현재 흔히 사용하는 길찾기 앱은 대부분 2D 로 이루어져있어 초행길인 사람들이 길을 찾는 데 어려움이 있다. 특히 외국인들의 경우 길을 물어봐도 복잡한 길을 정확하게 알려주는 것은 한계가 있다. 따라서 본 논문에서는 외국인들에게 서울의 명소들을 카테고리 별로 나눠서 소개하고, 도보 길찾기와 대중교통 길찾기를 통합하여 제공하는 애플리케이션을 개발한다. 본 논문에서 개발한 애플리케이션은 특히 증강현실에 기반한 길찾기 서비스를 제공함으로써 외국인들이 도보 길을 보다 쉽게 찾아갈 수 있도록 한다. 본 논문에서 개발한 애플리케이션을 통해 외국인들은 서울의 유명관광지들을 보다 쉽고 빠르게 찾아갈 수 있으며, 목적지 주변의 시설들도 쉽게 파악할 수 있다.

The road name address system has been in effect in Korea since 2012. However, the existing address system is still being used in many fields because of the difference between the spatial awareness of people and the road name address system. For the spatial awareness based on the road name address system, various spatial datasets in daily life should be referenced by the road names. The goal of this paper is to link the road name address system with the wayfinding process, which is closely related to the spatial awareness. To achieve our goal, we designed and implemented a geometric matching method for spatial data sets. This method generates network neighborhoods from road objects in the 'road name address map' and the 'pedestrian network data'. Then it computes the geometric similarities between the neighborhoods to identify corresponding road name for each object in the network data. The performance by F0.5 was assessed at 0.936 and it was improved to 0.978 by the manual check for 10% of the test data selected by the similarity. By help of our method, the road name address system can be utilized in the wayfinding services, and further in the spatial awareness of people.

최근 정보 기술의 급격한 발전으로 스마트폰이 우리의 일상 생활에 점점 더 많이 들어오고 있으며, 사용자들은 많은 서비스들을 누릴 수 있게 되었다. 위치 기반 서비스(LBS)의 경우 스마트폰에 탑재된 위치 확인 기능을 통해 음식점 추천, 길찾기 등 개인형 맞춤 서비스를 제공하며, 사용자는 간단한 동의를 통해 자신의 위치를 LBS 서버에 전송하게 된다. 이는 사용자의 개인정보 침해의 요소가 될 수 있으며, 사용자의 민감한 정보가 공개될 수 있다. 따라서 본 논문에서는 사용자의 경로 데이터의 민감 정점을 보호하고, 통계적 질의를 할 때, 절대적으로 개인정보를 보호할 수 있는 방법을 제시한다.

Recently, Location Based Service including tracking and way-finding services has been activated rapidly in the ubiquitous computing environment. According as the ubiquitous computing environment is developed, various types of sensor to acquire various data including location of the moving object are used widely, and acquired sensor data becomes abundant. However, the existing location management system based on a single location sensor is difficult to support LBS efficiently in the ubiquitous computing environment. In this paper, therefore, we propose the location management system in the ubiquitous computing environment that can manage the location data and the various sensor data efficiently. In addition, the location management system adopts the core technology for efficiently storing and transferring a large-volume of various data such as location data and for efficiently processing the various requests from a variety of servers and sensors. Especially, our architecture that is presented in this paper can support context-aware services and autonomous services efficiently in the ubiquitous computing environment.

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.

The mobile augmented reality(MAR) market is rapidly growing with following the sudden rise of the metaverse. However, research on improving user experience in mobile augmented reality environment is lacking. This study aims to develop the usability principles of an AR-based smartphone app. The research conducts following methods. 1)The characteristics of MAR were understood to identify usability elements of AR apps. 2)Usability principles were collected through analysis of case studies on the usability of AR and the 14 usability principles were developed through in-depth interviews with experts for the purpose of chunking. 3)To verify the 14 developed usability principles, evaluation items were composed based on the usability principles and usability evaluation survey was conducted. Consequently, significant differences were found in immersivity, presence, efficiency, satisfaction, playfulness and It was verified that the developed usability principle is useful in developing AR based smartphone apps. This study is meaningful in that it conducted the basic research of mobile AR usability principles

The subway is one of the representative urban public transportation systems. Since its being opened in 1974, the Seoul Subway has been continually extended, and new lines are being added in the metropolitan and outskirt areas, even at present. As a result, the numbers of transfer stations and transfer sections have been significantly increased, making the usage of the subway system more and more complicated. In the transfer stations with big floating population and overlapped flows of traffic in the subway, passengers want their movements to be more precise and faster, without taking the wrong trains by mistake. Therefore, the visual information system for the subway inside the stations is extremely important. At the same time, the visual information system is required to be easy to understand and use, even if the passengers do not have previous experience of using the subway. In this research we studied the problems existing in the visual information system which is currently working in the subway system, and suggest the direction of the improvement of the subway service based on our studies. This research was mainly performed at Sindorim Station, one of the busiest stations in Seoul Subway with huge floating population and complex transfer sections. The purpose of this research is the investigation of behavioral and recognitive characteristics of passengers in the transfer sections through preceding research and qualitative analysis, to draw the direction for future improvement of the current system and suggest the improved experience of using the subway system.

Due to the growing popularity of mobile information technology, more people, especially in the general public, have access to computerized geospatial information systems for wayfinding tasks or urban navigation. One of the problems with the current services is that, whether the users are exploring or navigating, whether they are travelers who are totally new to a region or long-term residents who have a fair amount of regional knowledge, the same method is applied and the direction are given in the same way. However, spatial knowledge for a given urban region expands in proportion to residency. Urban navigation is highly dependent on cognitive mental images, which is developed through spatial experience and social communication. Thus, the wayfinding service for a regional community can be highly supported, using well-known regional places. This research is to develop the framework for urban navigation within a regional community. The concept of communal ontology is proposed to aid in urban regional navigation. The experimental work was implemented with case study to collect regional landmarks, develop the ontological model and represent it with formal structure. The final product of this study will provide the geographical information of a region to the other agent and be the fundamental information structure for cognitive urban regional navigation.
