[Ieee_vis] Call for Participants

[Romain Bourqui]

Hello everyone, 

We apologize for the potential multiple receptions.

We are reaching out today because we are looking for participants for a scientific study. We need at least 90 participants for this study. That’s a lot, so everyone’s participation is a huge help.

What is the context of this study?
Today, the media allows us to stay informed and connected. However, the amount of new information each day is enormous, and it is impossible to read it all. Not to mention that everyone’s interests are different. 
Fortunately, recommendation systems allow us to select a subset of news articles based on your preferences. 
The goal of our study is to better understand how these recommendations and the information they contain affect users, not to perfect these recommendation systems.

So, what exactly am I expected to do? 
We are looking for participants for a two-stage study. In the first stage, you will be asked to fill out a demographic questionnaire and rate a set of news articles based on their title and a short description. This stage is essential so that we can provide personalized recommendations tailored to your profile in the second stage.

The second stage will take place around three weeks later. This timeframe is necessary to allow us to recruit enough participants for the first stage and train our models. During this second stage, you will be asked to rate a set of recommendations and complete a final questionnaire. 

Great, and how long does it take?
The duration can obviously vary from person to person, but the estimated time is about 30 minutes for each stage.

Who can participate?
To participate, you must: 
Be of legal age
Have normal or corrected vision
Understand English (minimum B2 level) as the entire experience is in English
You did not participate in the first experiment in November 2025
Use a computer or a tablet (the experience is not guaranteed to work on a phone)

Why is it important to participate?
In science, it’s important to include as many participants as possible in our studies to ensure the reliability of our results. A phenomenon observed for 3 individuals cannot be generalized; but when observed for 100, it’s already much more reliable. Every contribution is a big help. If you can’t participate, you can share this message to help us.

I’m convinced. How do I participate?
To participate, simply visit the following website: 
http://ece-research.fr/ 
(Please note: this is http, not https)
Once on the page, click “Participate” and follow the instructions. 

If you have any questions, we are of course available at the following address:

Thank you all for your help! Do not hesitate to share this user study with your friends, colleagues, and family.
