  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.

  VR for Executive Functions testing: Development of VR and IoT-based Systems for Evaluation of Embodied Cognition

  VR and Psychotherapy Virtual Reality

  Joint program between Hanyang University, University of Nantes, Nantes University Hospital, and Hanyang University Hospital on the use of VR environments for the testing of executive functions in VR. 7 Korean students spent 6 months in Nantes, and 7 VR environments were built to assess several executive disfunctions. The project continues with a postdoctoral contract.

  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.

(2018) New VR Experiences for the Personalization of Care in Psychiatry: the Example of ReViSTIM Project in Care TVX Workshop at ACM TVX 2018, June 2018, Seoul, South Korea. doi Show abstract This paper presents a new VR platform in hospital environment for the study of mental diseases. 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.

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

  Experience analysis and modelling VR and Psychotherapy Virtual Reality

  This second study on the association of cerebral stimulation and virtual reality for treatment in psychotherapy deals with rumination, a dimension of depression. In this study we collect data with questionnaires, EEG, eye-tracking, and micro-phenomenology.
