TV display which existed only in house started to show up out of house around us and now it found naturally its place in everywhere like street, bus, subway and elevator. It is called digital signage which showed up through digitalization of sign, that is, sign board and bulletin board. The distinction of digital sign from existing signs is that the latter one should go through physical process like removal after installation every time its contents are changed but the former one can produce its various outputs flexibly once it is installed. Also existing sign may be static image or 2 or 3 pieces of image to express simple motion while digital sign can contain multi media contents luxurious in design and motion. This paper confined the range of contents in digital signage in bus and subway. It needs to analyze characteristics of mass transportation-people of use, consumer by place and time, accommodation environment for consumer etc and arrange planned contents along with time and place. Developments of dedicated contents suitable to those digital signages will harmonize with place and time and promote the realm of digital signage which provides variety of experience to consumer and with which communication is possible and which is distinctive. Furthermore we may expect the birth of smart signage as a new media, in which fun and art are combined.

Purpose The purpose of this study is to analyze the influence of individual characteristics and household environmental factors on OTT consumption, based on the uses and gratifications theory and family systems theory. It seeks to provide strategic and policy insights by incorporating key user attributes and environmental determinants affecting OTT consumption. Design/methodology/approach This research employs multilevel analysis utilizing data from the 2023 Media Panel Survey. The analysis incorporates multilevel data, combining individual and household levels. The Media Panel data, provided by the Korea Information Society Development Institute, encompasses information on households and their members aged six and above. Findings The findings indicate that individual OTT consumption significantly varies based on household environment. Residents of larger cities demonstrated higher OTT expenditure, whereas those in smaller cities exhibited greater OTT usage. A positive correlation was found between the number of OTT services used within a household and individual OTT usage. Interaction effects revealed that residents of smaller cities concentrated more on specific OTT types such as AVOD and AVOD+SVOD,AVOD+SVOD, leading to higher expenditures. While AVOD preference generally resulted in lower OTT expenditure, it increased with higher household OTT service usage. These results underscore the importance of considering both individual preferences and household environments in comprehending OTT consumption, providing a basis for developing customized media policies and content strategies.

A game designer is the initial design of the quest based on narrative. It is important that to predict game character of play experience to establish these static content. This paper deal with player's affective interaction distinguishing among game characters are perform quest-play based on their characteristic status. To achieve this, First of all, previous studies regarding pre-visualization of narrative structure for other visual media are reviewed. Secondly, it is specified that quest-play experience and player's cognitive behavior. At last, these features of status by character were pre-visualized with QUG(Quest Unit Graph), which could be represented differences in precess of quest-play through analysis on world of warcarft game. Previous research is about of numerical balance in terms of character's achievement, whereas this study is meaningful that is proposed that visual model of quest-play interaction focused on narrative structure to predict game designer's architecture of quest experience.

These days, with the advent of digital broadcasting, media environment offers users an opportunity to enjoy differentiated contents in a more aggressive fashion through user-media interactions based on computer technology. In fact, the development of contents which can induce spontaneous acts from users such as outdoor ads which use certain sensors and devices and exhibition halls has been active. With the development of low-price motion recognition devices, people have been able to enjoy diverse interaction-applied media by recognizing users' motion data without body contact. In this paper, we developed an interactive media player that can recognize the user's motion and control the video in the web service environment without installing a specific program. In addition, we set user motion recognition range and developed a user motion recognition algorithm suitable for the Leap Motion equipment installed in the kiosk. The results of this study can be experienced by various interactive media such as interactive tourism, education, and movie contents in kiosks that can be installed in public places.

Recent days, touch interaction interface is the most widely used interaction interface to communicate with digital devices. Because of its usability, touch technology is applied almost everywhere from watch to advertising boards and it is growing much bigger. However, this technology has a critical weakness. Normally, touch input device needs a contact surface with touch sensors embedded in it. Thus, touch interaction through general objects like books or documents are still unavailable. In this paper, a human-object interaction framework based on RGB-D camera is proposed to overcome those limitation. The proposed framework can deal with occluded situations like hovering the hand on top of the object and also moving objects by hand. In such situations object recognition algorithm and hand gesture algorithm may fail to recognize. However, our framework makes it possible to handle complicated circumstances without performance loss. The framework calculates the status of the object with fast and robust object recognition algorithm to determine whether it is an object or a human hand. Then, the hand gesture recognition algorithm controls the context of each object by gestures almost simultaneously.

The development of digital technology has not only led to the development of expressive technology, but also to change in the process of production, expression media, production formats and methods, and communication with the audience. In one form, motion poster using LCD display instead of paper poster was introduced. This not only suggests the generation of posters with sound and movement on the ground, but also the possibility of expansion using the features of a platform called LCD displays. As part of this extension, this paper focuses on the "interactions" element and suggests a new interactive motion poster.

Arts gains a new relation as the new academic area that deals with living organisms and through this technology, it affects everything, such as the body, entity, consciousness and unconsciousness to bring an overall change. Based on this premise, arts require a different interpretation from the previous product-focused interpretation or the analysis focusing on the aesthetics. As the result of arts using the scientific methods, I examined the changes of the arts semantics and how it evolved with what kind of contents and characteristics. The net art with the internet base also form a close relationship with the social and cultural codes. In categorizing the social issues and the topical discussions with semantic factors that evolve from the digital biological perspective, it can be divided into four types of complex interaction, positive feedback negative feedback, and amplification of unsettledness. Based on the characteristics of the multimedia and the interactive reaction, the technique and the imagery amplify the message through a spatial and timely meeting in a mutual repletion. In other words, the emotional communication is used to attempt the messages from the products and the expression in various methods.

After arranging the general usability evaluation criteria of existing VUI researchers, this study verified how appropriate these criteria are for AI VUI specialized in navigation and the priority of their suitability. The VUI used in this study was analyzed through a survey from a total of 195 Chinese users after analyzing the navigation VUI used in China. As a result of the analysis, the usability evaluation criteria of the navigation VUI were extracted from three sub-factors of 'task accuracy', 'function satisfaction', and 'information reliability' in verifying conformance with general VUI evaluation criteria. With the recent advent of self-driving cars, safety and response speed are becoming very important, so Chinese users also ranked responsiveness as the top priority in VUI design, and the importance was also found to be high. Also, both men and women have the highest reactivity and the lowest multiplicity. VUI requires a convenient and natural interface to understand the intention between two objects through usability evaluation and verification in order to have effective interaction between humans and machines.
