Title: Just Walk Out Technology (JWO)/ AmazonGo Authors: Lumen, Christine Abstract: This paper examines Amazon Go’s Just Walk Out (JWO) technology as a leading example of Internet of Things (IoT) integration in automated retail. The study explores how multiple sensing modalities—such as depth-sensing cameras, load cells, and RFID tags—operate through sensor fusion to enable seamless, real-time inventory tracking and automated checkout. Through an analysis of the system’s, the paper explains how structured light and Time-of-Flight (ToF) sensors capture three-dimensional spatial data, while edge computing nodes process information locally to minimize latency and enhance accuracy. The findings highlight how sensors in combination with cloud computing systems supports rapid decision-making. Moreover, the study discusses the possible challenges the system may encounter and proposes solutions to address them. While Amazon Go represents a significant milestone in smart retail, its success also highlights that much work remains to be done before such fully autonomous systems can be widely implemented.
