Abstract

With the outbreak of COVID-19 a few years ago, video conferencing and electronic document work have increased, and for this reason, the proportion of computer work among modern people's daily routines is increasing. However, as more and more people work on computers in the wrong posture for a long time, the number of patients with poor eyesight and text neck is increasing. Until recently, many studies have been published to correct posture, but most of them have limitations that users may experience discomfort because they have to correct posture by wearing equipment. A posture correction sensor algorithm is proposed to prevent access to the minimum distance between a computer monitor and a person using an ultrasonic sensor device. At this time, an algorithm for minimizing false alarms among warning alarms that sound at the minimum distance is also proposed. Because the ultrasonic sensor device is used, posture correction can be performed without attaching a device to the body, and the user can relieve discomfort. In addition, experimental results showed that accuracy can be improved by reducing false alarms by removing more than half of the noise generated during distance measurement.

몇 년 전 코로나가 발병하면서 화상 회의, 전자 문서 작업이 많아지게 되었고 이 때문에 현대인들의 하루 일과 중에서 컴퓨터 작업을 하는 비중이 증가하고 있다. 하지만 오랜 시간 동안 잘못된 자세로 컴퓨터 작업을 하는 사람들이 많아지게 되면서 시력 저하, 거북목증후군 환자들이 늘고 있다. 최근까지도 자세 교정을 위한 연구들이 많이 발표되고 있지만 대부분은 사용자가 장비를 착용하여 자세 교정을 해야 하므로 사용자가 불편함을 겪을 수 있다는 한계가 있다. 본 논문에서는 초음파 센서 장치를 이용하여 컴퓨터 모니터와 사람 사이의 최소 거리 접근을 방지하기 위한 자세 교정 센서 시스템을 제안한다. 그리고 이때 최소 거리 시 울리는 경고 알람 중 오류 알람을 최소화하는 알고리즘도 함께 제안한다. 이는 초음파 센서 장치를 이용하기 때문에 몸에 기기를 부착하지 않고도 자세 교정을 할 수 있으며 사용자의 불편함을 해소할 수 있다는 장점이 있다. 또한, 실험 결과에서 거리 측정 시 발생한 잡음을 제거하여 오류 알람을 줄임으로써 정확도를 높일 수 있음을 보였다.
