This article aims to provide a better understanding of Augmented Reality Smart Glasses (ARSG) for assembly operators from two perspectives, namely, manufacturing engineering and technological maturity. A literature survey considers both these perspectives of ARSG. The article's contribution is an investigation of the current status as well as challenges for future development of ARSG regarding usage in the manufacturing industry in relation to the two perspectives. This survey thereby facilitate a better future integration of ARSG in manufacturing. Findings include that commercially available ARSG differ considerably in their hardware specifications. The Technological Readiness Level (TRL) of some of the components of ARSG is still low, with displays having a TRL of 7 and tracking a TRL of 5. A mapping of tracking technologies and their suitability for industrial ARSG was done and identified Bluetooth, micro-electro mechanical sensors (MEMS) and infrared sensors as potentially suitable technologies to improve tracking. Future work identified is to also explore the operator perspective of ARSG in manufacturing.

本文旨在从制造工程和技术成熟度两个角度为装配操作者提供对增强现实智能眼镜（ARSG）的更好理解。文献调查考虑了ARSG的这两种观点。这篇文章的贡献是从两个角度对ARSG在制造业中的用途进行了研究，并对ARSG的未来发展提出了挑战。因此，该调查有助于将ARSG更好地集成到制造业中。研究发现，商用ARSG的硬件规格差异很大。ARSG某些组件的技术准备水平（TRL）仍然很低，显示器的TRL为7，而TRL为5。对跟踪技术及其对工业ARSG的适用性进行了映射，并确定了蓝牙，微机电传感器（MEMS）和红外传感器是改善跟踪的潜在合适技术。确定的未来工作还将探索ARSG在生产中的运营商视角。
