Wearable devices come in a variety of shapes and sizes in numerous fields in numerous fields and are available in various forms. They can be integrated into clothing, gloves, hats, glasses, and bags and used in healthcare, the medical field, and machine interfaces. These devices keep track individuals' biological and behavioral data to help with health communication and are often used for injury prevention. Those with hearing loss or impaired vision find it more difficult to recognize an approaching person or object; these sensing devices are particularly useful for such individuals, as they assist them with injury prevention by alerting them to the presence of people or objects in their immediate vicinity. Despite these obvious preventive benefits to developing Internet of Things based devices for the disabled, the development of these devices has been sluggish thus far. In particular, when compared with people without disabilities, people with hearing impairment have a much higher probability of averting danger when they are able to notice it in advance. However, research and development remain severely underfunded. In this study, we incorporated a wearable detection system, which uses an infrared proximity sensor, into a backpack. This system helps its users recognize when someone is approaching from behind through visual and tactile notification, even if they have difficulty hearing or seeing the objects in their surroundings. Furthermore, this backpack could help prevent accidents for all users, particularly those with visual or hearing impairments.

최근 생체 신호 센싱 기능의 의류가 연구 개발되어 왔으나, 생체 신호 측정 시 착용자의 동작에 의한 치명적인 잡음이 발생하는 문제가 지속적으로 보고되어 왔다. 이에 본 연구는 심전도 센싱 의류를 기반으로 생체 신호 측정의 정확성을 향상시키기 위하여 착용자의 동작에 의한 영향을 최소화할 수 있는 심전도 센싱 스마트 의류의 모형을 개발하고자 하였다. '일자형 절개 타입', '십자형 절개 타입', '엑스형 절개 타입', '곡선 엑스형 절개 타입'의 총 네 가지 타입의 생체신호 센싱 스마트 의류의 시안을 설계하고 제작하였다. 디자인 시안은 민소매 형태의 남성용 티셔츠로 신축성 있는 소재를 사용하여 인체 굴곡을 따라 의복과 전극이 밀착될 수 있도록 하였으며, 트랜스미터를 이용하여 메인 컴퓨터로 데이터가 무선 전송되게 하였다. 본 연구에서는 개발된 4 가지 의류 타임을 기반으로 인체의 정지 및 동작 상태에서의 심전도 센싱 성능을 평가하기 위해 동작에 따른 전극의 변위를 측정하고, 심전도 측정 평가를 실시하여 SNR을 분석하였다. 본 실험 곁과를 반영하여 의류 디자인 시안의 수정 및 보완 과정을 거친 후, 최종적으로 동작 잡음을 최소화하는 생체신호 센싱 스마트 의류 디자인 모형을 제시하였다.

Lots of interdisciplinary studies for fusion of high technologes and the other areas of research had been tried in these days. In sports training area, high technologies like a vital sign sensor or an accelerometer were adopted as training tools to improve the performance of the sports players. The purpose of this study is finding the proper locations on the human body for attaching the motion sensors in order to develop a smart sportswear which could be helpful in training players. The rowing was selected as a subject sport as lots of movements of the joint on human body could be seen in rowing motions. The players of rowing could be devided into two weight divisions, the lightweight and the heavyweight. In this study, the change rates of distance between markers on human skin as the players moved were took on the back, the elbow, the hip and the knee area on human body by 3D motion capturing system. The distances between markers and the differences between the lightweight and heavyweight were analyzed. Finally, this study provided the guide lines for designing a motion sensing smart sportswear.
