En octobre 2019, Laurence Vagner (avec un V) et moi donnions un atelier à Paris Web sur la thématique des biais cognitifs. Nous avions déjà fait cet atelier en anglais pour nos workshops UX in Lux à Luxembourg. Pour la version française de l’atelier, nous avons sorti le grand jeu (huhu) et créé un jeu de 52 cartes pour vous aider à découvrir et vous sensibiliser à différents biais cognitifs.

Les biais cognitifs sont des mécanismes de pensée qui poussent le cerveau humain à tirer des conclusions incorrectes. Pour le meilleur ou pour le pire, nous pouvons les utiliser de…


J’avais discuté sur Twitter il y quelque temps des lacunes dans l’enseignement des étudiantes et étudiants en design et notamment du manque de bases de l’accessibilité et des couleurs. Cette discussion a donné lieu à pas mal de réponses intéressantes sur les outils pour mesurer l’accessibilité des couleurs, le design inclusif et quelques discussions sur les émojis.

Plusieurs personnes sont venues me demander depuis des conseils et des outils pour les aider. Plutôt qu’un long tweet, j’ai décidé de rédiger un article “aide mémoire” pour partager toutes les ressources, conseils et outils que j’utilise régulièrement pour construire et vérifier l’accessibilité…


Last year, Laurence Vagner (with a V) and I gave a workshop in Paris Web. The theme was “cognitive biases”. We had already gave this workshop in English for our UX in Lux community in Luxembourg. For the French version of the workshop, we created a 52 UX cards deck to help people discover and understand different cognitive biases. This card deck is now available in English as well.

** Si vous souhaitez une version française des cartes elle est disponible ici **

Cognitive biases are psychological thought mechanisms and tendencies that cause the human brain to draw incorrect conclusions

TLdNR: push notifications became yet another way to artificially re-engage users and force content down their throat. That’s why so many of them hate it. But there’s some interesting use cases for it. Here is some advice on how to stop ruining it for the rest of us. Spoiler alert: stop asking for permission on page load (and make them useful for users)

A few weeks ago I stumbled upon a kind of fun / trollesque site: “ Should I Add Push Notifications To My Website? — No “. That’s all fun and I understand the purpose of this site…


All the resources, tips and tools I regularly use to build and check the color accessibility of my products in one place. Enjoy.

I wrote a quick tweet about teaching the basics of accessibility and colors to design students a few months ago that go quite some attention. It brought up some interesting discussions on color accessibility, inclusive design an interesting discussion about the use of emojis.

A few people asked me for advice on how to chose accessible color palettes for their projects. So I thought I would share the resources, tips and tools I regularly use to build and check the color accessibility of my products in one single place for future reference. I will keep on updating this article with…


You might have noticed that there was a little bit of blog redesign going on here. This is because I redesigned my portfolio last week and I’m trying to make the blog match the new portfolio redesign. For the moment it’s a MVP, full static HTML and a little bit of PHP includes. There’s some design and linguistic decisions involved. In this article, I will explain a little bit the redesign process and what’s coming next.

Involving users, audience, stakeholders, partners, internal teams and developers from the start will help us build better products and services.

In many organisations, UX Design is unfortunately still often seeing as a One Person’s job, but it should not be that way. Part of my job as a user experience designer is to bring people together to help them find creative solutions to the problems they are facing. There’s a lot of methods available to UX designers to help us accomplish this. This unfortunately means that it’s also pretty easy to get lost and feel overwhelmed with the quantity of information available.

Today, I am going to share with you my list of seven ressources I use in my daily…


Color contrast is something really important in Design. It will help users read your text and get a clear understanding of your content. Color contrast and color accessibility scares a lot of designers too. Some are afraid that color accessibility will limit the color palette they will be allowed to use and so their creativity. Some people think that color accessibility is “only for people with some sort of color blindness disease” so it does not concern their target audience. Let’s be clear from the start: color contrast will concern every one of you users.
