In this paper, we propose an escape game enhancing interaction between a user and game objects. Considering that the user can play fun with many interactive game objects, the proposed game allows the user to manipulate most of game objects in the game regardless of the game quest. In order for the user to easily manipulate the game object, the proposed game utilizes simple operation keys, and show the available game objects in the top part of the main screen. For fun and immersion in the game, the proposed game provides interactions similar to the reality.

본 논문은 디스플레이 장치에 출력된 가상 객체를 일상생활에서 사용하는 손동작을 사용하여 제어하는 것을 목표로 한다. 가상 객체를 제어하기 위한 기존의 많은 방법들은 사용자의 손동작이 아닌 포즈를 이용하기 때문에 직관적이지 못하고 포즈와 객체 제어 명령과의 관계를 미리 학습해야하는 단점이 있었다. 본 논문에서는 스테레오 카메라를 사용하여 사용자의 손과 손끝의 3차원 정보를 추출하여 3차원 공간에서 객체를 제어할 수 있도록 한다. 또한 사용자의 손동작을 인터페이스로써 정의하고 실시간으로 입력되는 사용자 손동작 입력 열을 검출하고 이를 동적시간왜곡 방법으로 분류하는 방법을 제안한다. 마지막으로 다양한 제스처와 여러 사용자에 대한 실험을 통하여 본 논문에서 제안하는 방법의 효용성을 확인한다.

In this paper, we purpose to manipulate virtual objects in three-dimension space by using hand gestures that are used in daily life. Previous methods to manipulate objects are not intuitive, because there are used hand pose instead of gesture. And the methods have a disadvantage to previously learn commands about relationship between pose and control. In this paper, we extract 3D information of hand and fingertips using stereo camera and enable to manipulate objects in 3D space. Also we define user interfaces using hand gestures. And we propose a method that is classification of sequences of hand gesture using dynamic time warping algorithm in real time. Finally, we certify usefulness and effectiveness of a proposed method as experiences with various users and gestures.

This paper presents a method for interactive virtual manipulation of a real object using camera tracking. Our method uses a predefined 3D model of a target object for tracking and rendering. A camera pose relative to the target object is estimated using 3D model-based tracking. A texture map is extracted from the image, which the 3D model is projected with the estimated camera pose. Then a texture-mapped model is rendered with manipulations by user inputs. Experimental results demonstrate that our method provides user interactions with 3D real objects on real scenes, not augmented virtual contents.

The aim of this study is to investigate the relationship between the object ability, basic movement ability, and mathematical ability of young children. Next, through this study, the influence of young children’s object manipulation ability and basic movement ability on mathematical ability was investigated. The subjects of this study were 80 children aged 5 years old. As a research tool, the non-mobile movement and mobile movement, the basic movement development test scale, and the young children’s picture-mathematical ability test scale were used. This survey was conducted from October 2018 to January 2019. For data analysis, correlation analysis and hierarchical multiple regression analysis were performed using the spss program. As a result of the study, it was found that there was a significant positive correlation between the non-mobile ability, movement ability, object manipulation ability and mathematical ability of young children. It was found that young children’s ability to manipulate objects and non-movement abilities had positive effect on their mathematical abilities. The movement ability of young children had both negative and positive effects on mathematical ability, but it was not found to be statistically significant. This study is meaningful in that it investigated the effects of non-mobile movement, mobile movement ability, and object manipulation ability, which are sub-capabilities of basic movement ability, which had not been investigated so far, on the mathematical ability of young children.

The purpose of this study to discover what effect the mathematics education program linked to outdoor movement activities have on the ability to manipulate objects. The subject of study was a kindergarten class. The experimental and comparative groups consisted of 20 people each. In order to verify the effect of applying the early childhood mathematics education program in connection with outdoor movement activities, a total of 15 weeks of program was conducted for young children. As a result of conducting this study, it was found that a mathematics education program linked to outdoor movement activities improves the ability to manipulate objects. The discussion based on the results of this study is as follows. First, we suggest to specific activities that can be performed in an outdoor environment should be developed and applied to the field of early childhood education. Second, we suggest that It is necessary to program various subjects that link to outdoor movement activities. Third, we suggest what various measures are needed to improve the young children's ability to manipulate objects.
