Abstract

In this paper, we categorize existing human gesture recognition technologies to camera-based, additional hardware-based and frequency-based technologies. Then we describe several representative techniques for each of them, emphasizing their strengths and weaknesses. We define important performance issues for human gesture recognition technologies and analyze recent technologies according to the performance issues. Our analyses show that camera-based technologies are easy to use and have high accuracy, but they have limitations on recognition ranges and need additional costs for their devices. Additional hardware-based technologies are not limited by recognition ranges and not affected by light or noise, but they have the disadvantage that human must wear or carry additional devices and need additional costs for their devices. Finally, frequency-based technologies are not limited by recognition ranges, and they do not need additional devices. However, they have not commercialized yet, and their accuracies can be deteriorated by other frequencies and signals.

본 논문에서 우리는 인간 동작 인식 기술을 카메라 기반, 추가적인 하드웨어 기반, 그리고 주파수 기반 기술들로 분류한다. 각 기술 항목에 대한 대표적인 기술사례들을 설명하고, 그들의 장점과 단점을 기술한다. 인간 동작 인식 기술에 대한 중요한 성능 이슈 항목을 정의하고, 소개된 인간 동작 인식 기술들을 정의된 성능 이슈 항목에 따라 분석한다. 분석 결과 카메라 기반 인간 동작 인식 기술들은 공통적으로 손쉽게 사용할 수 있고, 높은 정확도로 동작을 인식할 수 있지만, 비용적, 인지 범위 등의 단점이 있다. 이에 비해 추가 하드웨어 기반 동작 인식 기술들은 공간의 제약, 빛이나 소음 등의 영향을 받지 않거나 최소화하였지만, 사용자가 직접 착용을 해야 하는 단점을 가진다. 최근에는 이러한 문제점을 보완하고자 주파수 기반 동작 인식 기술들이 연구 및 개발 중에 있다. 이들은 공간의 제약을 줄이고, 추가적 장비 없이 쉽게 동작인식을 할 수 있지만 아직 상용화 되지 않은 초기 연구 단계이며, 다른 신호나 주파수가 정확도에 영향을 줄 수 있다는 단점이 있다.
