L’Oréal started its journey in Augmented and Virtual Realities in 2016 with the acquisition of its 1st Microsoft HoloLens glasses. L’Oréal is using HoloLens for different use cases
6/07/22 Visit at L’Oréal Operations site in Aulnay-sous-Bois On July 6th, 2022, Deborah, Eva, Louise and Tesi were invited to the L’Oréal Operations site in Aulnaysous-Bois, north of Paris. The objective was to exchange on the usage of the HoloLens technology and visit their MYT Center (Make Your Technology). The MYT Center is L’Oréal new structure to accelerate digital initiatives and transformation around Industry 4.0 and agile methodology.
Review new machine & installation by the operator on full scale The objective is to cobuild the equipment with the operators. To achieve it, L’Oréal is using the 3D layout of its equipment and projecting the mock-up on the shopfloor in real size. Then they review virtually the installation with the operators and discuss ergonomics, safety, performance, conflict zones…. They contribute to build the equipment and the Operations Team can feel a strong engagement. Less than 5% of employees didn’t want to participate. The prerequisite is to have the 3D Layout of each equipment. For filling & Packing, it is difficult to share the 3D file, so they are working only with the design layer. For Processing, they are using the 3D file. The equipment’s suppliers work more on Virtual Reality than on Augmented Reality, so this approach was new to them, but after using AR, they prefer it also over VR.. The layout of the shopfloor needs to be adjusted to the site specifics. For example, in Karlsruhe (Germany) the shopfloor is organized in lines when in Aulnay (France) it has a flower shape. That’s why L’Oréal
is building the layout onsite including safety, quality and the building plan. One year after the beginning of the co-building program, L’Oréal Operations had no ramp-up issue. People already accepted it and are supportive of the “pull approach” vs the initial push one. At the Sicos (société industrielle de cosmétique) Plant in Caudry (France), they detected 25 pain points under Virtual Reality and 39 additional pain points under this Augmented Reality approach. For audit purpose L’Oréal Operations will keep all 3D equipment files. They don’t have a team to create them, neither digital twin of their factories. And their CAD files are not yet well managed. They rely on the equipment provider to get the 3D models. In case needed for example for a further installation, they would include in their investment request the creation of a new 3D file from scratch instead of going back to the old documentation.

L’Oréal is encouraging its operators to use video to faster solve issues. They defined 3 procedures for assistance: -Teams: teams can help each other and use a Teams communication to solve an issue. 70-80% of the cases -Teams + Remote Assist add-on on smartphone. It provides the Augmented Reality capacity but without accurate details. Nevertheless, they estimate that it can help in 10-15% of
cases. -HoloLens + Teams + Remote Assist: the expert can push a document and guide the operator through the appropriate steps. It is handfree to facilitate manipulation and holographic for better visualization. 5% of cases but those are the ones that initially would take longer to be solved. L’Oréal could record the calls to create a resolution library but aren’t doing it today.
Remote equipment review/Audit L’Oréal is performing audits remotely using the HoloLens and Remote Assist. The main benefits are reduction of cost and time for traveling which contributes positively to reduce the
environmental impact. Today they decided to not perform all audits remotely to still keep the contact with the people on site. But technically they could.

Emergency situation In L’Oréal Vichy site, they had a major storm with hails. The roof got damaged. And due to the presence of asbestos, the area was flagged as restricted area. The equipment experts could operate on-site but thanks to the HoloLens they could guide the operators allowed in the restricted area through the procedures.
The Aulnay site changed from a skincare production to parfums. The check of the new layout had to take place during strong Covid wave providing them to go onsite. The L’Oréal Operations team was able to validate it and let the operations start without physical visit on the shopfloor.
Comissioning L’Oréal’s next objective is to perform the commissioning with the HoloLens. They want to leverage the Artificial Intelligence to
display with different colors the differences between reality and planned model, making it easier to spot the variations.
Remote Training L’Oréal is performing remote training with the trainer wearing the HoloLens. The trainees are then seeing the shopfloor and the
equipments, bringing the theory to live. Additional advantage is that the training can be recorded for later replays.
R&D L’Oréal Operations Team did a POC with the R&D team leveraging Microsoft Guide, tool to improve productivity with advanced guidance, to use the Lab
Equipment. All content was done by the operators for their colleagues. Guides is the next step when Remote Assist will be fully used.

IT integration of the HoloLens was also a challenge at L’Oréal with 2 main digital pain points: •HoloLens 2 weren’t recognized in the L’Oréal Wifi and were considered as a “visitor device”. They couldn’t know who was using the HoloLens, impacting the audit capabilities. It took L’Oréal Operations 5 years to get normal connectivity.

•The HoloLens 2 uses a strong authentication process with an extra security code that can be provided by Authenticator App, per SMS, via a phone call on a fixed phone, a cell phone or on a dedicated tablet. This topic has to be thought through as the operators usually don’t have a business cell phone and may not accept to use their private cellphone for work.

Remote Assist should be positioned as an add-on to Teams. It is enriching Teams and shouldn’t been perceive as a new tool.
Simplify the access to info, quick starts material… all informations are published in one single internal website. (Similar to our Industrial4Innovation Sharepoint page).
Onboard the operators from the beginning to facilitate the ramp-up of new equipment is making a big difference because the operators are now owning the shopfloor.
Work closely with Digital to define the authentication process and facilitate access and connection to the HoloLens, including IIOT Network.
In all new equipment contract, L’Oréal integrates the request of the 3D model of the equipment including the updates of the model to avoid having the responsibility at site level.

All employees can declare pain points. Then 12 pain points are selected per year to be worked on at the MYT, where the newest technology is available: robots, 3D printers, digital technology, virtual and augmented reality glasses…). To deep-dive on those issues, the team members are relocated to the MYT in Aulnay.
