This study was conducted on the visitors regarding their usage and evaluation state of the interpretive media which is utilized as a self-guide environment interpretation for the purpose of accumulating basic data for the park management. A questionnaire survey was chosen and the 275 valid samples among them were analyzed. The socioeconomic and behavioral characteristics of the visitors turned out to be similar with the results from another visitor survey in the same site. Among those who used the interpretive media, the largest proportion(77%) used the information board resources of the park; the usage rate of interpretive labels of woody plants, interpretive signs of cultural assets, and LED signs were shown to be relatively high. The usage of park brochures, park web sites, visitor center exhibits, and bulletin boards were less than 40% each. Visitors were asked to evaluate the importance and performance of the nine interpretive medias using a Likert Scale whose value ranges from one to five. The result recorded averaged above 4, which proved that the respondents were perceiving the importance of all forms of interpretive media greatly. The performance of interpretive media was also evaluated as affirmative, except the visitor center exhibits.

This study proposes a method to quickly and accurately acquire distance information on direction signs. The proposed method is composed of the recognition of the sign, pre-processing to facilitate the acquisition of the road sign distance, and the acquisition of the distance data. The road sign recognition uses color detection including gamma correction in order to mitigate various noise issues. In order to facilitate the acquisition of distance data, this study applied tilt correction using linear factors, and resolution correction using Fourier transform. To acquire the distance data, morphological operation was used to highlight the area, along with labeling and template matching. By acquiring the distance information on the direction sign through such a processes, the proposed system can be output the distance remaining to the next junction. As a result, when the proposed method is applied to system it can process the data in real-time using the fast calculation speed, average speed was shown to be 0.46 second per frame, with accuracy of 0.65 in similarity value.

현재 사람들이 원하는 목적지를 가기 위해 스마트 폰의 여러 지도 애플리케이션들이나 이정표를 이용한다. 그러나 2차원으로 나타나는 스마트폰의 지도 애플리케이션들로 3차원인 현실의 방향을 파악하기란 쉽지 않고, 이정표 또한 안내 가능한 방향, 게시되는 언어의 수가 제한되는 등의 문제가 있다. 본 논문에서는 이러한 문제를 보완할 수 있는 구글 맵 API를 이용하여 공간적으로 방향을 안내 해주는 시스템의 설계 및 개발 내용에 대해 기술한다. 이 시스템은 구글맵 API의 검색 기능을 통해 얻은 목적지를 안내판이 회전하여 이용자에게 방향과 거리를 안내함으로써, 3차원인 현실에서의 공간적 방향을 파악하는데 도움을 준다. 또한 기존의 이정표와 달리 새로운 장소에 대해 소프트웨어적인 업데이트만 실시하면 되므로 유지비용을 줄이는 효과를 기대 할 수 있다.

공항은 다양한 시설들이 혼재되어 있는 복합 공간으로 원하는 장소로 이동하기 위해서는 지도나 표지판뿐만 아니라 유·무인 안내 서비스를 이용하는 것이 필수적이다. 그러나 이러한 시설 안내 서비스는 이용객의 대다수를 차지하는 비장애인을 기준으로 설계되어 있는 것이 대부분이며, 특히 청각장애인은 음성 언어인 한국어를 통한 의사소통이 어려워 이러한 안내 서비스의 사각 지대에 놓여있다고 볼 수 있다. 본 논문에서는 청각장애인을 대상으로 공항 내 시설 위치 안내 서비스를 제공하는 키오스크를 구현하기 위해 마커리스(makerless) 한국 수어 인식 기술을 적용하는 방법을 제안한다. 기존의 알고리즘들이 수어를 인식하기 위해 사용자의 신체에 마커(marker)를 부착하거나 사용에 제약이 있는 깊이, 자기장 센서 등을 활용한 데 반해, 특징점 기반의 인식 기술은 별도의 마커 없이 RGB 영상만을 활용하여 수어를 인식하기 때문에 사용자의 편의성을 극대화할 수 있는 방법이다. 영상 기반의 마커리스 수어 인식 기술을 위치 안내 키오스크에 적용함으로써 청각장애인이 다른 사람의 도움 없이 공항 시설을 쉽고 안전하게 이용할 수 있도록 지원할 수 있으며, 나아가 배리어프리 (barrier-free) 공항을 구현하는 데에 큰 도움이 될 수 있을 것으로 기대된다.

