Abstract

In order to design and develop a ubiquitous game, it is necessary to develop a natural and flexible interface between the real world and the virtual world, based on social and physical context awareness. We design user interface model and the tactile sensing system that performs virtual interaction and collection of the sensor data. It is sensitive so the collected data should be filtered, rearranged and analyzed. This information is quite different from stylus input, keyboard, button or mouse for interaction. We detect kicked 3D force position of a ball, moment of area, moment of inertia and modified ball shape using tactile sensing system and analyzed data. The results demonstrate that the proposed approach is desirable and robust as well as the results can be used realistic actions and reactions considering attack force and to make interesting environments for ubiquitous game.

유비쿼터스게임을 디자인하고 개발하기 위하여 현실세계과 가상세계와의 자연스럽고 다양한 상호작용이 필요하다. 이는 물리적인측면 뿐 아니라 상황변화에 알맞은 대응 감지기술을 필요로한다. 이를 위하여 가상세계와의 유저인터페이스 모델을 정의하고 이를 구현하기 위하여 텍타일감지 시스템을 제작하였다. 텍타일 데이터는 외부환경에 민감하므로 신호처리방법을 사용하여 잡음을 제거하고 유저인터페이스를 위한 데이터 형태로 외부입력을 분석 추론하였다. 이는 일반적인 게임에서 사용하는 마우스나 키보드에 따른 입력과 전혀 다른 형태의 입력으로 유비쿼터스 환경에서의 플레이어의 상황대응에 대한 중요한 정보를 제공하여준다. 구현한 시스템을 통하여 가상공간상에 존재하는 공에 작용한 힘을 3차원적으로 분석하여 힘의 위치, 크기, 분포, 방향 등을 분석하는 방법을 제시 해보았으며 이 같은 실세계 정보 분석을 통하여 가상공간상에서 3차원적인 자연스러운 반작용이 가능하도록 하는 가능성을 보였다. 이 같은 방법들은 유비쿼터스 게임의 상호작용 개발을 위한 기초자료로 사용될 수 있다.
