Due to the development of digital appliance, role of TV causes both-way by introducing IPTV, and SNS service causes big change of watching environment and residence environment. There are good conditions on the role of integrated control because it is arranged in the living room which secures movement most effectively and because family members can easily use, and the degree of use is high. Therefore, we infer user's needs by analyzing user scenario and current role of TV in home network environment. Primarily, we collect surveys of development scenario and technology which companies suggest TV applied by home network service, and secondly, we comparatively study scenario which the companies mentioned above suggest through observing user scenario, and study the role of IPTV in the future through actual scenario-based experiment by ethnography. After analyzing user scenario through case study and experiment, there are integrated device studies mainly in company study because it can be made up inside home, security and entertainment. On the other hand, there are patterns of user behavior by scenario experiment mainly in auto-tainment, security, and it showed that it is insufficient for interaction between TV and home media peripheral. Through this paper, we analyze context of home user, and based on this, we could suggest effective use of service development. Also after analyzing user form, we could know it also should be considered of ratio between activity inside home and activity outside home.

With the introduction of BIM and ICT technology, 'Cloud-based collaborative design support system' has been actively researched and new user interface is needed to support it. When developing the user interface, scenario - based design method is selected which based on the actual usage scenarios to anticipate the usage situation and reflect the user's requirements. However, since the existing scenario-based design technique is an inductive method, it is difficult to cover the usage situation of all users when creating the usage scenario. For this reason, there is a need for a new scenario creation method that can systematically create and modify scenarios instead of inductive methods. This study proposes a 'Multi-scenario-based design method' that complemented the existing method and verify its usability by applying it to the user interface development process of 'Cloud-based collaborative design support system'.

Recently, there has been a growing interest in user-centered smart city services. This study examines the spatial information type to derive a smart city service scenario through space - based communication and aims to establish a direction for user - centered experience factor scenario. The results of this study are meaningful for presenting basic data to suggest a space scenario where citizens can experience smart city as walking map and experience route applicable to future smart city test bed. In particular, we simulated the walking scenarios in the smart city test bed through Walking Map, which is tested the service direction based on user requirements. Through this study, we confirmed that smart city service through existing infrastructure can be used multipurpose. The spatial information and the experience factor linkage model and the walking map through the persona model presented in this study can be utilized as a preliminary scenario applicable to the future smart city test bed.

Variety of smart devices including smart phone have become and essential item in user's daily life. This means that smart devices are good mediators to get collecting user's behavior by sensors mounted on the devices. The information from smart devices is important clues to identify by analyzing the user's preferences and needs. Through this, the intelligent service which is fitted to the user is possible. This paper propose a smart service recommendation model based on user scenario using fusion context-awareness. The information for recommendation services is collected to make the scenario depending on time, location, action based on the Fusion process. The scenarios can help predict a user's situation and provide the services in advance. Also, content categories as well as the content types are determined depending on the scenario. The scenario is a method for providing the best service as well as a basis for the user's situation. Using this method, proposing a smart service model with the fusion context-awareness based on the hybrid sensing is the goal of this paper.

While the society becomes older, the quality growth on the service adequate to seniors is required. The service design is highlighted as a measure to improve the quality of service. And actually, success cases through the service design in various areas are globally introduced. In this study, a research is conducted to develop a service scenario to expand seniors' communication by applying the service design methodology. To analyze seniors' behaviors related to the communication, profiles are established by performing interviews with professionals and the qualitative survey to seniors. And based on the profiles, an idea workshop is conducted with multi-disciplinary experts to develop ideas for seniors' communication. The representative service is drawn by refining ideas. And the detailed service scenario and the video prototype are developed by concentrating one service scenario. The developed service scenario is anticipated to be utilized as a base material to develop services to expand seniors' communication in the future.

It is a story-based content creation service that provides any user with some proper contents based on a story written by the user in order to utilize a lot of contents accumulated on Internet. For this service, the story has to be described in computer-readable representation. In this paper, analyzing the structure of scenario, as known as screenplay or scripts, a structure of story representation, which is referred to as OpenScenario, is defined. We intend users to produce their own contents by using massive contents on Internet by the proposed method. The proposed method's OpenScenario consists two main parts, OSD (OpenScenario Descriptors) which is a set of descriptors to describe various objects of shots such as visual, aural and textual objects and OSS (OpenScenario Scripts) which is a set of scripts to add some effects such as image, caption, transition between shots, and background music. As an usecase of proposed method, we describe how to create new content using OpenScenario and discuss some required technologies to apply the proposed method effectively.

As the technology developed, the system is being developed as the structure that is adapted to the intelligent environment. Therefore, the existing situation information system couldn't provide satisfactory service to the user as it provides service only by the information which it received from the sensor. This paper analyzed the problems of the existing user intention awareness system and suggested user intention awareness system to provide a stable and efficient service that fits to the intention of the user compensating this. This paper has collected the behavior data based on the scenario of the sequential behavior course of the user that occurs at breakfast time in the kitchen which is the home domain environment thai is closely related to our lives. This scenario course also showed the flow that the goal intentional user intention awareness system acted that it suggested, and showed the sequential course processing the user behavior data by tables and charts.

The purpose of user participatory design is to project the images and demands of all the users of a school in person through their direct and active participation. Also, user participatory design is supposed to reduce the role of professionals who have led design to date and to expand the role of users and participants; thereby improving design quality in school construction. The study propose design realization methods using design camp courses and SNS based user participatory workshops. And The study propose on-offline based method and tool which are able to reflect diverse situations and purposes. Finally, the study proposed an application scenario for applying the above proposed methods efficiently in user participatory design. For the application scenario, the study proposed an SNS-based user participatory design method as the most appropriate for Korea.
