Abstract: A system and method for measuring eye movement and/or eye position and postural sway of a subject is disclosed herein. The system generally includes an eye movement tracking device, a postural sway detection device, and a data processing device operatively coupled to the eye movement tracking device and the postural sway detection device. During the execution of the method, the eye movement and/or eye position of the subject is measured using the eye movement tracking device, and the postural sway of the subject is measured using the postural sway detection device. A method for determining a gaze direction of a subject during a balance test and/or concussion screening test, and a method for assessment of a medical condition of a subject are also disclosed herein.

Abstract: A system for testing the vision of a subject incorporating eye movement tracking is disclosed herein. The system includes a head motion sensing device configured to measure a velocity or speed of a head of a subject, an eye movement tracking device configured to measure an eye movement of the subject, a visual display device configured to display one or more visual objects so that the one or more visual objects are visible to the subject; and a data processing device operatively coupled to the head motion sensing device, the eye movement tracking device, and the visual display device, the data processing device being specially programmed to carry out the steps of the vision tests. A method for the testing the vision of a subject incorporating eye movement tracking is also disclosed herein.

Abstract: A system for testing the vision of a subject and/or training head-eye coordination associated with the vision of a subject is disclosed herein. The system includes 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; and a data processing device, the data processing device operatively coupled to the visual display device, the data processing device being specially programmed to carry out the steps of the vision tests and training procedures. In one or more embodiments, the system may further include a motion sensing device, the motion sensing device configured to measure a velocity or speed of a head of a subject, and the motion sensing device being operatively coupled to the data processing device.
