Accidents involving infants and toddlers are occurring frequently, and if elementary measures are not smooth, they can lead to even greater accidents. Rapid elementary measures require an appropriate monitoring system, and it is necessary to build a system that can accurately monitor the child's living condition and notify the emergency situation immediately. Recently, with the development of IoT technology, various types of sensors are being developed in a very small size, and development of wearable devices connected with smart phones is accelerating with the development of smart phones. By using these wearable devices, it is possible to reduce the risk of infant accidents and to respond promptly in case of an accident. In this paper, we propose a wearable system that can monitor the infant condition and present a service to prevent infant accidents.

Smart Jewelry is applied to the components of the Internet of Things. The process of obtaining the status information to the input of the sensor. And it controls the light color of the LED. Because to express the beauty of twinkling lights that can be felt in the jewelery and aesthetic functions were applied in order to feel the mystery. Smart Jewelry is capable of communication, interaction, wearable. Smart jewelery was equipped with a color, temperature, ambient light sensor. It was designed to allow interaction with a Bluetooth module. Applying an algorithm so that the light jewelry colors can vary depending on the circumstances of the smart jewelry wearer had been implemented by the mobile application. It can be realized in digital technology and the convergence of life. It presents the orientation development of the smart jewelery device on IoT environment.

A bedridden patients, elderly people, and dementia who are subject to special care at a medical institution can not handle the feces themselves and need the help of a guardian or care-giver. In particular, toxic substances are contained in the stools, which can cause eczema, dermatitis and urticaria, so it is important to replace diapers. In this paper, we propose a wearable device design for the detection of excretions in consideration of the various excretion requirements of the elderly. The device is a form in which a module are attached to an adult diaper used in a nursing hospital to detect excreta, and the presence or absence of a wearer can be confirmed by an LED. The measured data is transmitted to the smartphone app in real time via Bluetooth in the module and can be checked for popup notification. The validity of this study was verified by comparing the actual excretion with the data collected through the designed module.

Recently, as the quality of life of the morden people has increasingly grown, the demand for traveling to foreign countries has been rapidly increasing. However, there are not enough safety systems avaliable for international travelers. Therefore, it is necessary to provide helpful information on disaster, crimes and dangerous areas by country for travelers. In this paper, we propse a smart device-based smart security notification service system for emergent situations of overseas travelers. the proposed notification system provides information about disaster, crime and dangerous areas is designed to be provided to users.

With the development of virtual reality (VR) and blockchain technology, Metaverse is being used in various fields such as games, education, and social networking. At the same time, shipments of wearable devices such as smartwatches are growing every year, becoming more and more integrated into people's daily lives. This study presents a new possibility of reflecting the user's body signals measured through the combination of the two phenomena in the metaverse character. Various biometric information such as the user's heart rate and amount of exercise collected through the smartwatch are reflected on the character in the metaverse, allowing the user's physical condition to be reflected in the virtual world. Through this, Metaverse is expected to provide a new experience that can be called 'extended reality' beyond simple virtual reality, improve user's satisfaction with Metaverse, and suggest a direction for the development of smartwatches.

In this paper, a voice, object, and optical character recognition platform including voice recognition-based smart wearable devices, smart devices, and web AI servers was proposed as an appropriate technology to help the visually impaired to live independently by learning the life cycle of the visually impaired in advance. The wearable device for the visually impaired was designed and manufactured with a reverse neckband structure to increase the convenience of wearing and the efficiency of object recognition. And the high-sensitivity small microphone and speaker attached to the wearable device was configured to support the voice recognition interface function consisting of the app of the smart device linked to the wearable device. From experimental results, the voice, object, and optical character recognition service used open source and Google APIs in the web AI server, and it was confirmed that the accuracy of voice, object and optical character recognition of the service platform achieved an average of 90% or more.

Recently, with the market of smart phones slowing down, more attention is paid to wearable devices. It was suggested that 2013 was the "year of the smart watch", due to that the majority of major consumer electronics manufacturers were undertaking work on a smart watch device. However there are still many issues on the interaction and interface design of smart watches. This study reviewed related literatures and evaluated the interaction methods, interface and content design of current smart watches. Based on that, future research directions were proposed. The research results have significant meanings for the guidance of future directions of smart watch.
