초록

제스처는 빠르고 간편하게 명령을 수행 할 수 있어서 스마트폰과 태블릿PC, 웹브라우저를 비롯한 수많은 어플리케이션에서 사용되고 있다. 어플리케이션에 제스처를 적용하기 위해서는 제스처를 디자인해야하는데 사용자와 시스템 두 가지 측면을 모두 고려하여 디자인해야 한다. 이러한 제스처 디자인을 도와주고자 몇몇 툴들이 개발되어왔다. 그럼에도 불구하고 제스처를 디자인하기 위해서는 다음과 같은 어려움이 남아있다. 첫째, 모든 제스처를 사람이 직접 디자인해야 한다. 둘째, 디자인한 제스처를 인식기가 올바르게 인식할 수 있도록 반복적인 트레이닝 작업을 해야 한다. 본 논문에서는 보다 간편한 제스처 디자인 환경을 제공해 주고자 자동화 트레이닝, 제스처 제안, 제스처 생성을 제안하였다. 이를 통해 제스처를 트레이닝 시킬 필요가 없어졌고 생성된 제스처와 수집된 제스처의 마할라노비스 거리를 계산하여 이 중 인식이 잘 될 가능성이 높은 순서대로 제스처들을 제안해 줌으로서 모든 제스처를 직접 디자인해야 하는 노력을 줄일 수 있게 되었다.

Gesture is applied in many applications such as smart-phone, tablet-PC, and web-browser since it is a fast and simple way to invoke commands. For gesture applications, a gesture designer needs to consider both user and system during designing gestures. In spite of development of gesture design tools, some difficulties for gesture design still remains as followings; first, a designer must design every gesture manually one by one, and, second, a designer must repeatedly train gestures. In this paper, we propose a gesture proposal system that automates gesture training and gesture generation to provide more simple gesture design environment. Using automation of gesture training, a designer does not need to manually train gestures. Proposed gesture proposal system would decrease difficulties of gesture design by suggesting gestures of high recognition possibility that are generated based on mahalanobis distance calculation among generated and pre-existing gestures.
