The communication designer in the multimedia age should have a consideration that the sound also can be an important expression element to transmit ones thought as well as the visual sense like color, shape and motion. As you already know, someones thought can be better understood when transmitted to others using the visual and auditory senses together than using the visual or auditory sense alone. The meeting of sight and hearing bases on the synesthesia. For example, low sound reminds a person of dark color and high sound usually reminds light color. And a percussion instrument reminds a person a circle and melody reminds a line. The visual and auditory senses In communication of the multimedia age should act as an independent expression element gotten out of the synchronizing that just serves simple sight and related sound at the same time. Interaction between sight and hearing arose a different emotion that cannot be happened just by one element alone. So, the programs of communication design education in this multimedia age should fulfill the requirement that it can develop ones expression ability through the understanding of interaction between sight and hearing. In this study, we suggest the education programs Classified into following categories; audio visual Gestaltung, audio visual moving graphics, audio visual design.

A two dimensional point light source array can replace both the viewing zone forming optics and the back light panel in the contact-type 3 dimensional imaging systems based on LC panels. This replacement can make the system structure of the 3 dimensional imaging systems no different from that of the conventional LCD and can reduce undesirable visual effects caused by the viewing zone forming optics. The problem with the point light source array is the visual quality deterioration of the system due to the non-ideal nature of the array.

Light is an essential element which make it possible for men to see things, and its important for painter cannot be too much emphasized. light has significant meanings in the history of painting as well as in human life. light playa an essential role in creating three- dimentional objects. Light has not only spiritural, psychological , and formative meanings but also in. itself in the field of drawing. In general, a study of light and colors should be understood not merely as visible effects but as something unconscious involving psychological experiences and spiritual symbols, thus, as a very subjective phenomena. The article analyzes new meanings and roles of light in modern area, examining ways in which studies of light has been performed. It also deals with the meaning and effects of light revealed in the history of oriental and western paintings, and their influence on modern illustrations through case studies in order to provide an opportunity to have a new understanding of light.

Because Image on the CRT change under different illuminants, human is difficult to see original color of object. If what is information of used illuminant on capturing object know, image can be transformed according to viewing condition using the linear matrix method. To know information of used illuminant at an image, the spectral radiance of illuminant can be estimated using the linear model of Maloney and Wandell form an image. And then image can be properly transformed it using color appearance model. In this paper, we predict the spectral radiance of illuminant using spectral power distribution of specular light and using surface spectral reflectance at maximum gray area. and then we perform visual experiments for the corresponding color reproduction according to viewing condition. In results, we ensure that the spectral radiance of illuminant at an image can be well estimated using above algorithms and that human visual system is 70% adapted to the monitor's white point and 30% to ambient light when viewing softcopy images.

In recent years, the digital media environment has begun to diversify, with a greater focus being placed on user-centric design. With the development of digital technology, the digital media environment has formed a vast network of information, which supports interactive communication between people, creating a need for user-centric research. Mobile displays, as a representation of the digital media environment, have the advantage of mobility through the use of thin screen displays and low-performance image sensors, which allow for miniaturization and power saving. However, this results in reduced colour accuracy compared to large displays. This study investigates users' colour perception when using dark and light mode mobile displays. Colour perception was measured using a psycho-physical experiment, which controls each colour attribute based on the 12 colours of KS. The results were analysed to determine whether there is a difference in colour perception between dark mode and light mode, and if the difference was statistically significant. Future research directions based on the results are then discussed.

This paper describes a game called the "robot hopscotch game" which uses mobile robots. In this game, a mobile robot moves on a board which consists of a number of square cells. This is similar to the usual hopscotch game in which a human player hops through a course on the ground. In the robot hopscotch game, each cell has a visual light communication unit. The unit sends identification signal and the robot which moves over the cell receives the signal for location recognition. In the game, a human player or a human operator competes with a robot or other human player on how accurately and fast they move to a goal location passing through the given way point cells. People played the game at the RoboWorld 2008 which was held at COEX Seoul, on 16th to 20th of October 2008. The replies to the questionnaire to the users show that users have interests on the game and expect further expansion of robot use though they are not in favor of the robot's outlook and they feel inconvenience on manipulation of the robot.

As the information-oriented society makes progress, the role of Image has much influence on human being in space as a medium for information delivery and a means of artistic communication. These influences are appeared as expressional characteristics of the image such as the reproducibility of reality and unreality in the real world, the synchrony of expression of time, visual formality, a sign and the transmission of moaning. For these, the investigator examined the meaning of image in aspace, taking into consideration of the interrelationship of image, space, and human being. As study findings show, the expressional characteristics of image in space have such visual effects as a space in which pictorial formality and object exists, in which the mutual understanding of communication exists, and that realizes immaterial membrane in the aspect of time and space, according to the electronic light, color, and formation of the image media. In addition, it become clear that the characteristic could be staged on various circumstances by constructing the relationship between an object and a point of time interactively with bidirectional communication through combining technology and art. This suggests that the image develops as the form of sensory communication via interacting of space and human being.
