[0019] refer to Figure 3A with 3B , which delineate various aspects of the AAD system. refer to Figure 3A , a simple diagram shows that instead of stereo vision ( figure 2 ) can be utilized to provide each eye with the perception of three-dimensional depth layered within the perceived image using two complex images, one for each eye, for each image's different Aspects (14) have different radial depths of focus (12).
[0020] refer to Figure 3B , we have determined that the typical human eye is able to interpret about 12 layers of depth based on radial distance ( Figure 3B Layers L1-L12 in -reference number 16). A near field limit (78) of about 0.25 meters is the approximate closest depth of focus; a far field limit (80) of about 3 meters means: any item further than about 3 meters from the human eye receives infinite focus. The layer of focus becomes thinner as one gets closer to the eye; in other words, the eye is able to perceive very small differences in focus d...
