AIED 2024: "Nudging Adolescents Towards Recommended Maths Exercises With Gameful Rewards"
Tags
Gamification
Image
This paper for the AIED 2024 conference is an outcome of the master's thesis by Joran De Braekeleer, which I guided and Katrien Verbert supervised. We studied how gamification can be used to nudge adolescents towards recommended exercises on a mobile app for practising math equations.

My paper with Leen Dereu for the IUI 2023 conference. It is based on Leen's master's thesis on a steering mechanism for recommended exercises. We studied how a control mechanism and a visualisation that depicts the control's impact affected adolescents' trust in a platform that recommends mathematics exercises.

Agriculture 2022: "Visually Explaining Uncertain Price Predictions in Agrifood: A User-Centred Case-Study"
Tags
Explainable AI
Visual Analytics

My journal paper for Agriculture presents a prototypical visual decision support system that incorporates price prediction, uncertainty, and visual analytics techniques. Interviews and questionnaires suggest that user-centred approaches are key for increasing the uptake of visual decision support systems in agrifood.
