System and method for testing the vision of a subject

A method for testing the vision of a subject, said method comprising the steps of:

• providing a head motion sensing device, the head motion sensing device configured to measure a velocity or speed of the head of the subject;
• providing an eye movement tracking device, the eye movement tracking device configured to measure an eye movement of the subject;
• providing a visual display device having an output screen, the visual display device configured to display one or more visual objects on the output screen so that the one or more visual objects are visible to the subject;
• providing a data processing device, the data processing device operatively coupled to the the head motion sensing device, the eye movement tracking device, and the visual display device;
• positioning the subject in front of the output screen of the visual display device such that one or more visual objects are visible to the subject;
• displaying one or more configurations of the one or more visual objects on the output screen of the visual display device when the subject's head undergoes displacement at a velocity or speed within a predetermined range as measured by the head motion sensing device;
• and
• determining, by using the data processing device, an eye performance parameter related to a vestibular compensation of the subject as a gaze of the subject is directed towards the one or more configurations of the one or more visual objects on the output screen of the visual display device, the eye performance parameter of the subject being determined based upon the eye movement measured by the eye movement tracking device and the head velocity or speed measured by the head motion sensing device.
