Abstract
The aim of this study is to review academic papers on the applications of smart glasses. Among 82 surveyed papers, 57 were selected through filtering. The papers were published from January 2014 to October 2020. Four research questions were set up using the systematic review method, and conclusions were drawn focusing on the research trends by year and application fields; product and operating system; sensors depending on the application purpose; and data visualization, processing, and transfer methods. It was found that the most popular commercial smart glass products are Android-based Google products. In addition, smart glasses are most often used in the healthcare field, particularly for clinical and surgical assistance or for assisting mentally or physically disabled persons. For visual data transfer, 90% of the studies conducted used a camera sensor. Smart glasses have mainly been used to visualize data based on augmented reality, in contrast with the use of mixed reality. The results of this review indicate that research related to smart glasses is steadily increasing, and technological research into the development of smart glasses is being actively conducted.

With the development of information and communication technology, various forms of wearable devices that can replace smartphones are receiving attention
Smart glasses are a type of wearable device that can be worn on the face, and they meet the original objective of enabling clearer vision in addition to functioning as a computer
Based on the Qualcomm Snapdragon XR1 platform, we focused on maximizing the battery performance and increasing the artificial intelligence processing power while maintaining ofof use based on model of smart glasses
Summary
With the development of information and communication technology, various forms of wearable devices that can replace smartphones are receiving attention. Since Google released “Google Glass” in 2012, companies such as Sony, Microsoft, and Epson have launched their own smart glass products. They support wireless communication technologies, such as Bluetooth and Wi-Fi, and can be used to search and share information in real time through an internet connection. By providing a location tracking function through the Global Positioning System (GPS), it is possible to develop various applications based on location information. By using a camera mounted in front of the device, it is possible to acquire photographs or video data of the surrounding environment in real time [2]
