Single depth tracked accommodation-vergence solutions

A method comprising:

• while a viewer is viewing a first stereoscopic image comprising a first left image and a first right image, determining a left vergence angle of a left eye of a viewer and a right vergence angle of a right eye of the viewer;
• determining, based at least in part on (i) the left vergence angle of the left eye of the viewer and (ii) the right vergence angle of the right eye of the viewer, a virtual object depth;
• rendering a second stereoscopic image comprising a second left image and a second right image for the viewer on one or more image displays, wherein the second stereoscopic image is subsequent to the first stereoscopic image;
• projecting the second stereoscopic image from the one or more image displays to a virtual object plane at the virtual object depth, wherein the second left image and the second right image are generated from an input left image and an input right image by applying one or more blurring filtering operations that blur one or more spatial regions of the second left image and the second right image relative to the input left image and the input right image, and wherein the one or more spatial regions of the second left image and the second right image are away from the viewer's foveal vision.
