation in appearance evaluations of a one-piece dress pattern. As a result of analyzing the visual image according to a change in the length and princess line, in the form of a silhouette of a one-piece dress, four factors were selected; the whole-body optical illusion factor, the upper-body optical illusion factor, the bust optical illusion factor, and the lower-body optical illusion factor. As a result of analyzing the effect of the interaction in the visual image according to the design variables, the influence of the main effect was found to be great in each factor. In the upper-body optical illusion factor, a significant difference was not noted in the two-way interaction between the length and the princess line. However, the influence on three-way interaction among the length, princess line, and silhouette was significant.

  • The purpose of this study is to determine affects of hair colors on physical shapes and images through field survey and experimental research. For the purpose, this researcher surveyed 230 female college students residing in Busan about their dyed hair colors, and selected the subjects for the study. Then the researcher an experimental research on the subjects by suing test stimuli. Results of the study can be described as follows: Experiment of the Optical Illusion of Physical Shapes. For all items measured for the experiment, except four ones, if was found that hair colors provided significant efforts of optical illusion factor analysis, included horizontality, outlines of the body and face, a horizontal line of the shoulder, the length, verticality and a horizontal line of the face. According to hair colors, black made the body look slimmer and the face look apparent. White made the body height look low, the outline of the face look clear and the neck or shoulder look fleshed. Female college students whose hair color was orange looked unclear in the body silhouette, bright in the face and broad in the hip and shoulder. Other students whose hair color was red, attracting the line of vision upward most strongly, looked fleshed in the upper body and broad in the face. Finally, blue made the face look dark.

  • At present, naked-eye 3D appears more and more commonly on the facades of urban buildings. It brings an incredible visual experience to the audience by simulating the natural 3D 3D space effect. At the same time, it also creates enormous commercial value for city publicity and commercial advertisements. There is much research on naked-eye 3D visual effects, but for right-angle LED screens. Right-angle LED screen's brand-new expression method that has only become popular in recent years, how to convey a realistic naked-eye 3D effect through two LED screens combined at right angles has become a problem worth exploring. To explore the whole design ideas and production process of the naked-eye 3D impact of the right-angle LED screen, this paper is a preliminary study aimed at understanding the performance principle and expression features. Before the case analysis, first, understand the standard virtual 3D space construction techniques. Combining it with the optical illusion phenomenon, according to the expression principle of the naked-eye 3D effect of the right-angle LED screen, it can be summarized into seven expressions: Shadow, Color contrast, Background structure line, Magnify object, Object out of bounds, Object floating, Fusion of picture and background. By analyzing the optical illusion phenomenon used in the case, we summarized the main performance characteristics of the naked eye 3D effect. The emergence of right-angle LED screens breaks the limitation of a single plane of optical illusion art, perfectly combines building facades with naked-eye 3D visual effects, and provides designers with a brand-new creative platform. Understanding its production principles and main expressive features can help designers enter this innovative platform better.

  • Background and Objectives: Balance control is maintained in stationary and dynamic conditions, with coordinated muscle responses generated by somatosensory, vestibular, and visual inputs. This study aimed to investigate how the vestibular system is affected in the presence of an optical illusion to better understand the interconnected pathways of the visual and vestibular systems. Subjects and Methods: The study involved 54 young adults (27 males and 27 females) aged 18-25 years. The recruited participants were subjected to the cervical vestibular evoked myogenic potentials (cVEMP) test and video head impulse test (vHIT). The cVEMP and vHIT tests were performed once each in the absence and presence of an optical illusion. In addition, after each test, whether the individuals felt balanced was determined using a questionnaire. Results: cVEMP results in the presence of the optical illusion showed shortened latencies and increased amplitudes for the left side in comparison to the results in the absence of the optical illusion (p≤0.05). When vHIT results were compared, it was seen that the right lateral and bilateral anterior canal gains were increased, almost to 1.0 (p<0.05). Conclusions: It is thought that when the visual-vestibular inputs are incompatible with each other, the sensory reweighting mechanism is activated, and this mechanism strengthens the more reliable (vestibular) inputs, while suppressing the less reliable (visual) inputs. As long as the incompatible condition persists, the sensory reweighting mechanism will continue to operate, thanks to the feedback loop from the efferent vestibular system.

  • In this study an experiment was made using the function of computer simulation os to whether the phenomenon of optical illusion takes place also in clothing on the human body three-dimensional space through the case study of the Gestalt illusion of planar con-traction and expension by amodal completion in perceptual organization. One woman of latter 30s was selected as the experimental subject. She was made to wear the experimental clothing and then the frontal picture was projected of in the experimental clothing which was scanned into the com-puter. For the sake of the contractive experiment 5 stages were divided by 5-15cm the thick-nes of the black vertical line in the center of the upper garmet as the variable and for the sake of the expansive experiment the skirt length was set as the variable. It length measured 50-90cm which was divided by 10cm into 5 stages and simulated using the CAD. The basic design and the experimental de-sign were made one pair and the pictures totalled 20 pictures such as ten pictures save the human body for the estimation of the up-per garmet alone and ten pictures for the ob-servation of the effect on the human body. The extimating panel consisting of 20 panellers estimated contraction/expansion in the estimation of the upper garmet and the tall effect/the slim effect in the estimation of optical illusion as the estimating factors on the 9-point scale. All the date from experiment were analyzed by ANOVA(analysis of variance) and DUNCAN'S multiple range. As a result the experimental designs all showed a significant optical illusion in comparision with the basic design.

  • This study is about the expression types and characteristics of Trompe l'oeil in modern fashion. The study defines the concept of Trompe l'oeil, examines the Trompe l'oeil in the surrealist works from which the Trompe l'oeil derives from, and analyzes the works that have emerged since 2000. The study used a collection of magazines such as Vogue, Gap, Fashion News, and the Internet. According to the findings, the expression types of Trompe l'oeil in modern fashion were seen in the human body, the wearing style, the details, and accessory effects of clothes. The modern fashion design using the Trompe l'oeil based on such external expressions was characterized by the following: first, the fashion design destroyed the concept of common sense and expressed the purity of the human spirit by revealing the human body hidden in clothes from the combination of clothes and the human body with surrealism. Second, the details or accessories of clothes were printed or painted as if they existed. Pleasure was expressed by applying Trompe l'oeil to the wearing methods and forms of clothes through the optical illusion of materials or colors. Third, the effects of an optical illusion were displayed by transforming and distorting the wearing style and reversing the front, back, exterior and interior of clothes; this optical illusion characterized the deconstruction expressed through the transformation of ideas.

  • In this study, in regard to the change of the paradigm to STEAM (Science, Technology, Engineering, Arts, and Mathematics), we have looked into the ways to apply scientific inquiry through the arts, discussed the educational implications for the ways to step forth with the science and the arts in educational field. In the development of the strategies related to the optical illusion arts, to make sure that the design-oriented science education to reach its goal to make effective teaching, students need to be understood in the method of the artistic designs. Totally it had two rounds for inspection about operation of the convergence with curriculum. As a result, students changed attitude to concentrate in class naturally while doing their art work, participating in person rather than simply looking. It is caused by the scientific approach to strategy of illusion arts. In addition, we could see that students change into a proactive manner as well as teachers comments that they are communicate and make a complete the work with others. A lot of researches give that science can provide the ideas as a method to arts, arts can provide creative ideas to science, but it is still lacking that research can be applied to education specifically on how to. An efforts in the number of collaborative research will continue to introduce, as this study STEAM of science and arts in the field of education be shifted paradigm.
