This study aims to assess the impact of the choice of visual feedback solution (immersive via CAVE and VR headset; non-immersive via screen only) on driving performance and quality of experience on a physical driving simulator and its acceptability to wheelchair drivers with neurological disorders.
The device under investigation is an electric wheelchair driving simulation solution driving simulation solution for electric wheelchairs, based on a physical physical simulation device that integrates software allowing virtual virtual immersion. This device will be coupled with three visual simulation solutions: a virtual reality helmet, a CAVE (virtual reality room where video virtual reality room where video projectors display content on four sides) and a non-immersive projection (screen only, non-immersive virtual reality solution). This device is intended to allow patients who may acquire a power wheelchair to train in a virtual environment, which is conducive to the safety of the training, its repetition, and to produce more varied training environments, richer and more adapted to specific and individualised needs. These solutions could facilitate access to real driving for patients who are currently experiencing learning difficulties.

number of the collisions with the environment on the standardised circuit
It will be compared in 4 conditions : * immersive 1: physical simulator and CAVE\_condition A1 * immersive 2: physical simulator and virtual reality helmet\_condition A2 * non-immersive 1: screen and physical simulator\_condition B1 * non-immersive 2: screen only without simulator\_condition B2 Day 1 : A + B Day 8 : A + B
Time frame: During the driving course, from the beginning to the end of the circuit.
the time taken to complete the course
It will be measured, in minutes and seconds, under the various conditions
Time frame: During the driving course, from the beginning to the end of the circuit.
evaluation of driving performance with Wheelchair Skill Test (WST-Q-T 5.1)
The Wheelchair Skill Test (WST-Q-T 5.1) will be completed by two evaluators after each condition. The score will be between 0 to 22, a high score will represent a good driving performance
Time frame: Immediately after intervention
visual information (VICON® system)
The number of head movement will be measured by VICON system.
Time frame: During the driving course, from the beginning to the end of the circuit.
the cognitive load of carrying out the circuit with National Aeronautics and Space Administration Task Load Index
The cognitive load of tests under each conditions will be measured by the NASA-Task Load Index. It is in the form of six scales where the participant must assign a score between zero and one hundred to each of them, score indicating a growing level of intensity. Three dimensions relate to the demands imposed on the subject (mental, physical and temporal demands) and three to the interaction of a subject with the task (effort, frustration and performance)

Driving course with obstacles on a screen only
Time frame: Immediately after intervention
sensation of immersion and the feeling of presence in a virtual situation (Igroup Presence Questionnaire IPQ)
It will be evaluated and compared by Igroup Presence Questionnaire IPQ.
Time frame: Immediately after intervention
discomfort of driving in immersive reality,
The occurrence of kinetosis will be evaluated with Graybiel score by the two evaluators after each passage in each condition. The score is between 1 to 50. A high score shows the patient's discomfort.
Time frame: Immediately after intervention
satisfaction of the testers and the acceptability of the various conditions simulated
Patients will be asked to rate their satisfaction on a scale of 0 to 10, with 10 being very satisfied.
Time frame: Immediately after intervention
the acceptability of the various conditions simulated
Evaluation of acceptability with Unified Theory of Acceptance and Use of Technology (UTAUT) after each condition
Time frame: Immediately after intervention
