최근 스마트폰을 이용한 사용자의 운동량 계산 어플리케이션이 많이 출시되고 있다. 이러한 어플리케이션은 스마트폰의 GPS, 가속도 등의 내장 센서들을 이용하여 사용자의 행위를 분석하고, 분석된 내용을 토대로 운동량을 단순 계산해 주는 것들이 많다. 이러한 단순 계산은 사용자의 행동을 지정된 행동으로 인식하여 계산하기 때문에 복잡한 운동을 할 경우 어플리케이션에서 측정하는 칼로리 소모량과 실제 칼로리 소모량 계산과 비교해보면 오차가 많이 나는 경우가 많다. 이러한 오차를 줄이고자 신발에 압전센서와 블루투스 통신을 포함한 모듈을 삽입하여 사용자의 이동거리와 발걸음 수를 정확히 측정하여 사용자의 운동을 인식하고, 측정된 데이터를 이용하여 운동이 끝난 뒤 발걸음수와 이동거리를 이용하여 사용자의 소모된 칼로리를 정확하게 측정할 수 있는 방법을 제시하였다.

본 논문에서는 사람의 걸음걸이 분석을 위한 소형 웨어러블 시스템을 개발한다. 신발 내 깔창에 부착 가능한 소형화된 모듈을 설계하고, 압력 센서 및 가속도 센서를 이용하여 사용자의 걸음걸이에 대한 정보를 측정하고 측정 데이터를 바탕으로 사용자의 자세를 분석한다. 분석한 결과는 블루투스 통신을 이용하여 사용자의 스마트폰으로 전송이 가능하고, 사용자는 자신의 걸음걸이에 대한 정보를 실시간으로 확인하여 스스로 자세교정을 할 수 있도록 유도한다.

Smart Factory is different from existing factory automation in that it aims to produce personalized products with minimum time and cost through ICT. However, previous researches, not from consumers but from product suppliers, have focused on technology trends and technology application methods. In order for Smart Factory to be successful, it must go beyond supplier-focus to meet the needs of consumers. In this study, we surveyed the purchase intention of the personalized product manufactured by smart factory. Influencing factors of purchase intention were drawn as consumers' need for uniqueness, innovativeness, need for touch, and privacy concern, based on previous research. As results of data analysis, it was confirmed that respondents were willing to purchase personalized products, and that consumers' need for uniqueness, innovativeness, and need for touch had a significant impact on purchase intention of personalized products. Our findings can be summarized as follows. First, Consumers' need for uniqueness was found to have positive effects(${\beta}=0.168$) on purchase intention of personalized products. The desire to differentiate themselves from others will be reflected in their personalized products. Therefore, consumers with a higher desire for uniqueness tend to be more willing to purchase personalized products. Second, consumer innovativeness was found to have positive effects(${\beta}=0.233$) on purchase intention of personalized products. Personalized shoes suggested in this study is a new type of personalized product that is manufactured by the latest information and communication technologies such as multi-function robots and 3D printing. Therefore, consumers seeking innovative new experiences are more willing to purchase personalized products. Third, need for touch was found to have positive effects(${\beta}=0.299$) on purchase intention of personalized products. In a smart factory environment, prosuming participation is given to consumers. If consumers participate in the product development process and reflect their requirements on the product, they are expected to increase their purchase intention by virtually satisfying the need for touch. Fourth, privacy concern was found to have no significantly related to purchase intention of personalized products. This is interpreted as a willingness to tolerate the risk of exposing personal information such as home address, telephone number, body size, and preference for consumers who feel highly useful in personalized products.

Gait analysis trackers have been developed to monitor daily gait patterns to improve users' running performance and reduce the risk of injuries. A variety of gait analysis trackers are available on the market(e.g., foot pods, insoles). Depending on the type of gait analysis tracker, users' discomfort or satisfaction as well as required properties may differ. Hence, the purpose of this study was to compare and analyze user experience of three different types of commercial shoe-mounted gait analysis trackers and their mobile applications in a laboratory environment using questionnaires based on actual experiences of each product. Ten males and ten females who regularly enjoy walking and running exercises participated in the experiment. After the participants set up the tracker and application themselves without support from researchers, ten to thirty minutes' exercise was permitted on each product. Following this, the participants answered questionnaires containing evaluation variables on the device and mobile application, as well as satisfaction, intention to use, recommendation, and purchase. In addition, they were asked questions about the attractive features and shortcomings of each device and application. The results showed that the PRO-SPECS^® smart insole was preferred over the others for ease of use, perceived durability, psychological burden of the design, and usefulness of the information provided by the application. Along with the results of questionnaire, this study also discussed strategies and recommendations for future product design and development.
