Abstract

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.

monitoring a second plurality of reactions of the patient using at least one of the computing device or a separate hardware device; and

based upon said first plurality of reactions and second plurality of reactions, determining quantitative values representative of the patient'"'"'s field of view, visual acuity, ability of the patient to track multiple stimuli, visual endurance and visual detection.

2. The method of claim 1 further comprising generating a single vision performance value representative of an aggregation of the field of view, the visual acuity, the ability of the patient to track multiple stimuli, the visual endurance and the visual detection.

3. The method of claim 1 wherein the first plurality of reactions comprises at least one of rapid scanning data, saccadic movement data, blink rate data, fixation data, pupillary diameter data, and/or palpebral fissure distance data.
