최근 스마트 기기의 장시간 사용으로 인해 목, 허리, 어깨 등의 근욱의 통증을 호소하는 사용자들이 늘고 있다. 하지만, 기존 연구는 주로 데스탑, VDT에 관한 근골격계 피로 위주로 연구되어, 최근 사용이 급증하는 스마트 기기로 인한 근골격계 피로에 대한 이해에는 한계가 있다 본 연구에서는 사용자들의 스마트기기(휴대폰, 테블릿 PC)사용 자세를 비디오로 촬영하고, 각 신체부위별 부하 정도를 측정 하기 위해 동적 자세 프로그램을 이용하여, 관절각도(굴곡, 신전, 외전, 내적 각)를 분석하였다. 분석결과 핸드폰과 태블릿 pc 사용에 있어 목, 손목, 어깨, 팔꿈치 굴곡에 있어 유의한 차이가 있었으며, 사용자의 키, 하루 평균 사용시간, 회당 평균 사용시간에 다라 어깨, 팔꿈치 굴곡 등에서 유의한 차이가 있었다. 각 관절별 굴곡 수치를 토대로 군집 분석을 이용하여 5개의 주요 스마트기기 사용 자세를 식별하였다. 본 연구결과는 스마트기기 사용자 피로도 예측을 위한 기초연구로 활용 가능하다.

Developing an Affective Visual Quality Metric for Vehicle Door Trim
Wonjoon Kim,Soochan Jee,Taebeum Ryu,Myung Hwan Yun 대한인간공학회 2013 대한인간공학회 학술대회논문집 Vol.2013 No.10
Objective: The aim of this study is to determine the affective impressive that occurs when the driver see the door trim of the vehicle analyzing the relationship the design elements and affective quality perception. By examining the various impressive changes between when observing the vehicle door trim, a researcher can materialize the affective feeling and suggest design variable of door trim that can improve the affect goal. Background: Affective engineering is a method devised to measure and analyzes a person’s affectivity in diverse ways—which appears when using products. Method: The experiment was conducted with 7 vehicles, 30 subjects were collected in the process, and questionnaire composed of 7 and 100 point scales was prepared to perform evaluation on affectivity for luxuriousness of vehicle doors. Through performing regression analysis, the result of evaluation was utilized to create a model that can presume the luxuriousness of door appearance. Results: As a result of the regression analysis, harmonious, sophisticated turned out to be the affective adjectives that have impact on improving the luxuriousness of vehicle doors. It was possible to recognize that depending on the type of vehicles, different adjectives were used to describe luxuriousness. Moreover, door handle shape, seat adjust button were confirmed to be the design variables that influence the luxuriousness. Conclusion: Through quantitative and qualitative analysis on luxuriousness of vehicle doors, we expect that a luxuriousness model of vehicle doors can be developed based on design variable and affective adjective of vehicle doors—to further aid the designing procedure of vehicle doors for improving luxuriousness. Application: With the results of this study, designer of vehicle door trim is able to know how to make the design variables of door trim for the desired level of luxuriousness. And we’ll be able to expect that customers’ perception of luxuriousness for vehicle door trim can be conceptualized more clearly.

Recently kansei-engineering approach on various products and feedback has been carried out, affective response on haptic modality also has gained greater attention. The aim of this study is to analyze the effect of mode of haptic on affective response. In order to analyze the perception characteristics according to haptic mode, the experiments with jog dial were divided into active < haptic > where the participants were directly involved with controlling devices and into passive < haptic > where the participants remained uninvolved. 9 haptic feedbacks represented by specific sine wave having width, magnitude, detent type, and detent width were provided to users utilizing simulator devices. Six affective variables, perspicuity, smoothness, heaviness, elasticity, liltingness, and satisfaction, were evaluated by 25 subjects. Averages of affective elements in each mode were compared and change pattern according to haptic feedback parameter was investigated through statistical analysis. As a result, perspicuity, heaviness and elasticity were perceived larger when the mode was set to active haptic, while smoothness was perceived larger in passive haptic, and perspicuity and heaviness have shown significant difference according to haptic mode (α<0.05). Experiment result shows that the affective elements related with difference of force are largely evaluated in active haptic than in passive haptic and assessment according to magnitude of stimuli was not consistent in passive haptic. This study shows that haptic stimuli should be larger than intended to provide intended feedback to user under context of virtual reality using passive haptic mode.
