Conditions
Brief summary
Validate a virtual environment by demonstrating a non modification of the characteristics of postural reaction and displacement of the body's center of pressure between a real environment and the same environment in immersive virtual reality.
Interventions
OTHERstatic balance
30-second right and left unipodal static balance test
OTHERdynamic balance
for the unipodal dynamic balance test, 4 movements will be done by the volunteers in this order : * 180° elevation of the arms * lowering of the arms on the side of the single-legged support to the horizontal position * 180° horizontal translation of the arms * return from the horizontal to the starting point

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Area of CoP (Center of pression) | Immediately after inclusion | Mesure of area of center of pression during the balance tests in virtual condition and real condition, order in terms of randomisation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Total distance covered by the CoP during the balance test (in mm) | Immediately after inclusion | Mesure of the total distance covered by the CoP during the balance tests (in mm) in virtual condition and real condition, order in terms of randomisation |
| Simulator Sickness Quantifying (SSQ) | Immediately after the balance test | SSQ completed after the balance test, SSQ is a scale of cyber sickness, from 0 to 48. |
