Abstract

Recently, smart wearable devices for monitoring health status have been utilized as interest in health care has increased. In this paper, we developed a fatigue measurement system that works with smart wearable devices. Unlike physical fatigue that is restored when you take enough rest, mental fatigue can decrease the efficiency or concentration of work, so you can monitor your mental health status through measurements. This system provides the function to transmit the measured data from the smart wearable device to the smartphone and to calculate the mental fatigue. A fatigue index was developed to measure fatigue and expressed as a number from 1 to 5. In addition, the results of the fatigue calculation and the survey were compared with the results of the independent sample t-test. Therefore, this system will be used to help users manage their health efficiently.

최근 건강관리에 대한 관심이 높아지면서 건강상태를 모니터링 하기 위한 스마트 웨어러블 디바이스가 활용되어 오고 있다. 본 논문에서는 스마트 웨어러블 디바이스와 연동된 피로도 측정 시스템을 개발하였다. 충분히 휴식을 취하면 회복되는 신체적인 피로도와는 달리 정신적인 피로도는 일의 능률이나 집중력을 떨어트릴 수 있으므로 측정을 통해 정신 건강 상태를 모니터링 할 수 있다. 본 시스템은 스마트 웨어러블 디바이스에서 계측한 데이터를 스마트폰으로 전송하고 정신적인 피로도를 계산해주는 기능을 제공한다. 피로도를 측정하기 위한 피로도 인덱스를 개발하여 1부터 5까지의 수치로 표현하였다. 또한 피로도 계산 결과와 설문조사 결과와 비교하여 독립표본 t-검정을 실시한 결과 통계적으로 유의한 값이 나왔다. 본 시스템은 사용자들이 건강을 효율적으로 관리하는 데에 활용될 것이다.
