This study aimed to develop a modular smart clothing system for heart rate monitoring that reduces the inconvenience caused by battery charging and the large size of measurement devices. The heart rate monitoring system was modularized into a temporary device and a continuous device to enable heart rate monitoring depending on the requirement. The temporary device with near-field communication (NFC) and heart rate sensors was developed as a clothing attachment type that enables heart rate monitoring via smart phone tagging when required. The continuous device is based on Bluetooth Low Energy (BLE) communication and batteries and was developed to enable continuous heart rate measurement via a direct connection to the temporary device. Furthermore, the temporary device was configured to connect with a textile electrode made of a silver-based knitted fabric designed to be located below the pectoralis major muscle for heart rate measurement. Considering the user-experience factors, key functions, and the ease of use, we developed an application to automatically log through smart phone tagging to improve usability. To evaluate the accuracy of the heart rate measurement, we recorded the heart rate of 10 healthy male subjects with a modular smart clothing system and compared the results with the heart rate values measured by the Polar RS800. Consequently, the average heart rate value measured by the temporary system was 85.37, while that measured by the reference device was 87.03, corresponding to an accuracy of 96.73%. No significant difference was found in comparison with the reference device (T value = -1.892, p = .091). Similarly, the average heart rate measured by the continuous system was 86.00, while that measured by the reference device was 86.97, corresponding to an accuracy of 97.16%. No significant difference was found in terms of the heart rate value between the two signals (T value = 1.089, p = .304). The significance of this study is to develop and validate a modular clothing system that can measure heart rates according to the purpose of the user. The developed modular smart clothing system for heart rate monitoring enables dual product planning by reducing the price increase due to unnecessary functions. 본 연구의 목적은 심박 측정용 기기 및 의류에 있어 배터리 충전 및 기기의 부피감으로 인한 불편함을 개선하고, 사용자 편의성을 고려하여 목적에 따른 심박 측정을 가능케 하는 심박 측정용 스마트 의류 시스템을 개발하고자 하였다.심박 측정 기기는 2가지 타입으로 모듈화되어 개발되었으며, 탈부착을 통해 목적형 및 지속적 심박 측정이 가능하도록 구성하였다. 목적형 심박측정 기기는 NFC(Near Field Communication), 심박 센서를 내장하고 필요시에 스마트 폰 태깅을 통해 심박 측정이 가능하게 하는 의류에 부착된 타입으로 개발되었으며, 지속형 심박 측정 기기는 BLE(Bluetooth Low Energy) 통신 및 배터리를 내장하여 목적형 기기와 결합을 통해 통신 및 전원을 지원, 지속적으로 심박 측정이 가능한 시스템으로 구성되었다. 심박 측정을 위한 섬유 전극은 은사 기반의 편물 전극으로, 심박 측정에 용이하도록 대흉근 아래에 위치하도록 디자인되었으며, 목적형 심박측정 기기가 전극과 연결되도록 구성되었다. 연동 되는 어플리케이션은 사용자 경험요소, 주요기능 및 사용편의성 등을 고려하여 개발되었으며, 사용성 향상을 위하여 스마트 폰 태깅을 통해 자동 동기화가 되도록 개발되었다. 본 연구에서 개발된 심박측정 스마트 의류 시스템의 심박측정 정확도를 평가하기 위하여, 10명의 20대 남성 피험자를 대상으로 2단계의 실험을 설계하고 진행하였으며, POLAR RS800을 통해 측정되는 신호를 기준 심박으로 비교·분석하였다. 그 결과, 목적형 스마트 의류 시스템의 평균 심박수는 85.37, 기준 기기 심박수는 87.03으로 96.73%의 정확도를 갖는 것으로 분석되었으며, T 값 –1.892 (p=.091)로 두 신호간의 유의한 차이는 없는 것으로 분석되었다. 지속형 스마트 의류 시스템의 평균 심박수는 86.00, 기준 기기 심박수 는 86.97로 97.16%의 정확도를 보였으며, T 값 –1.089(p=0.304)로 두 시스템 간의 측정 차이는 없는 것으로 분석되었다. 본 연구에서는 사용자의 목적에 따라 심박측정이 가능한 모듈형 스마트 의류 시스템을 개발하고 검증한 것에 의의가 있다. 또한, 모듈화 된 심박측정 의류 시스템 개발로 불필요한 기능으로 인한 가격 상승을 줄임으로써 이원화된 상품 기획의 가능성을 제시하였다.

