Methods and systems for obtaining, aggregating, and analyzing vision data to assess a person's vision performance
The present specification describes methods and systems for modifying a media, such as Virtual Reality, Augmented Reality, or Mixed Reality (VR/AR/MxR) media based on a vision profile and a target application. In embodiments of the specification, a Sensory Data Exchange (SDE) is created that enables identification of various vision profiles for users and user groups. The SDE may be utilized to modify one or more media in accordance with each type of user and/or user group.

9. The method of claim 1 wherein the quantitative values representative of the patient's ability of the patient to track multiple stimuli comprises data representative of a quality of the patient's ability to simultaneous track multiple elements in the second set of visual stimuli.
10. The method of claim 1 wherein the quantitative values representative of the patient's visual endurance comprises data representative of a decrease in the patient's reaction time over a duration of presenting the first set of visual and/or auditory stimuli.
11. The method of claim 1 wherein the quantitative values representative of the patient's visual endurance comprises data representative of an improvement in the patient's reaction time over a duration of presenting the second set of visual and/or auditory stimuli after a rest period.
12. The method of claim 1 wherein the quantitative values representative of the patient's visual detection comprises data representative of to what extent the patient sees the first set of visual stimuli.
13. The method of claim 1 wherein the quantitative values representative of the patient's visual detection comprises data representative of to what extent the patient can discriminate between similar colored, contrast, or shaped objects in the first set of visual stimuli.

presenting, via a display on the computing device, a first set of visual stimuli, wherein the first set of visual stimuli comprises a first plurality of visual elements that move from a peripheral vision of the patient to a central vision of the patient;
monitoring a first plurality of reactions of the patient using at least one of the computing device and a separate hardware device;
presenting, via a display on the computing device, a second set of visual stimuli, wherein the second set of visual stimuli comprises a second plurality of visual elements that appear and disappear upon the patient physically touching said second plurality of visual elements;
monitoring a second plurality of reactions of the patient using at least one of the computing device and said separate hardware device;
presenting, via a display on the computing device, a third plurality of visual elements that appear concurrently with said second plurality of visual elements, wherein the third plurality of visual elements are different than the second plurality of visual elements; and
based upon said first plurality of reactions and second plurality of reactions, determining quantitative values representative of at least three of the patient's field of view, visual accuracy, ability of the patient to track multiple stimuli, visual endurance or visual detection.
