Design and evaluation of an immersive virtual reality environment based on visuo-motor conflict.

Development of an adaptive audio system generated in real-time according to the user's movement frequency.

Scientific contribution: experimental protocol, data analysis, EEG, UX, and presence measurements, writing research reports.

Creation and development of a virtual reality environment representing a chaotic city to model, induce, and measure stress in users in an immersive situation.

The project's objective was to understand how different sensory elements—particularly urban audio—influence stress, cognitive load, emotional perception, and the sense of presence in an immersive environment.

In this context, I designed an adaptive audio system that can modify sound characteristics (density, intensity, directionality) in real-time based on user behavior or state. This system was integrated into the VR environment to precisely study the impact of auditory stimuli on physiological and subjective responses.

🔍 Key Responsibilities:

Design of the complete experimental protocol (VR, audio, physiological measures, questionnaires)

Setup of a realistic and optimized VR environment to induce controlled stress

Integration of immersive audio signals and creation of an adaptive system based on user behavior

Data collection and analysis (stress, EEG, physiological responses, behavior, UX)

Evaluation of presence, engagement, cognitive load, and user comfort

Statistical processing, data visualization, detailed reports

Production of recommendations for improving complex VR environments, particularly for training, simulation, or psychophysiological research

🎯 Project Objective

Understand how the combination of VR + immersive audio can modulate stress and improve the design of immersive environments, with a view to applications in training, safety, psychology, and neuro-ergonomics.

Within this international collaboration, I also supervise two PhD students working on virtual reality, neuroscience, and the analysis of cybersickness and interaction models in immersive environments.

We are jointly exploring advanced approaches based on EEG, optic flow, AI, and adaptive systems to better understand cognitive and emotional responses in complex VR environments.

Recently, I also secured MyTIGER Malaysia funding, a program supporting the development of innovative technological solutions. This funding strengthens our research activities, allows for the acquisition of specialized equipment, and advances us towards concrete applications in immersive training, operational safety, and psychophysiological analysis.