There are increasing needs to provide sufficient information on road directions through road signs for expanding cities and traffic networks. Improving efficiency of direction guidance information from road signs not only requires criteria for but also systematic approach to selecting place names that appear on road signs. As such, this paper looks at road direction information from existing road signs that leads to Suwon and investigates whether the current system of road signs provides efficient, systematic and continuous direction information for road users to easily reach their destination. In this paper, Suwon's city hall is set up as the final destination, which is linked from five other cities, Anyang, Osan, Ansan, Yongin and Seongnam. The paper attempts to find out whether there is continuity and suitable number of road signs for direction information by analyzing the road signs between these 5 cities and Suwon with respect to direction, direction advance notice and direction guidance. It is found that drivers cannot easily find the needed information on their destination from the existing road signs and that continuity of selected place names that systematically appear on road signs is insufficiency. In addition, direction guidance on road signs is problematic, because the appearance frequency of road signs is not adequate and the continuity of road signs is not effective. Moreover, there is insufficient information on local direction guidance for immediate destinations on road signs with respect to turning left or right or going straight.

Recently, there are increasing needs to provide sufficient information on road signs for expanding cities and traffic networks. Improving efficiency of direction guidance information from road signs not only requires criteria for but also systematic approach to selecting place names that appear on road sings. As such, this paper looks at road direction information from existing road signs that leads to Suwon and investigates whether the current system of road sings provides efficient, systematic and continuous direction information for road users to easily reach their destination. In this paper, Suwon's city hall is set up as the final destination, which is linked from five other cities, Euiwang, Ansan, Hwaseong, Osan and Yongin. The paper attempts to find out whether there is continuity and suitable number of road signs for direction information by analyzing the road signs between these 5 cities and Suwon with respect to direction, direction advance notice and direction guidance. It is found that road users cannot easily find the needed information on their destination from the existing road signs and that continuity of selected place names that systematically appear on road signs is insufficiency. That is to say, the findings of the paper are that while it is easy for road users to find place names that are classified under land marks or the first-class selection of place names on road signs, it is difficult to obtain information from road signs on place names that are grouped under the second or third class. In addition, direction guidance on road signs is problematic, because the appearance frequency of road signs is not adequate and the continuity of road signs is not effective. Moreover, there is insufficient information on local direction guidance for immediate destinations on road signs with respect to turning left or right or going straight. Hence road signs in urban area need systematic improvement to find easily some destination.

This study aims to reveal path selection strategies and individual differences in a navigation task. Two experiments were presented that studied human route planning performance as well as the cognitive strategies and processes involved. For the outdoor task, university students were asked to select a route based on the instruction, i.e. to find the best route from the campus main gate to the Education Building for conference visitors by locating eight signposts. Results indicate (1) that locations of signposts were selected preferably at decision points where the traveler needs to make a choice and starting/ending points of the navigation task and (2) a variety of route planning strategies considering efficiency goal (e.g., the shortest path), environmental characteristics (e.g., fewest turns), and aesthetic purpose (e.g., most scenic) were used. It is notable that some participants took into account more than one path by locating one or two signposts on an alternative route while others preferred a linear route connecting signposts between the start point and the destination. Prior to the main experiment, the same participants were asked to complete the same task inside the classroom to investigate changes in strategies between two tasks. Participants often tend to place signposts at more regular intervals for the indoor navigation task than the same task conducted outside.
