Brief summary

The scientific literature shows that there is a degradation of balance in virtual reality. This trial investigates the introduction of a full-body avatar and/or enhanced visual cues on the reduction of the degradation.

Interventions

OTHERIntervention A : virtual environment with avatar

30-second right and left unipodal static and dynamic balance test with avatar only

OTHERIntervention B : virtual environment with reinforced visual signal

30-second right and left unipodal static and dynamic balance test with reinforced visual signal only

OTHERIntervention C : virtual environment with avatar and reinforced visual signal

30-second right and left unipodal static and dynamic balance test with avatar and reinforced visual signal

OTHERIntervention D : real environment

30-second right and left unipodal static and dynamic balance test in real environment

Design outcomes

Primary

Measure	Time frame	Description
Area of CoP (Center of pression) for each test (in cm²)	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
Total distance covered by the CoP during the balance test (in cm)	Immediately after inclusion	Mesure of the total distance covered by the CoP during the balance tests (in cm) in virtual condition and real condition, order in terms of randomisation

Secondary

Measure	Time frame	Description
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
