“Articles such as clothes, watches, shoes, and accessories are essential to people around the world. However, going beyond the basic roles and purposes of these items, the concept of “wearability” is rapidly evolving to include computing power and the ability to connect to the internet. In other words, information, communication, and technology (ICT) are beginning to be integrated into wearables. Because wearable electronics can provide a more comfortable and convenient life for wearers, research on and the development of wearables have emerged as major interests both academically and industrially. In particular, a wearable information display for intuitive communication between wearers and wearable devices has attracted a great deal of attention, and it can create additional value in the fashion, military, automobile, and architecture industries while also making functional wearable devices available to all.”
