Abstract
A first optic adjusts the focus of environment content in independent regions, and delivers the environment content to a see-through display. The display adds display content, and delivers environment and display content to a second optic. The second optic adjusts the focus of the environment and display contents in independent regions, and delivers the environment and display contents to a viewing point. The focuses of the environment and display contents are adjustable independently of one another and in different regions. Environment content may be similar in focus before and after passing through the first and second optics. Display content may be similar in focus to environment content after the display content passes through the second optic. A modifier also may darken, change opacity, or otherwise modify the environment content, independently in different regions; the display also may brighten, enlarge, or otherwise alter the display content, independently in different regions.
