Emerging smart textiles have enriched a variety of wearable technologies, including fiber optic technology. Optic fibers are widely applied in communication, sensing, and healthcare, and smart textiles enable fiber optic technology to be worn close to soft and curved human body parts for personalized functions. This review briefly introduces wearable fiber optic applications with various functions, including fashion and esthetics, vital signal monitoring, and disease treatment. The main working principles of side emission, wavelength modulation, and intensity modulation are summarized. In addition, textile fabrication techniques, including weaving and knitting, are discussed and illustrated as combination methods of embedding fiber optic technology into textile fabric. In conclusion, the combination of optical fibers and textiles has drawn considerable interest and developed rapidly. This work provides an overview of textile-based wearable fiber optic technology and discusses potential textile fabrication techniques for further improvement of wearable fiber optic applications.

Miao silver, generally referred to as the unique silver ornaments manufactured by the Miao ethnicity with over 400 years of history, was listed as a Chinese national intangible cultural heritage in 2006. Through primary research methods, including local investigation, interviews, and workshops at Maliao Village in Guizhou, this study found that sizeable industrial production shrank the market needs for traditional Miao silver handicrafts. A growing number of young Miao people pursue higher incomes and leave their hometowns to make a living in cities instead of engaging in Miao silver handcrafting in villages. Based on the difficulties encountered in the inheritance of Miao silver craftsmanship, this project creatively proposed a digital strategy based on the NFT digital twin application to preserve and maintain Miao silver technology in the context of the metaverse era. By conducting design experiments combining digital technology and the traditional Miao silver manufacturing techniques, a collection of NFT digital twins, digital duplications of Miao silver handicrafts that Miao silversmith jointly worked with 3D technologist, was created as a vital research outcome. The results show that this attempt is beneficial to help expand the use scenarios, extend the lifespan, and increase the commercial value of Miao silver. To sum up, taking Miao silverware handicrafts as a research case, this paper dialectically discusses the relationship between industrial manufacturing and traditional handicraft industries, making contributions to the inheritance and development of Miao silver and also putting forward innovative solutions to promote the prosperity of intangible cultural heritage worldwide.

Sustainability studies in tourism are increasingly emphasizing social matters, for instance, “Accessible Tourism for All.” Research on people with visual impairments with smart tourism has so far been sparse. In order to resonate with the global call for sustainable tourism development, this paper aims to contribute to understanding the aspirations of people with visual impairments in terms of tourism and to explore how smart tourism destinations could potentially enhance the tourism experience they offer. We utilized multisensory participant observations and interviews to empathize with the target users and gain insights into their needs. The results showed that they were generally positive about travel, particularly autonomy, achievement needs, and socializing with other individuals. The findings also shed light on their desire to play games on their phones. Consequently, based on the findings and the theoretical groundings of PERMA model and MDA framework from positive psychology and game design, the study proposed a gamified approach to future tourism app design for people with visual impairments, which could enhance engagement, motivation, and enjoyment in the tourism experience.

Effective training to improve serve speed is important for competitive tennis players. The purposes of this study were to investigate the effects of anthropometric factors and whole body kinematics of elite players on ball speed and to propose possible training strategies for improving the quality of tennis serves. Body and racket kinematics of tennis serves of 12 male elite Hong Kong players were investigated. The tennis serve was divided into four phases: I) Back-Swing Phase, II) Lead-Leg-Drive Phase, III) Forward-Swing Phase, and IV) Follow-Through Phase. It was shown that racket-side knee range of motion during phases II and III (r=0.705; p<0.05), racket-side knee peak extension velocity during phase II (r=0.751; p<0.01), racket-side hip peak extension velocity during phase II (r=0.657; p<0.05), racket-side shoulder range of motion in the coronal plane during phase III (r=0.616; p<0.05), racket-side elbow peak extension velocity during phase III (r=0.708; p<0.01) and body mass index (r=0.577; p<0.05) were significantly correlated with ball speed. Body mass index and the identified kinematic parameters that were significantly correlated with ball speed could be used as training guidelines for coaches and players to improve serve speed. Players should pay particular attention in training to increasing the extension velocity and range of motion of the identified joints.

Privacy is often overlooked in Hong Kong nursing homes with the majority of elderly residents living in shared bedrooms of three to five people. Only a few studies have used Bluetooth low energy indoor positioning systems to explore the relationship between privacy and social interaction among elderly residents. The study investigates the social behavioural patterns of elderly residents living in three-bed, four-bed, and five-bed rooms in a nursing home. Location data of 50 residents were used for the identification of mobility and social interaction patterns in relation to different degrees of privacy and tested for statistical significance. Privacy is found to have a weak negative correlation with mobility patterns and social behaviour, implying that the more privacy there is, the less mobility and more formal interaction is found. Residents who had more privacy did not spend more time in social space. Residents living in bedrooms that opened directly onto social space had higher social withdrawal tendencies, indicating the importance of transitional spaces between private and public areas. Friends’ rooms were used extensively by residents who had little privacy, however, the concept of friends’ rooms have rarely been discussed in nursing homes. There is evidence supporting the importance of privacy for social interaction. Future study directions include considering how other design factors, such as configuration and social space diversity, work with privacy to influence social interaction.
