Today’s, especially the future’s, industrial focus is seriously being shifted towards new industrial revolutionized concept termed as industry 4.0. Everything associated with the industry (e.g. production machines, tools, facilities, systems, operations, components, services, products and environments etc.) is assumed to be digital and smart. So far, the industry 4.0 concept has been laid on the nine pillars or the building blocks which include; 1) the industrial internet of things (IIoT), 2) cloud computing (CC), 3) big data (BD), 4) simulation, 5) augmented reality (AR), 6) additive manufacturing (AM), 7) horizontal and vertical systems integration, 8) autonomous robots, and 9) cyber security. Augmented reality (AR) is considered as the important pillar which has been filtered out to comprehensively review in this paper. In order to capture uniform data picture, numerous search engines are used to collect the published data within the period of recent five years (2015-2019). The concept of AR connects the real world to the easily modifiable virtual world. Various sectors of AR has been found in literature which are widely scattered in various domains. It has been found that the use of AR is either objective-specific or area-specific. The implementation of AR based on the industry 4.0 concept has been practiced in industry but not on a large scale. Regarding the future work, there is a need of developing some standard procedures and guidelines which can be considered as common leading points for each and every domain of AR.Today’s, especially the future’s, industrial focus is seriously being shifted towards new industrial revolutionized concept termed as industry 4.0.
