Most of the existing interactive arts or entertainment systems consist of the following three steps: 1. the system's prompting the action of the participant, 2. action of the participant, and 3. response of the system. They do not presuppose these successive processes are performed continuously and repeatedly, and they are designed to express the concept of the work in each interaction. The opposite approach is to transmit the concept of the work in a continuous and repeated experience. The authors propose "Adjustive Media" as a type of work based on this approach. Adjustive Media has a spiral model with feedback. When participants experience the work repeatedly, they can recognize the difference of results between each interaction, and they can under- stand more closely the intent of the designer. This paper will propose 3 design processes for Adjustive Media as design method, and will introduce the prototypes of Adjustive Media.

오늘날 기술 경쟁이 심화되면서 업체간 기술 격차는 큰 차이를 보이지 않고 있다. 그래서 각 기업들은 자사 제품의 경쟁력 확보를 위해 다양한 분야를 연구하게 되었고, 그 결과 소비자들에게 높은 기술력을 제공하는 것보다는 새로운 경험을 제공하는 것에 대한 중요성이 점점 부각되어 가고 있다. 그래서 본 논문에서는 PC 에서 웹 서비스(Web-Service)를 사용하는 사용자의 경험을 IPTV 에서도 경험할 수 있는 방법에 대해 연구하였고, 그 중 사용자들이 좀더 편리하고 쉽게 웹을 경험할 수 있는 Widget UI를 제안한다. 우리가 제안하는 IPTV 에서 웹 서비스를 제공하는 Widget UI 는 서로 독립적인 Widget 서비스들로 구성되어 있으며, Widget 서비스의 개수와 배치는 사용자에 따라 다르게 제공된다. 즉, 우리는 IPTV 를 위한 사용자 맞춤형 웹 서비스 제공 Widget 사용자 인터페이스를 제안한다. 또한 각 Widget 서비스의 정보 검색은 리모컨의 4 방향 키를 사용하도록 제공함으로써 사용자에게 사용의 편리성을 증대시키고 학습 피로를 감소시킬 수 있다. 이러한 학습 편의성과 사용 편리성을 사용자에게 제공함으로써 기존에 IPTV 에서 사용하기 힘들었던 웹 서비스의 사용성을 크게 향상 시키는 효과를 기대할 수 있다. 우리는 이러한 Widget UI 의 사용성을 객관적으로 평가하기 위해 UI 전문가들을 대상으로 전문가 평가를 실시하였으며, 결과 비교를 위해 다른 웹 서비스 제공 UI 들도 추가적으로 전문가 평가를 실시하였다. 전문가 평가 결과 본 논문에서 제안한 Widget UI 가 타 UI 들에 비해 높은 사용성 평가를 기록하였으며, 이 결과는 결국 우리가 제안한 Widget UI 가 IPTV 에서 웹 서비스 정보를 제공하는데 있어 효율적이고 적합한 방식임을 보여준다.

Previous studies on willingness to pay for digital content have mainly focused on audience factors and individual level. To complement the limitation of previous research, this study conducts a multilevel analysis to find the factors influence digital content purchases considering two axes: audience/media factors and individual/household levels. Using a sample of 10,172 individuals within 4,313 households, the analysis results show individual media factors including theater-going, experience with cloud services, and multi-screen service usage have the greatest effects on digital content purchases. At the household level, the media ownership factors that the number of laptops, wireless routers, and tablets have a greater influence than audience factors such as household size or household income. Our findings help scholars to enhance the understanding of individuals' media use considering household environmental factors and shed light on the importance of multi-screen service usage, and content providers to improve their digital content sales using multi-screen environment.

Recently, there are several active and vibrant studies on Realistic Media that try to provide the immersion and the presence by adding sensory effects to video. Because existing sensory effects on Realistic Media are produced through experts and automation programs on sensory effects, there is a limit to fill up the gap of user satisfaction which comes from the diversity of cybernauts. In this paper, we propose a method to improve the satisfaction with sensory effects by collecting and analyzing user's response information, and applying the result to the attributes of sensory effects. The proposed method allows you to produce the Sensory Effect Metadata effectively by analyzing users' biometric data and subjective satisfaction with realistic media experience, measuring the weighted value to revise the effects, and applying to the attribute of sensory effect. The experimental result shows that the proposed method improves the satisfaction with realistic content by generating the revised Sensory Effect Metadata in response to user's experiential feedback information.

A virtual reality is a virtual space constructed by a computer that provides users the opportunity to indirectly experience a situation they have not experienced in real life through the realization of information for virtual environments. Various studies have been conducted to realize virtual reality, in which the user interface is a major factor in maximizing the sense of immersion and usability. However, most existing methods have disadvantages, such as costliness or being limited to the physical activity of the user due to the use of special devices attached to the user's body. This paper proposes a new type of interface that enables the user to apply their intentions and actions to the virtual space directly without special devices, and test content is introduced using the new system. Users can interact with the virtual space by throwing an object in the space; to do this, moving object detectors are produced using infrared sensors. In addition, the users can control the virtual space with their own postures. The method can heighten interest and concentration, increasing the sense of reality and immersion and maximizing user's physical experiences.

The objective of digital broadcasting has evolved from providing a plain video service to offering a realistic visual experience. Technologies such as 3DTV and UHDTV have been suggested to achieve this new objective by providing an immersive and stereoscopic visual experience. However, owing to the high bandwidth requirements of such services, the broadcasting industry has faced a challenge to find a new transport mechanism for overcoming the bandwidth limitation. The standardization organizations, the Advanced Television Systems Committee, Digital Video Broadcasting, and Telecommunications Technology Association, have been working on the integration of broadcasting and a broadband network (IP) to resolve the bandwidth issue of realistic video services. This paper introduces a frame-level timeline synchronization and transport system target decoder model for providing a stable 3DTV service over a hybrid network. The experimental results indicate that the proposed technologies can be successfully adopted as a reference model in a broadcast-broadband hybrid 3DTV service and other IP-associated hybrid broadcasting services.
