"Marc-Olivier has been a central piece in every Nuvoola Ai project. He has a very professional and pragmatic approach on top of being an outstanding team player. He tackles any challenge with optimism and always tries to come up with original solutions. His skillset goes way beyond UX design and has helped Nuvoola Ai in many regards. I would recommend Marc-Olivier to anyone without any hesitation."

Project
The goal was to design an intelligent end-to-end solution to manage inventory and ordering processes for Rio Tinto through JRV (hardware provider). I designed both the desktop Web application and the mobile application.
Challenges
Really understand the reality of the people working in the factory and conduct a thorough user research.
Create a mobile application that can be easily used by site workers with little computer knowledge.
Have a consistent design between the desktop application and the mobile application.
Results
The project was a great experience and success. Employees are very satisfied with the experience.
What I've learned from this project is that the closer you can get to the end user, the better it is!

Storyboard
This storyboard proved very useful in making sure all project stakeholders had the same story in their head.
Personas
For this project, we didn't need complex personas. I personally don't believe in complex personas but rather personas that show metrics that have a real impact on the project value.
Design system
Desktop Application
Here are a few examples of the the desktop application, which is used by the administrators and managers of the hardware department to follow up on orders and know exactly where each hardware type is.
Mobile Application
Here are a few examples of the mobile application, which operates on a Zebra device and used by Rio Tinto employees to do the inventory.
Testing and user observation
Myself giving instructions to the client about how to use the application. I also did real-time observation of employees using the application in order to detect any UX problems.
Project
Design an interactive kiosk in retirement homes to detect people at risk of COVID using face detection and remote temperature reading.
Challenges
Kiosk interaction time had to be under 60 seconds per visitor.
I had to account for visually-impaired people when using colors on screen.
Use very simple language, both in English and French, along with animations, to speed up time spent in front of the screen.
The interaction had to be extremely simple to accommodate almost anybody.
Results
The kiosk required a lot of trial and error due to the assembly of technical components. The kiosk worked very well, and feedback was positive about the user experience.
I really liked designing something on a real physical device, like viewing distance, typography size, user screen interaction with the screen, etc.

Logical user path
Few kiosk screens
After a few tests, while taking the viewing distance from the kiosk into account, I settled for a large font size and simple icons. Screens do not contain lots of text to reduce the experience time to a minimum and simplify the experience.
Animation
If an image is worth a 1,000 words, an animation might be worth 10,000. This was the fastest way to tell visitors what to do before using the kiosk. We couldn't afford, in terms of time, to express that in words, let alone in two languages.
Testing and user observation
My team and I have tested the user experience in-house before shipping the kiosk to the clients. Once the kiosks were in place, we did real-time observation and collected data on to improve the user experience.
Project
Develop an intelligent solution to control the entry/exit of trucks on distribution sites.
Challenges
With two very different personas, develop two very different types of solution and maintain synchronization and uniformity between the two:
1) a Web application for agents to manage everything that is happening;
2) an interactive outdoor kiosk used by truckers.

2) an interactive outdoor kiosk used by truckers.
Results
This solution still enables today several distribution sites to securely automate 90% of the entry/exit of trucks and equipment, and to track who enters the site with what equipment.
The kiosk also automatically gives instructions to the trucker on where to go next on the site.

If an image is worth a 1,000 words, an animation might worth 10,000. This was the fastest way to tell truckers what to do upon their arrival in front of the kiosk. We couldn't afford to express all those instructions in words.
