The Gamer’s Brain, part 3: The UX of Engagement and Immersion (or Retention) – GDC17 talk

This is the last part of my GDC trilogy about the gamer’s brain (how cool is that!). A warm thanks to all of you who liked my previous talks, gave me constructive feedback, and supported me! 🙂

This post is a transcript of my talk with the slides. You can find transcripts of the first two parts of my Gamer’s Brain talks here and here. If you’re interested, you can also check my book. Thank you!

The Gamer’s Brain, Part 2: UX of Onboarding and Player Engagement (GDC16)


These are the slides from my GDC 2016 presentation. This session is meant as a follow-up to my GDC 2015 talk about How Neuroscience and UX Can Impact Design (hence, “part 2”). Since it seemed to generate interest, I wanted to do a deeper dive on one of the critical aspects of a game’s user experience: the UX of onboarding and player engagement. You can watch the video of this presentation here.

Cognitive Psychology Applied to User Experience in Video Games

This article was originally published by Springer in February 2016 as part of the Encyclopedia of Computer Graphics and Games. Article reproduced here with their authorisation. 



The user experience (UX) entails a person’s perceptions and interactions with a product or software (such as a video game) and the satisfaction and emotions elicited via this interaction. UX overall refers to an over-arching discipline focused on evaluation and improvement of users’ experience of a given product or software in development.

Cognitive psychology is a discipline dedicated to understanding the human mind via mental processes such as problem solving, language, perception, attention, and memory.

UX Invaders: We Come In Peace!

User Experience (UX) is becoming very trendy albeit fairly new in the video game industry, so there are still a lot of misconceptions regarding what it is (and what it’s not). I will try to tackle these misconceptions and convince you – if need be – that UX is indeed your friend.

To explain it in a nutshell, UX explores how it is like for the target audience (the players) to experience your game (and everything beyond, such as downloading the game, consulting forums, etc.). It uses neuroscience and psychology knowledge and applies game user research methodologies (e.g. playtests and analytics) to make sure that the game has good usability and is immersive (although I prefer to refer to it as gameflow).

When thinking about my experience advocating for UX (or neuroscience) in a game development team, there are 5 main misconceptions about UX I very frequently need to address:

GDC Europe 2014 / MIGS 2014 talk

I’m sharing here my slides from my GDC Europe 2014 presentation, which I also gave at MIGS 2014 (How we are using UX Practices on Fortnite). Since I didn’t find any good slide sharing plugin (speaking of bad UX…) I just added all the slides in jpeg and put my speaker notes below.  😉

The content of this presentation is a mix of academic theories, Ubisoft Design Academy training about usability, and my own experience interacting with game teams. The following is certainly not set in stone – it’s a constant work in progress – and I’d be very interested to get your feedback.
