The device that is the subject of this investigation is a solution for driving simulation of an electric wheelchair. It is intended to enable patients who are likely to acquire an electric wheelchair to train in a virtual environment, favorable to the safety of training, to its repetition, and to produce more varied, rich training environments and more tailored to specific and individualized needs. These solutions will make it easier to access real-world driving for patients who are currently experiencing learning difficulties. It is expected that this investigation demonstrates the reproducibility of driving performance in electric wheelchair driving simulator compared to the real world.
As part of this investigation, it is expected to develop a driving simulator that could contribute to improving the learning of electric wheelchair driving and access to electric wheelchair for people who can not currently claim for physical risks and weak psychology for the participant in the research. The present clinical investigation aims at evaluating the performances, the safety and the satisfaction of the users with regard to a simulator of driving of electric wheelchair in virtual reality. The main objective is to evaluate the feasibility of a virtual electric wheelchair driving training, comparing driving performance in virtual reality versus reality, in identical real and virtual standardized circuits, in regular users of electric wheelchairs with neurological disorders.

Number of collision
The primary judgment criterion is the number of collisions on different standardized circuits in real condition versus virtual condition
Time frame: Day 1
Number of collision
The primary judgment criterion is the number of collisions on different standardized circuits in real condition versus virtual condition
Time frame: Day 8
Number of collision
The primary judgment criterion is the number of collisions on different standardized circuits in real condition versus virtual condition
Time frame: Day 15
Driving Speed
Speed measured by the completion time of the course on the different circuits in real condition versus virtual condition
Time frame: Day 1, Day 8 and Day 15
Wheelchair Skill Test (WST)
Driving performance measured by the Wheelchair Skill Test items corresponding to the different courses in real condition versus virtual condition
Time frame: Day 1, Day 8 and Day 15
NASA-Task Load Index
The cognitive load of tests under both 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)
Time frame: Day 1, Day 8 and Day 15
Ease of Use Questionnaire
The satisfaction of the use of the electric wheelchair under the conditions will be evaluated by the self-questionnaire Ease of Use Questionnaire. It measures the subjective usability of a product or service. It is a 30-item survey that examines four dimensions of usability: usefulness, ease of use, ease of learning, and satisfaction. The questionnaires were constructed as seven-point Likert rating scales. Users were asked to rate agreement with the statements, ranging from strongly disagree (1) to strongly agree (7).
Time frame: Day 1, Day 8 and Day 15
Unified theory of acceptance of technology questionnaire (UTAUT)
Questionnaire of acceptability / acceptance of the tool and its use by patients based on the Unified Theory of Acceptance and Use Technology (UTAUT).
Time frame: Day 1, Day 8 and Day 15
Igroup Presence Questionnaire (IPQ)
The IPQ comprises 14 items rated on a seven-point Likert Scale ranging from -3 to 3. The general item assesses the general "sense of being there", and has high loadings on all three factors, with an especially strong loading on Spatial Presence. The Spatial Presence sub-scale is related to the sense of being physically inside the virtual environment. The involvement sub-scale is directed to evaluate the attention devoted to the virtual environment. The realness sub-scale evaluates the sense of reality attributed to the virtual environment.
Time frame: Day 1, Day 8 and Day 15
The learning effect
The learning effect on the virtual circuit and on the real circuit, will be evaluated by progression / stabilization of the time of realization during the sequence of repetitions.
Time frame: Day 1, Day 8 and Day 15
Graybiel score
Assessment of discomfort and motion sickness to quantify the intensity of different symptoms during motion sickness.
Time frame: Day 1, Day 8 and Day 15
