LED 글러브를 사용한 손 제스처 인식과 확장된 사용자 인터페이스 = Hand Gesture Recognition and Expanded User Interface Using LED-Glove

다국어 초록 (Multilingual Abstract)

In the well-known movie, "Minority Report", Tom Cruise, the main character, extracts information from the memories of prophets using LED-based hand gestures. The hand-worn glove device and the gesture interface used in the movie seemed very convincing and plausible. Motivated by the ideas of the movie, we devised and developed gesture and posture based user interface that may help people communicate with each other in collaborative visual environments.
Gestures and postures have been popular research topics for hand-free interface in Human-Computer Interaction (HCI) areas. However, gesture spotting (distinguishing pure gestures from garbage gestures) is not an easy process, making gesture recognition impractical. For this reason, most of the previous systems are not accurate enough to be used as a practical interface tool. To solve the gesture spotting problem, we used LED switches to turn on and off between the start and the end point of a gesture. Segmented gestures were recognized using a Hidden Markov Model (HMM) after learning processes. We also used 3-point LED postures to implement mouse click and double click interfaces in order to replace mouse functionalities.