This study examines the impact of live commerce characteristics on customer responses in the ELM per- spective. Based on ELM, the central route is composed of information completeness, accuracy, and currency, and the peripheral route is composed of streamer credibility, streamer reputation, social presence, and system quality. An online survey of female customers aged 20 to 49 who have purchased beauty products through live commerce within the past three months was conducted. The results demonstrate that information completeness and information currency exert significant impact on perceived usefulness and enjoyment. Social presence and system quality also exert significant impact on perceived usefulness and enjoyment. Moreover, perceived use- fulness and enjoyment had significant impact on behavioral intention. The effect of information completeness on perceived usefulness and enjoyment was much stronger for high product involvement groups. Furthermore, the effect of streamer reputation on perceived enjoyment was much stronger for high product involvement groups. In contrast, the effect of social presence on perceived usefulness and enjoyment was much stronger for low product involvement groups. This study suggests theoretical implications for applying ELM to live com- merce and practical implications for differentiated live commerce marketing strategies.

조하경 ( Ha Kyung Cho ),조상우 ( Sang Woo Cho ) 한국감성과학회 2015 감성과학 Vol.18 No.3

최근 고기능성 제품에 대한 수요가 증가함에 따라 ICT 기능과의 융합을 통한 스마트 의류는 일상생활 분야로 확대되고 있다. 그 중 하나로, 발열 텍스타일 및 제어 모듈을 통해 의복 내 발열기능을 조절하는 스마트 의류에 대한 관심이 높아지고 있으며, 발열 기능을 갖는 스마트 의류의 시장 전망이 높아지고 있으나, 발열 패드 부착위치에 따른 발열 기능의 효용성 및 온열감에 대한 연구는 부족한 실정이다. 본 연구에서는 발열 패드의 위치에 따른 피부온의 변화와 온열감에 대한 실증적 연구를 통하여 발열기능의 스마트 의류 개발을 위한 최적의 발열 위치를 도출하고자 하였다. 이를 위하여 20대 표준체형의 남성 10명을 피험자로 선정하였으며, 영하 5 ℃의 인공기 후실에서 20분의 안정기, 20분의 처치기, 40분의 회복기를 통해 11군데에서의 피부온, 직장온과 주관적 온열감을 측정, 평가하였다. 최종적으로, 발열패드를 위한 최적의 위치를 도출하고 제시하였다. In accordance with escalating demands for advanced technology products, the smart clothing that includes embedded ICT technology have expanded into fields of daily life. As a result of this trend, interest in smart clothing with digitally controllable heating has rapidly grown and the market for smart heated clothing has also expanded. Increasing of prospect in smart heated clothing market, the effectiveness and thermal sensation research of the location on the pad attached is insufficient. This study was conducted to find the optimal location of heated clothing via experimental research on changes in skin temperature and subjective thermal sensation when heating pads were placed on different areas of the body. For this experiment, the subjects consisted of 10 males in their 20’s of standard physique. The skin temperature at 11 different areas of the body, rectal temperature, and subjective thermal sensation were taken at different stages (before testing, after a 20 minute rest period, 20 minute treatment period, and after a 40 minute recovery period) in an artificial-climate chamber at .5 °C. As a result, the optimal location for heating pads in smart clothing was estimated and suggested.

The increase in the need for a 24 hour monitoring of biological signals has been accompanied by an increasing interest in wearable systems that can register ECG at any time and place. ECG-monitoring clothing is a wearable system that records heart function continuously, but there have been difficulties in making accurate measurements due to motion artifacts. Although various factors may cause noise in measurements due to motion, the variations in the body surface and clothing during movements that cause eventual the shifting and displacement of the electrodes is particularly noteworthy. Therefore, this study used biomedical body mapping and a motion-capture system to measure and analyze the changes in the body surface and garment during movements. It was deduced that the area where the friction and separation between the garment and skin is the lowest would be the appropriate location to place the ECG electrodes. For this study, 5 male and 5 female in their 20s were selected as subjects, and through their selected body movements, the changes in the garment and skin were analyzed using the motion-capture system. As a result, the area below the chest circumference and the area below the shoulder blades were proposed as the optimal location of electrode for ECG monitoring.
