  EXTENT: Executive Functions Testing in VR with Embodied Cognition

  VR and Psychotherapy Virtual Reality

  Joint program between Hanyang University, University of Nantes, Nantes University Hospital, and Hanyang University Hospital to design, built, and test embodied cognition-based franco-korean VR environments for testing executive functions. 7 Korean students spent 6 months in Nantes, and 7 VR environments were built to assess several executive disfunctions. The project continued with a postdoctoral contract to further develop and test 3 environments.

(2023) Future Immersive Healthcare Experience in Medical and Home Setting in Proceedings of the 2023 ACM International Conference on Interactive Media Experiences Workshops (IMXw '23), Nantes, France, June doi Show abstract The rising accessibility of immersive media technologies opens the opportunity to use them easily in in-hospital and home environments for healthcare. The possibility to completely immerse users or patients in virtual environments, or to augment their surroundings, while tracking their movements and physiological reactions, provide new ways to induce or analyze user experiences. In the healthcare context, immersive media give new opportunities for diagnosis through the study of patient behaviors in controlled environments, as well as rehabilitation, by enabling patients to train in specific and personalized controlled tasks. In an at-home context, immersive media give opportunities to monitor and train mental and physical skills in order to improve users’ health and/or well-being. Care IMX is a half-day workshop of the IMX 2023 Conference, bringing together interdisciplinary medical, technological and social science researchers.

(2024) Three Virtual Reality Environments for the Assessment of Executive Functioning Using Performance Scores and Kinematics: an Embodied and Ecological Approach to Cognition in Cyberpsychology, Behavior, and Social Networking, 27(2), 127-134. doi Show abstract Virtual reality is an attractive technology for cognitive assessment because it provides a more embodied experience than typical test situations using, for example, paper and pencil. In addition, virtual reality can immerse individuals in complex situations similar to real-life situations, thereby improving the ecological validity (i.e., face validity) of the assessment. Virtual reality can also provide improved scoring of tests as it facilitates the tracking of kinematic information and the temporal tracking of activities. This study assesses the correlation between scores on executive function assessments using standard neuropsychological tasks in paper-and-pencil format, on a tablet, and in three immersive virtual reality environments, each designed to involve specific aspects of executive function. This study also aims to assess the correlation between these performance scores and a set of kinematic measures (speed, duration, distance of the hand) collected in virtual reality. The outcomes (performance score and kinematic measure) correlate with previous assessment methods (paper and pencil and computerised 2D) and with each other, suggesting their potential usefulness in clinical and research contexts. The discussion focuses on the advantages of embodied, situated and spatialised tests for cognitive assessment and the benefits of kinematic tracking in virtual reality tests for the quality of this assessment.

  HOMERIC: Hybridization of methOds for Modeling ExpeRIenCe in interactive systems

  Affordances Experience analysis and modelling VR and Psychotherapy Virtual Reality

  Our goal is to propose concepts, methods, and models for the study of user experience in virtual reality. We explore an hybrid approach that associates qualitative and quantitative methods, particularly first and third person methods. Our applicative aim is to build an affordance-based VR environment for elicitating several Rdoc dimensions associated to depression.

Il s’agit de souligner l’importance de l’expérience vécue explicitée pour affiner la compréhension des processus psychologiques, en prenant ici comme exemple la notion de flexibilité psychologique. Nous décrivons d’abord le “retour” du phénoménologique dans les modèles en psychologie actuelle dans un bref aperçu théorique, puis nous présentons des résultats du projet HOMERIC qui enrichissent notre compréhension du processus complexe qu’est la flexibilité en nous appuyant sur l’entretien d’explicitation comme outil mobilisé dans l’étude d’une situation expérimentale.

  Revistim-X: Virtual Reality and Brain Stimulation: an experiential approach

  Experience analysis and modelling VR and Psychotherapy Virtual Reality

  This was the first feasability and acceptability study of the association of cerebral stimulation and virtual reality for treatment in psychotherapy. We designed and built an environment related to acrophobia, and analyzed patients' experiences using mixed methods. The project continues with the development of the EVEREST VR environment.

The Revistim platform consists in several hardware devices and software tools for the immersion of subjects, the collection of various subjective, physiological and behavioral data as well as the use of new psychotherapeutic systems. The platform is used both for research in neuro-psychiatry (diagnosis, rehabilitation and treatment) and user experience modeling. Considering care, the main objective is to propose personalized care in psychiatry through the assessment of the patient state, the priorisation of targeted interventions, and an efficient evaluation of the VR therapy on the different dimensions of the disease.

(2022) Feasibility of combining transcranial direct current stimulation and full embodied virtual reality for visual height intolerance: a double-blind randomized controlled study in Journal of Clinical Medecine 2022, 11(2), 345; doi Show abstract Background: Transcranial direct current stimulation (tDCS) and virtual reality exposure therapy (VRET) may be used to reduce anxiety in visual height intolerance (vHI). Objective/Hypothesis: Our study aims to in-vestigate the feasibility of the association between wireless tDCS and full embodied 360° VRET to reduce anxiety in vHI. Methods: We carried out a randomized, double-blind, controlled study to associate VRET with tDCS by targeting the ventromedial prefrontal cortex in 28 participants. Primary outcomes were the sense of presence level and the tolerability. Secondary outcomes were the anxiety severity and the salivary cortisol concentration. Results: We confirmed the feasibility of the association tDCS+VRET with a good sense of presence without severe adverse effect. tDCS was not superior to sham to reduce anxiety. We observed in two groups a significant reduction of anxiety after stimulations but a significant increase in anxiety at each level of difficulty. Cortisol concentration significantly decreased in the sham group but remained stable in the tDCS group. Conclusion: Our study confirms the feasibility of the association between wireless tDCS and full embodied VRET with a validated environment to induce anxiety. Effects of VRET seem to be stronger than tDCS effects.
