In the last 30 years, several academic and commercial projects have explored the context-awareness concept in multiple domains. The concepts of ubiquitous computing and ambient intelligence are features associated with the fourth generation industry empowering space with the ability to interact and re-spond appropriately according to context. In the scope of Industry 4.0, context-aware systems aim to improve productivity in smart factories and offer assistance to workers through services, applications, and devices, delivering functionalities and contextualized content. This article, through descriptive research, discusses the concepts related to context, presents and analyses projects related to ubiqui-tous computing and associated with Industry 4.0, and discusses the main chal-lenges in systems and applications development to support intelligent environ-ments for increased productivity, supporting informed decision-making in the factories of the future. The study results indicate that many research questions regarding the analysed projects remain the same, leading the research in the con-text-ware systems area to minimize issues related to context-aware features, im-proving the incorporation of Industry 4.0 paradigm concepts.
