Screen climbing is a kind of screen sports. In screen climbing, the software program is executed in a computer system and climbing is progressed by the interaction between a climber and the content of the screen. We implemented a screen climbing game with the ancient cave exploration considering the development of children and the children's motivation to sports climbing. The content of the game is projected to the artificial climb wall and the interaction between a user and the game is done by a user's input of Kinect's depth data. The game is popular with the children in the children's exhibition event. There should be implemented more screen climbing game.

Recently, screen climbing contents such as sports climbing learning program and screen climbing games. Especially, there are many researches on screen climbing games. In this paper, we propose the skeleton correction method based on the body area of a climber to improve the posture recognition accuracy. The correction method consists of the modified skeletal frame normalization with abnormal skeleton joint filtering, the classification of body area into joint parts, and the final skeleton joint correction. The skeletal information obtained by the proposed method can be used to compare the climber's posture and the ideal climbing posture.

Recently people have increased to climb mountain. Owing to developing IT technology, the number of people using smart phone have increased remarkably as well. In this context, the Korea Forest Service has implemented the project of Mountain Climbing Information Public Service(MCIPS). The purpose of the MCIPS is to support climbing safely based on a trail map of spatial data of GIS(geographic information system). The customer will be able to access the MCIPS through n-screen(IP-TV, Web Site, Smart phone, Galaxy tab) provided a broadcasting and telecommunication convergence service. In addition, the MCIPS would support two-way communication through connecting to Twitter and Youtube. The MCIPS will make the customer fun using Augmented Reality(AR) of Smart phone(Android) and contribute to protecting people from mountain accidents.

Physically interactive sport games are emerging as a solution to increase the physical activity of children in urban life. Existing studies on physically interactive sport games have been conducted with adults, while studies on children are insufficient. The elements of physically interactive sport games for children are derived from the common elements of physically interactive sport games and design for children. The derived elements are applied to actual game item to design a game for children. In this study, the elements of physically interactive sport games for children were applied to children's screen climbing games, and games could be identify improvements through user evaluation. It is expected games to take into consideration more children's characteristics can be designed by utilizing the elements of physically interactive sport games for children.

체감형 스포츠 게임은 신체활동이 부족한 어린이들의 활동량을 늘릴 수 있는 해결 방안으로 부상하고 있다. 기존 체감형 스포츠 게임관련 연구는 성인을 대상으로 한 연구들이 대부분이며 어린이를 대상으로 한 연구는 미흡한 실정이다. 제안하는 어린이 체감형 스포츠 게임 요소는 기존 성인대상의 체감형 스포츠 게임 요소들과 어린이 디자인 요소들의 공통 요소를 도출하고, 어린이에 맞춰 재해석한다. 도출된 요소는 적용해야 할 어린이 체감형 스포츠 게임에 맞춰 실제 요소를 도출하고, 실제 요소들을 고려하여 게임을 제작한다. 어린이 체감형 스포츠 게임 요소는 어린이를 대상으로 한 체감형 스포츠 게임 제작 및 평가 시 가이드라인으로 활용될 수 있을 것으로 기대된다.

Through the research on the design evaluation index of parent-child interactive game furniture, it is convenient for designers to quantitatively analyze the design advantages and disadvantages of related products, which is of positive help to control and improve the design quality. Combined with AHP and TOPSIS, this study proposes the evaluation model of three design criteria and 26 design indexes. After expert scoring, calculation, and consistency test of each index, the weight value of each design index is obtained, and the index is classified according to the importance of each index. Finally, eight essential indicators, eleven secondary indicators, and seven general indicators are classified. A case study was conducted with TOPSIS, and the design samples of three parent-child climbing game furniture were analyzed. Finally, the three samples' relative proximity was 0.505, 0281, and 0.640, respectively. The research shows that the AHP-TOPSIS method can scientifically and effectively sort and screen the advantages and disadvantages of design schemes and provide a reference for the research and development of related products.

This study was done to develop PDA based application system for forest geographic information with GPS. The major results obtained in this study were as follows. A PDA based application program was developed to work on $Microsoft^{TM}$ PocketPC 2002 and 2003 operating system. The screen of PDA displays a 1:25,000 digital topographical map adopted DXF format converted from PC, and the map data with 1:2,500 to 1:30,000 on PDA can be zoomed in or out to five levels. Current position and navigating path received from GPS can be displayed on the screen and be saved in PDA. Information selected among layers of digital topographic map in DXF format can be converted into binary files which can be used on forest geographic information software. This can compress DXF files to 90% in size, and the processing speed of PDA was improved. The forest geographic information management system can be used to manage sample plots on which forest inventory is done, with the help of the sub-menus and grid index values with position information received from GPS. Forest workers can in quire forest geographic information such as forest type, location, forest roads, soil erosion control dams using forest geographic information management system in the field. The forest geographic information management system can provide current position and mobile path information to people who enjoy forest related activities like mountain-climbing, sightseeing, and visiting to historic spots.
