摘要A method for measuring the perception of spatial orientation of a person comprising the steps of: - modifying a first non visual frame of reference and providing a second non visual frame of reference and measuring the value of the parameter representative of the perception of spatial orientation; - modifying a first visual frame of reference so as to provide a second visual frame of reference and measuring the value of the parameter representative of the perception of spatial orientation; - combining the measured values of the parameters representative of the perception of spatial orientation of preceding steps so as to obtain a value representing the sensitivity of the person referred to a scale of sensitivity to perception of spatial orientation.
