Abstract

Recently there has been an increasing interest on tangible games in which human motions are recognized rather than the handling of keyboards and mouses. Such games require a motion controller for recognizing the motions of users. In this paper, we analyze the characteristics of values of accelerator sensors which are generated by a user who perform a tennis swing while holding a smartphone with his/her hand, and propose a method for motion recognition based on DWT(Discrete Wavelet Transform). The proposed method enables a smartphone to serve as a motion controller, so that a user can enjoy a tangible tennis game without eliminates a need for buying the device. We developed a tennis game prototype using the proposed method. To our experiment, our method showed a high recognition rate and the usefulness in the game.

최근 키보드나 마우스 조작이 아닌 사용자의 모션을 인식하여 플레이를 진행하는 체감형 게임에 대한 관심이 증대하고 있다. 일반적으로 이런 게임을 위해서는 사용자 모션을 감지하는 모션 콘트롤러가 필요하다. 본 논문에서는 사용자가 스마트폰을 손에 쥔 채 5가지 타입의 테니스 스윙을 할 때 발생하는 가속도 센서 값의 특징을 분석하고, DWT(Discrete Wavelet Transform) 기반의 테니스 모션 인식 방법을 제안한다. 우리의 방법은 스마트폰이 모션 콘트롤러 역할을 할 수 있게 함으로써, 사용자는 별도의 모션 콘트롤러를 구입할 필요 없이 손쉽게 체감형 테니스 게임을 즐길 수는 장점이 있다. 제안된 방법을 기반으로 테니스 게임 프로토타입을 개발하여 실험한 결과, 제안된 방법은 테니스 게임 진행에 충분히 높은 인식률을 보여 컴퓨터 게임에서 유용함을 확인하였다.
