Patent ID: 8257087

Claim:
A method of improving visual ability of a subject during athletic activities, the method comprising: providing an artificial background, the artificial background having a first set of visual values assigned thereto, the first set of visual values comprising spectral reflectance, hue, and intensity; providing an overhead artificial lighting source, the overhead artificial lighting source having a first spectral distribution; providing a sporting object having a speed, trajectory, and rotation, the sporting object having a visual appearance, the sporting object having a second set of visual values assigned thereto, the second set of visual values comprising spectral reflectance, hue, and intensity; creating a low-contrast effect between the sporting object and the artificial background by altering the second set of visual values associated with the sporting object to substantially approximate the first set of visual values associated with the artificial background; enhancing the low-contrast effect between the sporting object and the artificial background by changing the first spectral distribution of the overhead artificial lighting source to a second spectral distribution; and requiring the subject using the altered sporting object to initially visually acquire the moving altered sporting object in front of the artificial background while being subject to the overhead artificial lighting source having the second spectral distribution.
