Production Jan/Feb, 2024 What is Augmented Reality in Manufacturing? By Wendy Mlynarek, Strategic Business Development Director for DELMIA, Dassault Systèmes
what it means from an entertain- ment perspective, what is its role in a manufacturing work envi- ronment? Often assimilated as a strange term in science fiction movies, augmented reality is now closer to everyday life and gradually evolving into the in- dustrial world. Augmented reality (AR)
Y
technology integrates virtual ele- ments in 3D (in real-time) within a real environment. The princi- ple is to combine the virtual and the real worlds digitally to pro- vide perfect integration. Before continuing, it is im-
portant to understand the differ- ence between all the different ex- isting technologies: mixed reali- ty, virtual or augmented reality. Augmented reality doesn’t just superimpose virtual information onto an image, but also inte- grates synthetic information in the real environment. Conversely, virtual reality
(VR) immerses a user in reality entirely generated and assisted by a computer. Immersion is typ- ically enabled by hardware de- vices such as VR goggles, virtual reality headsets, or walled rooms with video screens to fill the user’s entire field of view. VR brings an immersion in a 100%

synthetic/digital environment. A new term, augmented vir-
tual reality, is another way of characterizing virtual data. Here, digital data is not dis- played in a real environment, but the opposite. One or more pieces of information from the real world is imported and dis- played in a digital environment. Mixed reality is a fusion be-
tween real and virtual worlds where digital and physical ob- jects (e.g. mixed reality headsets) cohabit to create new environ- ments.
Mixed reality is differentiat-
ed by a very specific interaction of digital content with physical space. Nevertheless, it remains a dimension that covers all forms of augmented reality, that is, all degrees of fusion between the real and virtual worlds. To summarize, augmented
reality brings digital content di- rectly into the real world, virtual reality displays physical infor- mation in a digital environment, and mixed reality is similar to augmented reality.
Augmented Reality Augmented reality adds vir-
tual information (texts, anima- tions, images, 3D models, etc.) into the real environment. To do this, augmented reality inlays this information into the user’s
environment in different ways. Elements can be displayed in a video stream viewed on a screen or tablet. The latter then be- comes a window into the world with virtual information embed- ded. Information could also be displayed on lenses in the user’s vision — smart glasses or a head- set. A projector could be used to display information directly on a physical object. However, this information
must be embedded in the right place and it’s necessary to know the location where it resides. For this purpose, we use one or more sensors to ensure the data loca- tion.
Augmented reality solutions
are therefore distinguished by means of restitution, the means of capture, and the way they use the latter to localize themselves. The solution’s first category
aims to locate itself in relation to the global environment. For ex- ample, using cell phone sensors (GPS, inertial navigation system, cameras, etc.) allows one to locate oneself outdoors (PokemonGo, GoogleMaps or LiveView). It dis- plays information that remains stable in relation to the world. In the same way, other solutions allow us to locate ourselves in- doors and to place elements that will remain anchored and stable in our environment.
Advantages In the future, augmented re-
ality can reshape many aspects, such as the increased compe- tence of operators and their way of interacting with a real work- ing environment by importing digital data. This replaces the time-con-
suming, manual processes of the past and makes task execution much faster and simpler. In ad- dition, AR brings multiple gains in the industrial environment, whether remote visualization, better information transmission, or field data feedback to the dig- ital twin. The data collected with aug- mented reality can be used to

promote the digital transforma- tion of information, optimize in- dustrial processes and contribute to better traceability. To choose the right use case,
efforts and research should be fo- cused on operations that gener- ate costly defects (non-confor- mances), long or unscheduled downtime, plant safety problems or high customer dissatisfaction. Today, everything deploys
and evolves very quickly, and the same goes for these AR technolo- gies that will continually evolve
and improve. Contact: DS Americas Corp.,
