Abstract
The technology provides an augmented reality display system for displaying a virtual object to be in focus when viewed by a user. In one embodiment, the focal region of the user is tracked, and a virtual object within the user focal region is displayed to appear in the focal region. As the user changes focus between virtual objects, they appear to naturally move in and out of focus as real objects in a physical environment would. The change of focus for the virtual object images is caused by changing a focal region of light processing elements in an optical path of a microdisplay assembly of the augmented reality display system. In some embodiments, a range of focal regions are swept through at a sweep rate by adjusting the elements in the optical path of the microdisplay assembly.
