BRIEF DESCRIPTION OF THE DRAWINGS
For a more complete understanding of the invention, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:
FIG. 1 shows a user undergoing a vision measurement and/or training session involving a computer, a binocular viewer, headphones and a game controller;
FIG. 2 shows a user and a binocular viewer, the viewing ports, auxiliary features and features to enhance alignment of the binocular viewer to the user's face;
FIG. 3A shows a side view of a user's eye and the elements of a display system that is capable of projecting a virtual image such that the image appears at a different distance, the focal depth, instead of the actual distance from the user's eye to the actual display screen;
FIG. 3B shows a cross-sectional view of a fluid lens that could be used to implement an optical subsystem;
FIG. 4 shows a top view of a binocular version of the display system shown in FIG. 3A illustrating, in particular, the effect that parallax may have on how a user perceives the distance to an object;
FIG. 5 shows an image that could be used to measure or train a user's vision acuity at different focal depths;
FIG. 6 shows an image that could be used to measure or train a user's vision acuity in each eye separately while the user is viewing the image with both eyes at the same time;
FIG. 7 shows an Amsler grid;
FIG. 8 shows a moving line test;
FIG. 9 shows a crosshair alignment pattern;
FIG. 10 shows a crosshair alignment pattern with a mapped disease-affected region of a user's eye;
FIG. 11 shows a vision measurement or training game involving incident and departing lines, a flash is also shown in a disease-affected region;
FIG. 12 shows a vision measurement or training game based on a circular form of computer tennis;
FIG. 13 shows a vision measurement or training game based on firing a gun at enemy objects emanating from a disease-affected region;
FIG. 14 shows a view of a three-dimensional, or stereoscopic, image fitted around a disease-affected region. The surface of the stereoscopic image includes a target that the user can interact with for parafovea training;
FIG. 15 shows how data from multiple games or the same game conducted at different times can be combined to create a single database;
FIG. 16 shows a flow chart of the data processing functions that could be used to modify a conventional computer application to incorporate vision training;
FIG. 17 shows a television and control box creating video images for a user based on data gained from vision measurement games; and
FIG. 18 shows a logical interconnection of the elements of a high integrity vision measurement and training system including security and system integrity information to ensure that the system is composed of proper elements and that they are properly interconnected.
