Abstract

The eye movement, body movement, and/or physiological performance of a subject may tracked while the subject performs a task, such as participating in an activity or sport. The collected data may then be used to identify correlations between the subject'"'"'s eyesight and the subject'"'"'s body movement exists and/or physiology. Such a correlation may be analyzed (e.g., over time) to determine any delays or gaps in the subject'"'"'s ability to track an object, such as a ball, while participating in a sport or other activity. Further, a subject'"'"'s performance may be compared to data collected from other individuals. The eye movement, body movement, and/or physiological performance data may be used to test and/or train the visual and cognitive abilities of an individual.

Claims

1. A method for testing or training the eye and body movement of a subject while the subject performs a task, the method comprising:

tracking the subject'"'"'s eye movement while the subject performs the task to produce eye movement data associated therewith;

tracking the subject'"'"'s body movement while the subject performs the task to produce body movement data associated therewith; and

determining a correlation between the subject'"'"'s eye movement data and the subject'"'"'s body movement data.

2. The method of claim 1, wherein the subject'"'"'s eye movement is tracked by an eye tracking system.

3. The method of claim 1, wherein the subject'"'"'s body movement is tracked by a body tracking system.

4. The method of claim 1, wherein tracking the subject'"'"'s eye movement includes tracking the lens of at least one of the subject'"'"'s eyes.

5. The method of claim 3, further comprising:

collecting physiological data while the subject performs the task to produce physiological data associated therewith; and

determining a correlation between the subject'"'"'s physiological data and the subject'"'"'s eye movement data and the subject'"'"'s body movement data.

6. The method of claim 3, wherein the body tracking system is at least one of an optical system and a non-optical system.

7. The method of claim 1, wherein determining a correlation between the subject'"'"'s eye movement and the subject'"'"'s body movement includes plotting the eye movement and body movement versus time.

8. The method of claim 1, further comprising:

storing the eye movement data and the body movement data on a storage device.

9. The method of claim 1, further comprising:

sending the eye movement data and the body movement data to an output device.

10. A system for testing or training the eye and body movement of a subject, the system comprising:

an eye tracking system that tracks the eye movement of a subject, wherein the eye tracking system collects eye movement data associated with the subject'"'"'s eye movement;

a body tracking system that tracks the body movement of a subject, wherein the body tracking system collects body movement data associated with the subject'"'"'s body movement; and

a computing device that correlates the subject'"'"'s eye movement with the subject'"'"'s body movement.

11. The system of claim 10, further comprising:

a physiological data collection system, wherein the physiological data collection system collects physiological data associated with the subject'"'"'s physiological condition; and

wherein

the computing device further analyzes the physiological data.

12. The system of claim 10, wherein the eye tracking system tracks the subject'"'"'s eye movement by tracking the lens of at least one of the subject'"'"'s eyes.

13. The system of claim 10, wherein the body tracking system is an optical system.

14. The system of claim 10, wherein the body tracking system is a non-optical system.

15. The system of claim 10, further comprising an output device.

16. The system of claim 15, wherein the computing device plots the eye movement and body movement data versus time on the output device.

17. The system of claim 10, further including a storage device on which the eye movement data and the body movement data is stored.

18. A method for testing or training a subject'"'"'s visual and cognitive abilities during physical activity, the method comprising:

engaging the subject, who is wearing apparel, in a physical activity;

determining the position of at least one body component of the subject during the physical activity at a first predetermined plurality of times by monitoring indications on the apparel of the subject;

determining the position of at least one eye of the subject during the physical activity at a second predetermined plurality of times; and

temporally correlating the positions of the at least one body component at the first predetermined plurality of times and the positions of the at least one eye at the second predetermined plurality of times.

19. The method of claim 18, wherein tracking the subject'"'"'s eye movement includes tracking the lens of at least one of the subject'"'"'s eyes.

20. The method of claim 18, further comprising:

storing the positions of the at least one body component and the positions of the at least one eye on a storage device.

21. The method of claim 18, further comprising:

sending the positions of the at least one body component and the positions of the at least one eye to an output device.
