The amount of arable land is limited, yet the demand for agricultural food products is increasing. This issue has led to the notion of precision farming, where smart city-based technologies (e.g., Internet of Things, digital twins, artificial intelligence) are employed in combination to cater for increased production with fewer resources. Widely used in manufacturing, augmented reality has demonstrated impactful solutions for information communication, remote monitoring and increased interaction. Yet, the technology has only recently begun to find a footing alongside precision farming solutions, despite the many benefits possible to farmers through augmenting the physical world with digital objects. Therefore, this article reflects on literature discussing current applied solutions within agriculture, where augmented realty has demonstrated a significant impact for monitoring and production. The findings discuss that augmented reality must be coupled with other technologies (e.g., simultaneous localization and mapping algorithms, global positioning systems, and sensors), specifically 9 are identified across 2 application domains (livestock and crop farming) to be beneficial. Attention is also provided on how augmented reality should be employed within agriculture, where related-work examples are drawn from in order to discuss suitable hardware approaches and constraints (e.g., mobility).

Digital twin (DT) is one of the key concepts of the fourth industrial revolution (Industry 4.0). A DT is a data-driven, digital replica of a real-world object or environment, including all the states and behaviour of the real-life counterpart. Based on research across multiple domains, DTs show great potential to improve both efficiency and sustainability. In addition, a DT is able to remove key constraints of human observations and interactions. Yet, the technology is still in its infancy. Thus, this article presents a literature search across five different databases focusing on suitable approaches for data coupling and the stages of DT implementation integration with Industry 4.0 technologies. The review process follows the systematic literature review (SLR) methodology. The selected articles cover a wide range of DT implementations across the agricultural industry, ranging from arable farming to aquaponics. Findings include identification of the stages needed to create the DTs, the data coupling processes, and how Industry 4.0 technologies (e.g., cloud-based technologies, IoT, and AI subfields) are integrated. Findings presented in this article will support others in the design of DTs and integration of Industry 4.0 technologies for agricultural greenhouses.

As a concept that is somewhat under emergence, the notion of the Metaverse varies across different academic articles. Yet there is a shared view on the benefits to its ongoing implementation, particularly for digital art, where the technology can provide a new metric for artists to showcase and sell their artwork to a global audience with minimal barriers, and for consumers to have an unbounded experience not limited by physical space or museum entry fees. In this article, a contribution is provided to a broader conversation about the future of the digital art and the Metaverse and its role in shaping our online culture. We discuss the concept of the Metaverse, its structure, the role of artificial intelligence and the benefits (and limitations) the technology holds for digital art. For a case study, we develop a 3D art gallery housing an art collection generated using artificial-intelligence-based techniques such as diffusion models. A total of 67 individuals are surveyed from three pools (two in-person and one online-based), with questions relating to the future of digital art, the Metaverse and artificial intelligence. Findings include that the majority of participants were familiar with the concept of the Metaverse and overall, they had a predominately optimistic view of both the use artificial intelligence for art, and the use of the Metaverse to support digital art, with 85.3% of the participants having already seen artificial-intelligence-based artwork. The identification of consumer segments further highlights the importance of finding customised solutions, considering consumers’ heterogenous preferences for AI-generated art. Research presented in this article will be beneficial for those looking to explore the Metaverse for artwork and develop virtual galleries, and the findings further highlight the Metaverse as a potential democratising force in the art world.
