Using the extended technology acceptance model (TAM), the study aimed to understand consumers’ adoption process for smart fashion products. The research model was designed to examine the impacts of perceived ease of use and usefulness on attitude and behavior intention toward smart fashion products based on the technology innovativeness, enjoyment, and subjective norm variables. An online survey was conducted on consumers by employing a marketing research company. A total of 230 useable responses were obtained. Confirmatory Factor Analysis (CFA) was performed to test the measurement model. The proposed hypotheses were tested by employing the Structural Equation Model (SEM). The results found a positive impact of perceived ease of use on usefulness and a positive influence of usefulness on attitude and behavior intention. Attitude had a positive effect on behavior intention. In addition, technology innovativeness was found to have a positive influence on perceived ease of use and enjoyment had a positive influence on usefulness and attitude. Subjective norm predicted behavior intention. The findings of the study contribute to smart fashion literature and have important implications for smart fashion product developers and marketers, as they offer insights into the important role of technology innovativeness, enjoyment, and subjective norms perceived by consumers in improving attitudes and behavior intentions toward the products. Limitations and future research directions are discussed.

ICT in the IOT era is the core basis of modern society. This study investigated and analyzed the recent commercialization trends of smart fashion products internationally and domestically, to utilize them as the basis of data for developing user-friendly smart fashion products that can meet the needs of consumers. Keyword research using the most representative search engines, Google and Naver was conducted for searching for various wearable items commercialized actively since 2010. The final 78 products were classified by the physical area, and the key features and benefits were analyzed. Smart fashion products were classified as four physical types for the head and face, torso, arms and hands, and ankles and feet. Smart fashion products for each body part were developed in various ways, such as hats, glasses, lenses, virtual screens, earphones, headsets, clothing, watches, wrist bands, gloves, rings, wallets, bags, anklets, shoes, socks, and insoles. The main features were music playback, bluetooth, a camera based on NFC, virtual effects, health and safety protection through measuring heartbeat and momentum, and social network sharing of all kinds of information, based on inter-working with a smartphone. These functions represent the physical, social, and emotional interactions among users and their surroundings, as well as the users, themselves. The research results are expected to be used in future studies on planning user-friendly and marketable products through in-depth analysis of the design characteristics of smart fashion products as well as consumer responses.

This study presents a flexible and highly stretchable textile circuit line for the signal and power transmission of smart clothing systems that provide wearing comfort and high mobility to where’s. A textile based circuit network on smart clothing requires 30% stretch ability so as not to constrain body movement. The advantages of a textile band type transmission line is the easy configuring of several separate transmission lines on a single band to construct a sensor module network. Conductive transmission line yarns have to be protected from deformation when textile transmission lines are stretched according to body movement. To ensure the elastic property of the smart clothing, textile transmission lines need to stretch more than 30% using the additional spandex yarns in warp. Four strands of conductive yarns were inserted in a single transmission line and each transmission line indicated 0.03Ω/cm in resistance. The resistance change rate of the textile transmission line during elongation was measured using a universal testing machine (Instron 5543) and Milliohmeter (Agilent 4338). The resistance of the transmission lines unchanged until breakage occurred at the 140% strain level. Resistance started to change at the 180% strain level where conductive yarns start to deform and break. In conclusion, the proposed textile transmission provides a comfortable wearing sensation that maintains a stable electrical performance during any type of body movement and is suitable for the wearable circuit of a highly stretchable smart wear system.

This study developed a user focused interface to improve a temperature regulation smart wear system controlled by a textile switch embedded on the outer surface. Designers need to investigate problems between design and consumers to enhance usability. Companies usually launch a final product where problems are resolved by repeated usability evaluation from the initial stage of product development. A textile switch was made all fabric for natural wear ability and designed for easy control and hands-free operation. Usability evaluation for textile switch design was conducted after reading manual without functioning. The survey selected five possibilities (metaphor, consistency, efficiency, flexibility, and aesthetic) from 10 heuristic evaluation assessment criteria of Nielsen(Feedback, metaphor, control, consistency, error prevention, efficiency, flexibility, aesthetic, recover form error, and help) to evaluate with a 5-point Likert-type rating scale restricted by 17 questions that collected specific opinions about user satisfaction. We randomly selected 20 general users to conduct the survey. A textile switch was made all fabric for natural wear ability and designed for easy control and hands-free operation.

We randomly selected 20 general users to conduct the survey. Textile switch is suitable for the interface of temperature regulation smart wear systems in terms of usability, because it synthetically presented high user satisfaction standards. We modify the final prototype based on usability problems selected through subjective evaluation.
