초록

발표자료를 표시하는 프로그램 제어용 도구인 프레젠테이션 리모트 컨트롤러(presentation remote controller)를 발전시켜 단순한 페이지별 이동기능 외에 발표자의 긴장도를 실시간으로 확인하고 인체 반응 상태를 점검하며, 발표능력과 전달의도가 정확하지 못한 부분을 미리 확인하고 보완할 수 있는 지능 부가형 제어기 구성을 제안하고 성능을 시험한다. 제어기로는 스마트 폰이 사용되며 블루투스(bluetooth) 모듈을 인터페이스로 하여, 실행되는 프로세서에 접속하고 맥박 신호를 발표자 신체신호로 검출하여 실시간(150 ms 이내)으로 인체 상태를 인식하고 기록한다. 저장된 인체신호 데이터는 가공/처리되어 발표 능력과 자신감 향상의 자료로 이용한다. 이러한 일련의 과정은 4년제 대학의 졸업예정자를 대상으로 20주의 비정규적인 캡스톤디자인 활동을 통해 이루어진 결과이다.

In this study, the new model of presentation remote controller in which has improved the conventional function and deteceted the level of human's tension on a real time basis is suggested and tested. Existing presentation remote controller was just used turning the pages. But new model controls presentation and check tension level on real time using the smart phone's bluetooth interface. The proposed system is comprised with the PPG (Photo-Plethysmo-Graphy) sensor, Bluetooth and Wi-Fi modules. The configured system is to process (within 150 ms) the pulse signals of the presenter and stored the data. As a result, it can check and make up for the week presentation part and used as sources for improving self-confidence. This is the result obtained from the process of capstone design irregular course for 20 weeks of a graduate-to-be in four-year college.
