Abstract

In this paper, we developed the device for an interactive game interface using bio signals which were able to recognize user's motion intention using EMG signals and it was applied to the games which need the information of the muscle motion directions. The module for acquiring EMG signals consists of 4-Ch, wrist-motions were defined as up, right, down and left state. The user's intent was recognized through thresholding and comparing signals of each channel. The classification result of the motion directions could control the arrow keys on the keyboard of PC and it was applied on the various games. This proposed game device can be expected to induce an effective exercise with an interesting and enjoyment, and it can use both self-developed or commercial games.

본 논문에서는 생체 신호를 이용하는 체감형 게임 인터페이스 개발을 위하여 근전도 신호로부터 사용자의 동작 의도를 실시간으로 인식할 수 있는 장치를 개발하여 방향성을 필요로 하는 게임에 적용하였다. 근전도 신호를 획득하기 위한 장치는 4 채널로 이루어지며, 정의되는 손목동작으로는 Up, Right, Down, Left로 규정하였다. 각각의 동작으로부터 획득한 신호를 문턱치와 채널 간의 비교를 통하여 사용자의 의도를 인식하게 하였다. 방향성 분류 결과를 통하여 키보드의 방향키를 제어하고, 게임에 적용하게 된다. 개발된 장치는 재미와 흥미를 유도하여 효과적인 운동을 기대할 수 있으며, 상용화된 게임에도 적용할 수 있다.
