Wayfinding is a 'Process solving problem to find destination', and it is important to select spatial data for optimal way. Recently, due to the complexity of space and the expansion of the medium of the wayfinding service, it is necessary to the approach on the information design for them. Therefore, the purpose of this study is to propose a meta guideline on the information design for the design of orientation sign, which is an important cognitive clue in the wayfinding. It was conducted in 3 stages, First, a design process was proposed and design elements were derived for each step by literature research related to information and sign design, and analysis of manual for signage design. Second, a meta guideline for information organization and visualization in the three-stage design process was proposed by FGI and analysis. Third, the meta guideline was applied to the sign design on an area for user evaluation to inspect the applicability of the meta guideline. Through the user questionnaire, the possibility of applying the guideline for visualization of directions and spaces, information hierarchy according to spatial characteristics and information priority was identified. It is meaningful in that necessary element for signage design are systematized centering on the process and that it presents a macroscopic methodology according to spatial characteristics.

Augmented reality applications offering location based service on smart phone require attention to users and new usability evaluation methods. The aim of this paper is to introduce new usability principles for application development and usability evaluation, and conduct expert evaluation on the augmented reality applications. We created a set of usability principles by analyzing characteristic of augmented reality applications, and conducted expert evaluation on three augmented reality applications primarily used by smart phone users. In expert evaluation and filtering procedure, we identified six usability problems that three applications have in common and the improvement guideline for the usability problems. The results of expert evaluation was verified by user test with a prototype that was developed using the guidelines. It is expect that the results of this study can be presented usability principles of the augmented reality application and a method of usability evaluation in the middle of new technology development process.

Recently, with the market of smart phones slowing down, more attention is paid to wearable devices. It was suggested that 2013 was the "year of the smart watch", due to that the majority of major consumer electronics manufacturers were undertaking work on a smart watch device. However there are still many issues on the interaction and interface design of smart watches. This study reviewed related literatures and evaluated the interaction methods, interface and content design of current smart watches. Based on that, future research directions were proposed. The research results have significant meanings for the guidance of future directions of smart watch.

The advance in mobile devices such as smartphone, wireless networking, and Internet technologies enables many organizations to improve drastically not only the ways of carrying out every job activity but also their business processes and operations management. As the effort to work smart utilizing the technological change, they are interested in the implementation of Smart Work environment. In this paper we examine several types of smart work and their service scenarios. We also describe the structures of networking and system configurations for building up the smart work environment. These study results may be useful as reference materials for the successful implementation of smart work.

The purpose of this paper is to propose a smart work implementation strategy of Korean companies. Recently in Korea, the interest in smart work is growing and actively promoting but the introduction of private enterprise strategy is absent. However the smart work has been highlighted several issues. In this paper, among the issues, we studied the strategy for introducing smart work system with respect to the related research and literature on strategies and guidelines that may be introduced to the system. With reference to the actual introduction of the basic directions for the procedure proposed by the Korea Communications Commission, we try to review the operating guides and to propose smart work 2.0 implementation strategy, framework and some procedure.

스마트폰의 확산이 증대되고 있으며, 누구든지 모바일 앱을 개발할 수 있는 환경이 제공되고 있다. 모바일 앱을 개발하는 개인 개발자들은 접근성과 이해성이 좋고, 보안성이 고려된 표준 가이드를 적용하여 앱을 개발해야 한다. 이는 오류 발생률 감소 및 코드 수정에 소비되는 시간이 절약될 수 있는 모바일 앱을 개발하는데 도움이 된다. 하지만 개인개발자들을 위한 적절한 가이드가 존재하지 않는 실정이다. 본 논문에서는 개인 개발자들이 쉽게 접근 할 수 있으면서 보안성이 고려된 표준 가이드를 제시하기 위한 개발 방법론을 제시한다.

As an energy network infrastructure, which is capable of integrating energy related services such as AMR/AMI, Smart Grid, and Smart Water Grid, the Smart Utility Network (SUN) enables a paradigm shift from user-oriented networks to device-oriented networks. The SUN has some similarities to sensor networks in application and network requirements. Therefore it is required to investigate and analyze thoroughly existing related work in advance to design new network protocols for SUN. In this paper we analyze service requirements and design considerations for SUN and then present a design guideline of new network protocols for SUN by investigating existing low power protocols, data aggregation methods, and in-network storages.

The aim of this study is to suggest development guidelines of educational smart application for the students with development disability based on Universal Design for Learning(UDL). The basic guideline set were organized by analyzing UDL studies on different media. The totally 35 preliminary guidelines which consist of 14 items of contents presentation, 12 items of education strategy and 9 items of education engagement were settled through review of smart contents expert developer and professors in special education. Based on the preliminary guideline, a survey was conducted to determine effective guidelines among end users which consist of the teachers who educate students with disability, parents with disabled children and professors in special education major. 3 categories and 20 guidelines are presented by analyzing survey result through excluding items whose importance factor were lower than average of importance.

Due to the development of communication technology and expansion of Intelligent Transport System (ITS), the car is changing from a simple mechanical device to second living space which has comprehensive convenience function and is evolved into the platform which is playing as an interface for this role. As the interface area to provide various information to the passenger is being expanded, the research importance about smart car based user experience is rising. This study has a research objective to propose the guidelines regarding the smart car user experience elements. In order to conduct this study, smart car user experience elements were defined as function, interaction, and surface and through the discussions of UX/UI experts, 8 representative techniques, 14 representative techniques, and 8 locations of the glass windows were specified for each element. Following, the smart car users' priorities of the experience elements, which were defined through targeting 100 drivers, were analyzed in the form of questionnaire survey. The analysis showed that the users' priorities in applying the main techniques were in the order of safety, distance, and sensibility. The priorities of the production method were in the order of voice recognition, touch, gesture, physical button, and eye tracking. Furthermore, regarding the glass window locations, users prioritized the front of the driver's seat to the back. According to the demographic analysis on gender, there were no significant differences except for two functions. Therefore this showed that the guidelines of male and female can be commonly applied. Through user requirement analysis about individual elements, this study provides the guides about the requirement in each element to be applied to commercialized product with priority.
