AUTOMATIC FOCUS IMPROVEMENT FOR AUGMENTED REALITY DISPLAYS
First Claim
1. An augmented reality system providing improved focus of objects comprising:
- a see-through display device including a variable focus lens positioned to be seen through by a user;
a microdisplay assembly attached to the see-through display device for generating a virtual image for display for at least one eye;
a memory for storing software and data;
a processor for determining a current user focal region under the control of software, the processor having access to the memory and being communicatively coupled to the microdisplay assembly; and
a focal region adjustment unit for focusing the variable focus lens in the current user focal region under the control of the processor.

Abstract
An augmented reality system provides improved focus of real and virtual objects. A see-through display device includes a variable focus lens a user looks through. A focal region adjustment unit automatically focuses the variable focus lens in a current user focal region. A microdisplay assembly attached to the see-through display device generates a virtual object for display in the user'"'"'s current focal region by adjusting its focal region. The variable focus lens may also be adjusted to provide one or more zoom features. Visual enhancement of an object may also be provided to improve a user'"'"'s perception of an object.

13. In an augmented reality system, a method for providing improved focus of objects comprising:
-
determining a field of view of a user in a three dimensional model of a space including a real object; determining a current user focal region; automatically adjusting a variable focus lens for at least one eye to focus in the current user focal region, the variable focus lens being positioned to be seen through by the at least one eye; displaying a virtual object at its real world focal distance in the user field of view; and visually enhancing an image of one of the objects in the user field of view. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
